David Wang | Conditioning Station | Standard Operation | TM4 | UC#16 | TM4 UCx16 electrical check and leak check at SHC |
Chad and I finished the TM4 UCx6 electrical check and leak check at SHC. Leak check result on HS line is good. There is a dead short between "Z" repellor and HS during the first time electrical check. The dead short disappeared after re- installation of UCx 14 target onto TM4. See attachment
Anders and I did another electrical check on TM4 at TCS under vacuum. See attachment 2 |

David Wang | South Hot-Cell | Standard Operation | TM4 | Ta#47 | electrical check on TM4 with old Ta target at SHC. |
I did an electrical check on TM4 with the old target still installed. The number is a little bit low on 500V mega check between chassis and 60KVbias which is 146Mohm. Others are good. See attachment
I wrote all OL to 0 in attachment 1 ohmmeter check. Please See attachment 2 for correction. |

See attachment for sparking signs of the water lines mentioned above (Coil and Ground Electrode lines) in TM3 Source Tray.
|
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. |
