CSBF Integration Status

Here is a summary of today's activites at CSBF.

• The preparation of the hang test started at 6 AM (CDT).
• The weight of the payload w/o rotator and with the bottom solar panels added was measured as 3605 lbs before moving out for the hang test.
• After having the payload on the high dolly, it is found that the lift crane is too big to lift the payload with the bottom solar panels. So the bottom solar panels were removed and re-assembled at the outside for the hang test.
• The hang test in solar panel power mode was started around 9 AM (CDT).
• At the beginning of the hang test, the payload related function was tested with the instrument was in flight mode with the muon trigger.
• After the function test, the instrument LPT was completed except the shutdown safe of the SFC1 at the end.
• The shutdown safe indicator light did not turned on either at the CDM monitor and the master trigger board.The SFC1 restarted with a power re-cycle by the CDM, but the connection did not establish maybe due to an incomplete rebooting of the SFC1 possibly asking the disk check and waiting for the keyboard return. Decided to power off to debug the problem inside the high bay area with keyboard and console monitor. But when the SFC1 was powered on at the bay, it booted fine with the server program running OK. So the problem has not reproduced inside. It maybe due to a hot temperature outside (~38 deg. C).
• In case if it was due to the disk check, the option to check disk should be off before the launch in order to avoid this problem in the flight when the SFC be rebooted and have the same situation. This is a part of the SFC CPT, I heard, so it should be off before the launch. It is only on when in debugging mode and when the disk s were bad as in the last year's integration.
• By the time, the instrument LPT was over except the SFC shutdown safe problem, it was about 1:40 PM.
• During the hang test, the data flow and commanding from/to the UMD either in TDRSS mode and in Iridium mode were tested by sending commands and receiving data. Also received data were checked by the Cplot program.
• During the LPT, the muon data in CER shows a unit of PMTs (16 each) with higher number of hits above sparsification threshold. It needs to be checked by the CER group. Will send an e-mail to them for checking after transferring data to the cdps3.

Here are things planned to be done.

• Pre-scaling of different trigger flag data are being coded and debugged by Prashant. This is necessary coding before the burn-in starts.
• The CDAQ code in SFC2 will be updated with the directory change code before the burn-in and tested if possible. Otherwise, it will be tested during or after the burn-in test.
• For the burn-in test, a client PC will be prepared with dual Ethernet card so that data flow can go to the UMD SOC for shift.
• Chercam HSK problem debugging after the burn-in test.
• TCD 12 V HSK attenuation circuit installation after the burn-in test.
• Update of manuals.
• Copying and backup of new integration data into cdps3 at UMD and client PCs at CSBF.

Here are updates related with the hang test, burn-in and packing.

• Burn-in will be between 9 AM (EDT) 2nd of Aug. and 9 AM (EDT) 5th of Aug. for 72 hours. It will have a Iridium mode between CSBF and UMD SOC for 2nd and 3rd. It will be TDRSS mode for the day time of the 4th. If possible, keep the Iridium mode on during the nights.
• MOR/MRR schedule is being arranged as the 6th of August.
• Shipping of the Instrument container is being arranged by Linda/Dave of WFF. Will see a plan on Monday.
• All other GSE crates will be sent via a usual sea shipping. It is going to be leave from CSBF on the 15th of August. All spares should be delivered before the date even if some can not be delivered before the 8th when UMD crew will leave CSBF if everything goes well.

Please let us know if you have any questions/comments/suggestions.

Cheers, MooHyun.

Here is a summary of today's activites at CSBF.

• There was no power stoppage during the overnight muon run again.
• Test data in 24th and 25th were transferred to the cdps3.
• Debugging of the reduced hsk data continued today by Prashant with the Iridium connection from the CDM. Finally, he came up with a solution with the problem. Now the reduced hsk in the Iridium mode works even with two different sets, one original and the other for the CER and TCD. The details will be explained by Prashant in a separate e-mail.
• After the test, there were some update discussed related with the 2 channels vacant for the 2nd packet and sequence of the hsk display. For example, TCD and CD related hsk data will be grouped together.
• Chercam HSK signals from pin #10 and 22 in the oscilloscope were captured by the digital camera and uploaded on the black board for a reference.
• SangEun continue working on the SIP interface coding. Has been working very hard and wants to present the progress report after the current coding on the serial communication is done since it requires lots of concentration.
• Fritz completed 2 side foam walls today and one of them was installed.
• The event display program tested at the cdps5 and worked fine. Dave and Fritz appreciated the event display that they now know the CREAM-IV instrument is working. The tracking also worked when there are not so many noise hits in tSCD and bSCD.

