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. |

|
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. |

|
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 |

|
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 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 |
