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. |

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 |

chad fisher | South Hot-Cell | Repair | TM1 | | TM1 Window Gasket Replacement |
Replaced the custom silver gaskets on the entrance window panel of TM1 this morning...this has eliminated an sign of leak at this joint, however there appears to still be a leak somewhere...a good distance from the vcr joints of the window as we are getting a drift response.
Chad sprayed helium to soldering stems in containment box which we suspected with leak last week. With 1second click on helium, after 80 seconds waiting time , the LD started to show leak up to 3xe-9atm.cc/sec.
Chad sprayed helium close to service tray and vacuum chase. with 1second click on helium , after 30 seconds waiting time, the LD started to show leak up to 2Xe-8 atm.cc/sec.
After this test, we knew the leak is somewhere in service tray or service cap, but not the soldering stems in containment box we suspected before.The further investigation is needed. |