Here are things to do.

• Confirmation of the reduced hsk display in Iridium mode in the morning with an updated hsk display.
• SFC1/2 CPT tests with those 2nd bootable disks.
• Chercam HSK problem debugging.
• TCD 12 V HSK attenuation circuit installation.
• Mechanical integration continues by Fritz. The other two side foam walls would be completed. If possible skirts between those walls and the pallets will be worked on.
• Update of manuals including CPT.
• Copying and backup of newly taken integration data into cdps3 at UMD and client PCs at CSBF.
• Adding another Ethernet card to cdps5 for a dual connection to local network and to outside.

Please let us know if you have any questions/comments/suggestions.

Cheers, MooHyun.

Here is a summary of today's activites at CSBF.

• There was no power stoppage during the overnight muon run again.
• The CPT with CDM, which consists of 4 power modes, completed tonight.
  • The remaining LPT of sub-detectors for the first CPT (GSE power supply) started from morning and ended at about 2 PM with an updated manual.
  • During the LPT, the data flow to the UMD SOC started but stopped around noon due to a rain outside at CSBF. No more connection until the end of the CPT. JiHye got more experience with this test especially on the data relay server setup at the cdps3. Plan to have an SOC expert training next week. Candidates are Dr. Kim, Opher, Ki-Chun and Brian. Other undergraduates can join the training also.
  • Updated manuals will be uploaded on the blackboard before Monday.
  • For the next 3 CPTs with different power modes (battery, battery being charged, and maximum power mode), CAL/tSCD/bSCD/CER pedestal runs in addition to the background muon runs in flight mode were carried out to test commanding from the Client PC and noise measurements in different power modes. They were all working OK w/o any problems.
  • Manuals were updated based on today's experiences with changes in the cdaq software and parameters.
• The old PYL box shipped back to PSU for a repair. It will become a spare box.
• S3 threshold studied with different threshold values and the results are on the black board. With the correct parameters being changed, the S3Lo and ZLo were changed as expected.
• CD threshold issue related with the high ZHi rate problem solved. It was due to the wrong connector wiring and the bad connector at the MXR box. With Nick/Isaac's advice, the CD threshold wires moved into the connector pin #1 and #2 where TCD threshold control wires are in #3 and #4. After that, the CD threshold worked as expected. The measurements results are also on the same excel file as the above study. Also the CD signals and connector picture were uploaded on the black board as a reference.
• Prashant prepared cdps5 as a data relay machine in the local network. So the data taken in boram.creamnet will be copied to the cdps5 at the same time during the CSBF integration. This is very useful and would be better to be a part of future setups at CSBF and ICE.
• JiHye installed an event display program prepared by HoSeok at the cdps5. The same program is at UMD also.
• Debugging of the reduced hsk data could not be tried today by Prashant due to the CPT.
• SangEun continue working on the SIP interface coding before and after the CPT work.

Here are things to do.

• Reduced hsk debugging.
• Chercam HSK problem debugging.
• TCD 12 V HSK attenuation circuit installation.
• Mechanical integration starts from tomorrow by Fritz. The power of the instrument will be off during the mechanical work.
• Update of manuals including CPT.
• Copying and backup of newly taken integration data into cdps3 at UMD and client PCs at CSBF.
• Adding another Ethernet card to cdps5 for a dual connection to local network and to outside.

Please let us know if you have any questions/comments/suggestions.

Here is a summary of today's activites at CSBF.

