Tuesday, September 15, 2015, 08:24, David Wang, South Hot-Cell, Repair, TM1, UCx 13, Leak 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. |

Thursday, September 17, 2015, 11:50, David Wang, Spent Target Vault, Repair, TM1, , TM1 window circuit leak check
|
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 |

Tuesday, September 22, 2015, 13:15, David Wang, South Hot-Cell, Standard Operation, , Ta#46, Leak check on TM4 HS water line with new Ta#46 target. at SHC
|
Chad and I leak checked the HS line at SHC. No leak. Leak rate 0.0xE-9atm.cc/sec. |
|
Wednesday, September 23, 2015, 14:32, David Wang, Conditioning Station, Standard Operation, TM4, Ta#45, Helium pressure test on TM4 HS line at CS
|
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. |
|
Wednesday, September 23, 2015, 14:35, David Wang, Conditioning Station, Standard Operation, TM4, Ta#46, TM4 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. |
|
Thursday, September 24, 2015, 07:00, David Wang, Conditioning Station, Maintenance, TM4, Ta#46, Turned 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. |

Tuesday, October 06, 2015, 13:00, David Wang, ITE, Repair, TM4, , spark on top of TM4 in ITE
|
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. |
