Shorted TGHT with new high current connector assembly and heated to 600 A. Temperature measured on half way point on cable ~ 70 deg C and on connector
~60 deg C at 600 A, 45 / 40 deg C at 400 A. Target Hall locked out during test |

|
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 |

Monday, July 16, 2018, 17:41, Anders Mjos, ITE, Standard Operation, TM4, UC#22, Target module disconnected
|
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 . |

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. |

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. |

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 |

|
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. |

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. |

|
Blocks were moved from ITW to ITE by Frank and David. ITE water flow to dump was re-opened (ITW remains open). A dose badge was installed in the operation
storage area. Dose rates were measured to ~10 mSv/h at 1pm. Beam went off approximately 8:30am (with a short period of 2uA ending at 11am). |