• There was no power stoppage during the overnight muon run again. Larry told me that the heat blocking by the card board could reset the power supply. Also suggested to have the UPS connected to the GSE notebook computer so that the UPS power can be monitored. Or the Power GSE Labview program needs to have logging of the power data on. I will try to do both.
• Chris Field (CSBF) confirmed that CSBF power monitoring does not show any power off/on at that time. There are many CDM equipment with power on for 24 hours with power outlet next to what we are using and they did not have the problem.
• I confirmed with Dave that we could have the remote commanding and data flow this year since we still have the port waiver permission valid even though it has to be updated for another year asap.
• The CPT with CDM, which consists of 4 power modes, started from this morning.
  • The Ether adapter cable, mating two 9 pin D-sub connectors with one 9 pin D-sub connector, was re-made with the mashed wire cables since the single wire cable is not qualified for flight and already failed in the acknowledgment connection.
  • It took longer time than usual since not only we had SangEun as the main person but also it was the first CPT with the CDM for both Science and CDM.
  • CDM side tests in muon run in flight mode took about 3 hours before the instrument test started.
  • Common electronics tests from SFC1/2 shutdown-safe tests to the all detector data taking before each sub-detectors' LPT could be finished by 7:30 PM.
  • It seems to me that this part of the test and together with the sub-detectors' LPTs (actually most of the instrument CPT) could be done only once during the CDM integration.
  • The remaining LPT of sub-detectors for the first CPT will continue from tomorrow morning.
  • For the next 3 CPTs with different power modes, will do mostly muon run in flight mode since only differences are in power mode not in any connections. Simulating the flight mode seems the best for the CDM test in the combined CPT.
  • Manuals were updated based on today's experiences with changes in the cdaq software and parameters. Additional manual for the CDM integration CPT is being made.
• The repaired MXR box delivered and replaced with the PYL box which had a bad shaper channel. I thought it was a replacement of the PXR which is giving time out error. But the PXR box is a special box and Nick told me that it is not necessary to replace it with current error rate. The old PYL box will be shipped back to PSU for a repair. It will become a spare box.
• S3 threshold tuning continued. Nick clarified which values to be adjusted and definition of each channels as follows.
  • SCI_TCD THRESHOLD, 8, 0x01, 500
  • SCI_TCD THRESHOLD, 8, 0x05, 500
  • (Change 500 to anything you wish > 100 and <=4095)
  • The following should be helpful (but is true for S3 only):
  • THR0 -> ZLo
  • THR1 -> S3Lo
  • THR2 -> Unused
  • THR3 -> S3Hi
• Debugging of the reduced hsk data could not be tried today by Prashant due to the CPT.
• SangEun continue working on the SIP interface coding before and after the CPT work.

Here are things to do.

• Continuation of CPT with the CDM. Planning to have the UMD connection tomorrow with 1 hour commanding window in 2 hours and full data flow from 10 AM (EDT) to 5 PM (EDT). UMD SOC, please be prepared from 10 AM.
• S3 threshold value tuning.
• Reduced hsk debugging.
• Chercam HSK problem debugging.
• TCD 12 V HSK attenuation circuit installation.
• Update of manuals including CPT.
• Copying and backup of newly taken integration data into cdps3 at UMD and client PCs at CSBF.
• Adding another Ethernet card to cdps5 for a dual connection to local network and to outside.

Please let us know if you have any questions/comments/suggestions.

Here is a summary of today's activites at CSBF.

• On Sunday early morning around 6:30 AM (CDT), there was a kind of power stoppage for about guesstimated 10-15 minutes and the muon run was stopped. The SFC was rebooted and cdaq_serv program was started but not the instrument power and HV which requires commanding. The data were copied to cdps3.
• MXR box cabling and labeling were done.
• Muon run in flight mode started around 11:30 PM.
• This early morning around 6:30 AM again, the same problem happened and muon run stopped.
• Asked Chris Field (CSBF correspondent) to check if there were any activities related with those accidents. But the question is why only CREAM instrument power was off at the almost same time within 10 minutes for two days. The CDM machines and CREAM Client PCs did not show any signs of power off. Chris so far hasn't found any related activities at CSBF. Only one difference between last two nights and previous nights are the change of the power outlet which was used for the UPS of the CREAM Power GSE. Prashant still investigating by looking at the log file of the SFC1 which was used during the runs.
• MXR box shipped back to PSU for a repair and a replacement of the pxr box which gives time out errors from time to time (~ 4 per 200 events).
• The remote commanding and data flow test with (CSBF<->WFF<->UMD SOC) connection started from the morning to the end of the day.
  • At the beginning, there was a problem in the data flow from the SFC1 to the Client. Turned out that the SFC1 setting was not fully updated yet. Switched to the SFC2, the data flow started. Prashant is going to update the SFC1 setting.
  • At UMD side, cdps1 and could not receive the data for about 3 hours due to the firewall setting related with the allowed IP addresses. Even though it is safe to block the non-local network machines, I think that it is better not to block those IP addresses which were already in the setting. This is a lesson learned during today's test.
  • In summary, the data flow part could be tested at the SOC. The remote commanding and Iridium mode tests are to be done in tomorrow which will start from 9 AM (CDT).
• The CD threshold control cable's BERG connector was repaired by the CSBF person and re-installed.
• S3 threshold tuning has started. Tried to reduce the threshold values in a few possible channels the script but did not work. Nick suggested new values in different channels. The first ones of each PMTs would be changed from 100 to 150 to reduce the S3Lo rate. Haven't had time to take data due to other priority.
• Debugging of the reduced hsk data continued by Prashant by using a Iridium connection.
• SangEun continue working on the SIP interface coding. A problem with the number "3" character being broken in a serial port communication hold his progress. Has asked may experts but no solution yet. Since SIP is the serial port communication, it is the most critical for him to understand and master the serial connection.

