 Wednesday, August 01, 2018, 15:12, Anders Mjos, South Hot-Cell, Standard Operation, TM2, UC#23, Target mounted - water leak on HS line 
|
The heat shield water lines were not purged ahead of target exchange in the hot cell. This resulted in water leaking onto the new target assembly (heat
shield) when the cooling lines were opened at top and bottom (for connecting leak detector). Excess water was wiped up with paper towels. |

|
Both the West Entrance and TM#2 with UC#23 have been moved back into their places in the west target station. The Entrance module move wasn't completely
smooth as it did suffer a little bumpiness when the shield plug part was installed, I was lifted back out again and no visible damage was observed on the
delicate items. |

Monday, September 24, 2018, 10:21, Anders Mjos, South Hot-Cell, Standard Operation, TM2, UC#23, Post Irradiation Examination (PIE)
|
UC#23 experienced short between target and heat shield as it was heated during operation. The inspection of the target after irradiation revealed that
the left target leg was close to the heat shield opening and likely the cause of the short. Marks could be seen on the leg indicating contact. See attached
photo. More photos are available on DocuShare |

|
On September 18th installation of nSiC#1 was attempted on TM2. As usual, new fasteners were tested previous to insertion into hot cell and employed during
installation. the last fastener to be installed was for the circuit D block. The fastener/air ratchet stalled immediately indicating a problem. The fastener
was removed and a an attempt was made trying a new spare fastener. That fastener also jammed right away but could not be removed or installed any further. |

Thursday, November 01, 2018, 11:42, 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. |

|
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. |

TM2 was connected yesterday by Frank and Anders. The West side panel with IG1S on Exit Module 2 was replaced with a new SST panel with 1 CF flange only
(dwg). Link to check list on DocuShare. |

Wednesday, November 14, 2018, 16:10, 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. |
