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 25, 2011, 16:57, Bevan Moss, Conditioning Station, Standard Operation, TM4, , Turbo Pump 1 issues
|
Roughing on TM1 started at ~15:00 today by ~16:30 the module had reached a pressure of ~200 mTorr and the turbo pumps were turned on. TP1 failed to achieve normal operation and we running at approximately 4KRPM and 50W with 6.1 A of current draw. TP2 was able to achieve normal operation. The controller for TP1 was then powered off and back on but that failed to resolve the issue. The controllers for TP1 & 2 were then switched at which point TP1 again failed normal operation and TP2 achieved it, thus eliminating the controller as the issue. The turbo pumps have been turned off and the roughing pump left on for overnight in case Vacuum group wishes to do any additional diagnosis. |

Base Pressure: 0.0x10-4
Stable Leak Rate: 0.0x10-9
Leak check of tube heater circuit, containment box side was performed.
Initail check at tube heater block on source tray yeilded a response 60 sec after the 2 second spray of helium. The response was very small and recovered immediately.
This area was checked twice more but the reponse could not be recreated.
Joint at the waterblocks was tested with an intial 2 sec spray. No response after 60 sec.
Waterblock joint was tested again with a 4 second spray. No response after 60 sec.