Here are things to do.

• Continuation and completion of the remote commanding and data flow via Iridium mode at UMD SOC via WFF.
• Power failure investigation. Until the investigation is over, stop the overnight muon run for the safety.
• S3 threshold value tuning.
• Reduced hsk debugging.
• Chercam HSK problem debugging.
• TCD 12 V HSK attenuation circuit installation.
• Update of manuals including CPT.
• Copying and backup of newly taken integration data into cdps3 at UMD and client PCs at CSBF.
• Adding another Ethernet card to cdps5 for a dual connection to local network and to outside.

Please let us know if you have any questions/comments/suggestions.

Here is a summary of today's activites at CSBF.

• Muon run in flight mode during overnight was running w/o stopping. Data copied to cdps3.
• Nick has looked at the muon data with the well tuned threshold values by Isaac and the TCD signals seem more reasonable even though MXR problem still prevent for the final conclusion.
• Chercam HSK display problem debugging continue. Brian and Jeremy confirmed that the connector was not modified during the test. Next step is to look at the HSK USB output directly.
• CD HV monitoring values calibrated again with the hsk display conversion as 1, which is raw voltage value, in the morning. And a set of formula obtained. The excel file was uploaded on the black board and the new conversion factors implemented into the hkconv4.dat. Now HV values seem consistent with the real values.
• A CD pulse shaper board delivered from PSU. Jason replaced the board and the CD signals from muon triggers look reasonable now.
• S3's bad smb connector was replaced with Jason's good one yesterday. The muon data taken with the new cable shows improvement even though still waiting for the MXR problem resolved for the final confirmation.
• Legs installed into the pallet and the CREAM-IV instrument moved next to the CDM for the integration.
• Power and Heater cables are routed and connected to the connectors.
• After the safe to mate test of power, sensor, and heater cables to the CDM, they are connected to the CDM.
• The temperature sensor cable for the CDM tested and found one connector for the CER -X-Y (J15) was connected to the wrong position. (J33) Also connectors for the J16 (SCD -Y PCB) and J18 (?), which are not necessary, were not available. Instead two sensor for SFC1 and SPAR. BOX STACK were made at UMD and connected to the two positions but no signals. Tried those sensors in different position and they were working. Problem with those positions? Need further investigation if we have time. Or just fly with existing sensors (16 out of 18 original) which are good enough.
• The SFC power on signal from the SFC interconnect module (Switch) did not work. It was fixed by removing pin #5 from the connector since both pin #4 and #5 had +4.7 V instead of just pin #4 thanks to Larry's suggestion. This bug fixed in the next version of the board but not with this board and Peter might did the same thing for the CREAM-III integration at WFF.
• Turned on the CREAM-IV instrument with the CDM power supply and muon run in flight mode with direct Ethernet connection between SFC and the CDM Client PC tested and OK.
• Ethernet cables between SFC1/2 and the CDM tried but not working. It turned out the connectors for the CAT5 cables were bad. The climped wires were loose. Will be fixed tomorrow with climping and soldering if necessary.
• Change of IP addresses of cdps1 and 2 found to be not possible in WFF side as we experienced before. Dr. Kim moved cdps1 and 2 to the lab for the remote commanding test on Monday and Tuesday. Still need to set the WFF IP addresses for unblocking.
• Second Ethernet card installation into the cdps5 tried but in vain by Prashant. We may have to buy a new card in the Radio shack and try it.
• Debugging of the reduced hsk data continued by Prashant.
• SangEun has been working on the SIP interface coding.

Here are things to do.

• Integration with the CDM continue with the Ethernet connection. The CDM module plan to be mounted under the instrument tomorrow.
• SFC Ethernet cable replacement with new ones. Existing ones are temporary with bad connectors.
• Reduced hsk debugging.
• Chercam HSK problem debugging.
• TCD 12 V HSK attenuation circuit installation.
• RPSC presentation preparation.
• Update of manuals including CPT.
• TCD S3 tuning.
• CD integration.

