Maico and Dan moved 5 shielding blocks from ITE to ITW. The ITW is configured to take proton beam.

  1068   Tuesday, September 15, 2015, 08:24 David WangSouth Hot-CellRepairTM1UCx 13Leak check on TM1 window circuit soldering stems in service cap.

I did a leak check on TM1 window circuit  2 soldering  stems in service cap.The round side panel was opened for the job. I sprayed helium on the stems for 10 seconds. The leak detector got a tiny response(from 0.0xE-9 atm.cc/sec to 2.0xE-9 atm.cc/sec). The test  repeated again. The second time, LD climbed  to 1.2xE-9atm.cc/sec. It looks like there is a very tiny leak on the stems soldering spots. But , this is not the same leak we found from SHC helium spray which LD climbed to 1.4xE-8atm.cc/sec with only one click helium spray by Chad.

 Because of the high air flow at SHC when the round panel is removed, The result is not conclusive. The same test is done at silo without  airflow. We found a big leak on this soldering stems . See later e-log.

 Leak check TM1 window circuit soldering stems inside service cap when module is located at NE silo. LD base LR 0.0xE-9atm.cc/sec.  Only 1 second tiny amount  helium sprayed on stems soldering joints . LD got a quick response to high E-7 atm.cc/sec.Test is repeated again with same result.  See attachments

Chad and I leak checked the HS line at SHC. No leak. Leak rate 0.0xE-9atm.cc/sec.

Helium pressure test HS line at CS with 70 psi for 2 minutes. Base  leak rate 0.0xE-9atm.cc/sec. No response. The line is leak tight.

  1079   Wednesday, September 23, 2015, 14:35 David WangConditioning StationStandard OperationTM4Ta#46TM4 has been connected at CS

TM4 has been connected at CS. Turbo- pumps and water system are started and running . The HV cover has been installed on the module. Everything is good so far.

  1080   Thursday, September 24, 2015, 07:00 David WangConditioning StationMaintenanceTM4Ta#46Turned off TCS all vacuum pumps and water pumps.

TCS:MP1 back up pressure went up too high (700mtorr).I turned off all the pumps.The TCS is under vacuum still. TCS water  package cooling fans showed error on control page.The water pumps are stopped  also.

Restarted the vacuum pumps 40 minutes after stopping. Everything is back to normal. The MP1 back up pressure need to be monitored frequently before we have a final solution on this issue.

Reset the CS cooling package on roof and restarted the water  pumps. The system is running good so far.

During the weekend condition The TM4 spark at 30KV without vacuum response. It is confirmed the spark is from the top TM4 this morning.The flexible cables in a  black wire sleeve which is used for febiad X pin connection drooped too close to the TM4 surface plate, and caused the sparking. The problem is fixed by Anders and David. The cables is put back where it should stay.  After test, no sparking on the top.
