|
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. |

The spent Nb#8 target was moved from the south hot cell to the spent target vault. It was placed in pail #168 and place in spot 2A in the vault.
See the attached pdf for vault details. |

Thursday, August 02, 2018, 07:57, David Wang, Conditioning Station, Standard Operation, , , Leak check on TM2 UCx #23 @ TCS and SHC.
|
I did a helium pressure test on TM2 HS line at TCS. At 70psi helium, the leak rate is 2.5 xE-7 atm.cc/sec. I think this is the number that close to result
before which is 1.7xE-9 atm.cc/sec. WE know there is a small leak on this water block seal. Chad and I did helium spray check yesterday at
SHC. It was good at bottom scale. No much worry on this low E-7 range leak. |

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. |

Wednesday, August 01, 2018, 09:47, Isaac Earle, North Hot-Cell, Development, , , NHC diagnostic signals and control panel tested
|
On July 30th the NHC diagnostic signals were tested:
- 9 pin CPC: a shorting plug was installed on the hot side - continuity check results were as expected
- 4 pin CPCs: snake camera installed in both hot side connectors with portable monitor on cold side - both connectors worked as expected |

Wednesday, July 25, 2018, 13:21, Anders Mjos, ITW, Repair, TM2, Nb#8, Leak check of ITW
|
ITW Entrance Module was leak checked yesterday with the support of Vacuum Group (Dimo & Edi). The leak detector was connected to primary backing
vacuum line. A leak response was found near the bellow for the beam profile monitor on top of the Entrance Module. It could be confirmed today by actuating
the monitor, that the leak was indeed at that location. The plan is to move the TM and Entrance Module out for target exchange and repair, respectively. |

|
Installation of the diagnostic connections between the NHC hot and cold sides has been completed. The cable bundle was prepared by Travis Cave
in the electronics workshop with connectors attached at one end only. Metal fish tape was first ran through the conduit from the cold side to hot
side, the non-terminated end of the cable bundle was attached to the fish tape inside the cell, cable pulling lubricant was applied, then the cable bundle |

The water and electrical connections were disconnected today as protons remained off after power interruption during the weekend. Vacuum is still connected
and operating.
The vacuum system are disconnected 2018-07-17. See attachment . |

|
The 2A2M19 beam profile monitor did not work and was e-faulted.
After initial troubleshooting 2 blocks were removed form ITW to inspect the entrance module where the beam monitor is installed. The cable was found not
to be connected and was quickly fixed. Blocks reinstalled. The work was done by Maico, Travis and Anders |