Please let us know if you have any questions/comments/suggestions.

Here is a summary of today's activites at CSBF.

• The MXR problem did not disappear during the overnight run. Jim came in the morning and confirmed which cable causes the time out error. The cable lengths between concentrators are checked and sent to Nick. A newly made cable (10 pin flat twisted cable) by Isaac&Nick has been sent via FedEx priority.
• SCD heat pipe fitting was given to Fritz. He has spent time to figure out how to install them. Dave and Fritz talked with Scott on his trip schedule for the installation.
• -X side, sparsification boards stack and master trigger board, has cables cleaned up. So besides SFCs which will be done after the SSDs delivered and integrated, all cablings of instrument are cleaned. I uploaded pictures of cabling on the black board under CSBF integration.
• The disconnected Chercam HSK MUX connector replaced and saw most of channels in blue colors except 8 HV values. Asked Laurent if they are OK or not.
• TCD Power hsk mapping conversion modified to have correct display. Still there is a saturation problem with the 12 V monitoring channel. Asking Isaac for their pin mapping for clarification. Other channels are OK now.
• Second boot source problem with the HSK board solved by Prashant with Larry's advice.
• Debugging of the reduced hsk data being worked by Prashant.
• SangEun has been working on the SIP interface coding.
• Cleaning up of integration data inside 3 client PCs has started. Going to have enough back ups of CREAM4 integration data in 3 PCs. Those data taken at UMD seems too big (maybe ~ 20 GB) to be transferred in one or two day. If they don't have to be copied later, we can plan to bring those data by an USB external disk when we return to UMD. Please let us know whether you need those data before that or not.

Here are things to do.

• Reduced hsk test with the Iridium connection from CDM setup.
• Integration with the CDM.
• Installation of SSDs into SFC1/2 if delivered.
• Power cable to CDM installation if delivered.
• CD housekeeping conversion factor in the housekeeping table.
• TCD Power +12V mapping debugging.
• Update of manuals including CPT.
• TCD MXR re-cabling when delivered.
• TCD S3 tuning.
• CD integration from Thursday.
• Daily data copying to the cdps4 until we can have 2 Ethernet cards and make it working.

Please let us know if you have any questions/comments/suggestions.

Cheers, MooHyun.

Here is a summary of today's activities at CSBF.

• Jim re-clamped the flat cable connector on the MXR box. The error message does not show up after that in test mode whole day. But as soon as the muon run in flight mode started in a few minutes, it came back. We will see if this disappears as time goes on as in last two nights.
• Thermal/Vacuum chamber was shown by Joseph. The specification is summarized and uploaded on the black board.
• ZLo puzzle solved by replacing the LVDS cable, which was used from at least last flight. Now the ZLo trigger behaves as we expected.
• Jim told me that the ZLo trigger generated in the TCD trigger circuit will be sent to the MT independent from the MT confirmation as we expected from the ZLo trigger behavior. But the digitization starts only when the MT sends a confirmation (decided based on the trigger logic) trigger within 1 or 1.5 micro seconds.
• Debugging of the reduced hsk data being worked by Prashant.
• Data copying for the last 3 day's CPT data are done.
• SangEun has started working on the SIP interface coding.
• Light shielding of box +X, -Y boxes are done. So all boxes are now light tight.
• Cabling in -X sides, where Switch box, SFC, Command, CAL Trigger are located, are cleaned up. So only -X side needs cleaning up.
• Dave and Fritz came around 5:30PM. They will start work from tomorrow.
• Power cable and 2 SSDs are sent from UMD. (Larry/Dr. Kim)

Here are things to do.

• TCD mxr debugging.
• S3 tuning.
• CD housekeeping conversion factor in the housekeeping table.
• CD integration.
• Repair the MUX cable connector (9-pin D-sub connector) for the Chercam HSK.
• CDAQ remaining works including reduced housekeeping. (Prashant)
• Clean up -X side cables.
• Test of temperature sensors for CDM.
• Power cables for CDM shipping on Monday. (Larry) etc...

Please let us know if you have any questions/comments/suggestions.

Here is a summary of today's activities at CSBF.

• CPT of instrument started. This time, SangEun is the one who excuted all the command and recording.
• CPT of SFC1/2 finished. Some of procedures in the manual need to be corrected and will be done.
• CPT of most of common electronics boards done up to the number 7.n. before the testing of the prescaler.
• Housekeeping board 2ndary boot source did not work during the CPT. Prashant will work on this with Larry's help.
• Just during the muon run in flight mode starting, Prashant found the mxr problem disappeared. But as soon as I touched a cable, which I don't remember, the problem came back. It may mean that there is a bad connection in the box?

