David Wang | Conditioning Station | Standard Operation | TM2 | UCx 25. | TM2 HS line helium pressure test at TCS and helium spray at SHC.. |
Chad and I did leak check on TM2 HS line at SHC yesterday. Base LR 0.0XE-9 atm.cc/sec. No response on LD. during helium spray. Today , I did helium pressure test at TCS. base LR 0.0xe-9atm.cc/sec. applied 70psi helium for 3 minute. leak rate slowly climbed to2.2 Xe-7 atm.cc/sec ate stopped there. The result is close to before. |

Anders Mjos | Conditioning Station | Standard Operation | TM2 | UC#25 | Target module disconnected |
Frank and Anders disconnected the water and electrical connections this afternoon after the target was conditioned over the weekend. The heater ramping program ran with the wrong gauge selected, causing the vacuum to go higher than planned. The module will be moved to ITW tomorrow. |

Anders Mjos | ITW | Repair | TM2 | UC#25 | ITW:FC5 safety signal troubleshooting |
Measured resistance on safety limit switches for FC5 on Exit Module 2. Determined that the in connected signal did not work (shows not connected irregardless of FC position). Confirmed proper operation of the OUT limit. See attachment for details. The Harp 5 x and y signal connectors were checked and reconnected. |
