|
I did a 5KV mega test on TM3. Only5Mohm @5kV between coli line PQ and chassis(ground). It confirmed the close gap between P,Q and GE. Other lines are ok. See attachment. |

PLEASE NOTE: the resistance values for A and B on David's attachment are not correct since these measurements were done after Chad removed the target and the heat-shield bracket was moved, so consequently the water lines were not at their nominal locations. Once they were back in plac,e David took another measurement and the resistance values for A and B showed also 3,000 MOhm (as it was for most of the lines). The only lines that still showed a low resistance were the Coil lines. |

The bigger leak found on MSP before was gone. Leak rate are smaller on all circuits comparing to before.
The leak rate on 1 hour total lines test at 70 psi is better also which is 6.6 XE-8 atm.cc/sec this time. |
Friday, May 20, 2016, 08:13, David Wang, Conditioning Station, Standard Operation, TM2, Ta#48, I switched off TCS and TM2 water system
|
Disconnected TM2 at TCS(vacuum system still on). Purged all TM2 water lines for helium pressure test. |