Here are things to do until next Tuesday when Dave comes here.

• CPT of instrument.
• TCD mxr debugging.
• S3 tuning.
• CD housekeeping conversion factor in the housekeeping table.
• CDAQ remaining works including reduced housekeeping. (Prashant)

Here is a summary of today's activities at CSBF.

• Muon run in flight mode during last night stopped as soon as the Chercam LED run started due to the missing delay value table. Fixed.
• Chercam/TCD/CAL groups replied that LPT data look OK so far except the mxr, Chercam housekeeping data, and CAL pedestal noise with HV on.
• Chercam housekeeping display and hk file sent to Laurent for checking and turned out the MUX control cable connector had cable off. Will repair it.
• Calorimeter HPD boxes +Y and -X are light shielded with black tapes with easy removal during the recovery in mind. Reduced the pedestal RMS noise due to light leak to the reasonable level. Please see the attached ppt file for the comparison. Will do remaining two other boxes light shielding tomorrow.
• Turn-on SFC2. The same as in the SFC1. Disk checked due to the fact that the 2nd disk was removed. After checking the disk, it is OK. Synchronized all necessary files the same as in the SFC1.
• A SIP simulator turned out to be at WFF and will be returned to CSBF next week. Then it will be shipped to the UMD since the notebook computer needs to be replaced with one with bigger screen. Lucky that they found the box.
• TCD mxr box debugging continue. Nick sent the eClient software for the connection and data test. After looking at those data taken with the software, Nick thinks that there should be no problem in the mxr hardware but in the CDAQ software where the TCD read out takes place. So Prashant tried with the CREAM-III CDAQ but the same problem. Still a pending problem. Pictures of mxr box sent to TCD/CD group members for further check.
• RawCAL was on in the beginning of the day. Could not found the reason yet. Needs to test it in the CPT tomorrow.
• Housekeeping board 2ndary boot source did not work. Investigate it in the CPT also.
• Reduce housekeeping code being debugged to be completed before the CPT with the CDM starts on the 21st in the current schedule.
• An overnight muon run in flight mode started before dinner and still running.
• Larry completed the Power cable for CDM and shipped to CSBF.

Here are things to do until next Tuesday when Dave comes here.

• CPT of instrument.
• TCD mxr debugging.
• S3 tuning.
• CD housekeeping conversion factor in the housekeeping table.
• CDAQ remaining works. (Prashant)
• Power cables for CDM. (Larry)
• etc...

Please let us know if you have any questions/comments/suggestions.

We have finished LPT of the CREAM-IV this afternoon and are going to have a long muon run in flight mode over night. It was a lot of works done compared with usual works at WFF.
Here is a summary of today's actvities.

• Registration at the visitor center.
• Un-packing of 2 gray crates for GSE setup.
• Un-loading of the CREAM-IV instrument from the sea container back to the high bay.
• Turn-on SFC1. It turned out that there was an disk check message maybe due to the fact that the 2nd disk was removed. After checking the disk, it is OK.
• A SIP simulator was prepared for SangEun by Joseph. They are still investigating where the SIP simulator, which supposed to be sent to UMD 2 weeks ago, went by asking FedEx. Amazing story is that the size of box has changed to a smaller box in the FedEx record. So FedEx is also not that safe, I guess.
• Inventory of electronics boards (CREAM-IV and spares) are checked and confirmed at CSBF. The file sent to SangKyo to update it after confirming.
• LPT was done w/o any problems except the two issues.
  • LED run in calorimeter showed noise increases due to light leaks from strong lights in the bay. Covered with a black cloth and they disappeared. Will do final shielding with black tapes in the middle sections in a manner that the tapes can be removed easily in the recovery procedure.
  • Housekeeping data (HV values) in Chercam were not within green range, which were the case for a while even at UMD. They were OK a month ago when the Chercam integration was over. Asked Chercam group to check the muon data.
• An overnight muon run in flight mode will be started before going back to sleep.

Here things to do until next Tuesday when Dave comes here.

• TCD CPT of all detectors.
• mxr debugging. (TCD)
• S3 tuning. (TCD)
• CD housekeeping conversion factor in the housekeeping table. (CD)
• CDAQ remaining works. (Prashant)
• Power cables for CDM. (Larry)
• etc...

Please let us know if you have any questions/comments/suggestions.
