David Wang | South Hot-Cell | Repair | TM2 | | TM2 pressure bubble test on RU water blocks. |
July-06, 2015. Chad , Grant and I did the bubble test on R,U water blocks. We suspected the leak on the R,U circuit is from C seals on the water blocks so we did this test first. I applied both air and helium to R,U circuit , Chad applied snoop soap on the R,U water blocks.The air and helium pressure was increased from 40 psi to 90 psi Max step by step.Chad did not see any bubbles on the water blocks during the test. Since we did not find the leak source, we decided to do vacuum helium check on the all joints and c-seals of the R,U lines later. Finally, We found the leak by vacuum helium spray the day after this bubble test. See other e-log. |

David Wang | South Hot-Cell | Standard Operation | TM2 | no target | TM2 no target electrical check at SHC. |
I did a TM2 no target electrical check at SHC this morning. A to RU at 500v is 250K which is low. anode- x pin is dead short to 60kv bias. RU is dead short to 60kv bias( as before). see attachment |

Bevan Moss | Conditioning Station | Standard Operation | TM2 | | TM2 no source tray 55kV 1 hour |
Today 55kV was applied to TM2 and held for over 1 hour with the EINZEL at 27.5kV. There were 2 sparks and the current was unstable at this voltage but this test should be considered a success. Once again while bringing the voltage up the canbus continued to be a problem. After successfully passing the test I continued to raise the BIAS and EINZEL. A spark at 57kV tripped a controller for the vacuum and the canbus. As stated before I believe the module will reach 60kV and that there is an interaction between the EINZEL and the BIAS. I am not certain if that interaction is internal or external to the module. Attached is a screen shot and the dumped data. |

David Wang | South Hot-Cell | Standard Operation | | | TM2 new source tray has been remotely transferred from TH into SHC successfully. |
TM2 new source tray has been remotely transferred into SHC successfully. The transfer table has been moved back to TH within 1 hour. I swiped the table and found about 150counts contamination. It is much better comparing to last time using since we removed this table out of SHC as quick as we can. The table will be cleaned with windex after Target Hall is surveyed. |

David Wang | Conditioning Station | Repair | TM2 | | TM2 leak check at conditioning station |
I leak checked TM2 at conditioning station this morning. All air to vacuum seals on the top of the module are good. All water lines are pressured with 60 psi helium for minutes each. One of the tube heater + water line( 2lines for tube heater + for supply and return) has a huge response on 60 psi helium pressurizing. The leak rate went from 6.0xE-9atm.cc/sec to maximum leak rate in 5 seconds and I saw a pressure increasing either. when I pressurize the other side tube heater + line ,the leak detector also had a response,but it is slower than first side .Since the top of the water adaptor isn't sealed , so I think the leak should be in one line only. All other water lines are leak tight since I didnt see any obvious response on leak detector at 5 to 6x E-9 atm.cc/sec which is very low on leak rate. |

David Wang | Conditioning Station | Repair | TM2 | | TM2 leak check at TCS, water test. |
The following water circuits in TM2 are connected at TCS and running with water now : target oven+ - ( one circuit), tube heater+ -( one circuit), coil1 and 2(one circuit), MSP, and EE. The HS and window are open circuits now so they can not be supplied with water. During the check before we knew HS and window circuit were close to perfectly sealed. So, The test result should not be affected without them
The TCS water pumps are started at 8:28 AM. All TCS high vacuum gauge readings are getting slight better after that. |

Anders and I finished the most part of TM2 water lines helium pressure test yesterday.I list the system parameters and test result as below:
TCS IG1: 9.8XE-8 torr, TCS IG2: 9.6Xe-7 torr, TCS IG1S: 3.5XE-9 torr, TCS CG1A: 10 m torr
Helium pressure: 70 psi. Test time: 5 minutes for each individual circuit. 1 hour for all lines together test.
Leak detector base leak rate:0.0 X E -9 atm.cc/sec, base pressure 0.0X E-4 torr. LD was always restored or closely restored to the bottom scale after each individual test.
