Tuesday, May 02, 2023, 17:18, David Wang, ITE, Standard Operation, , , ITE 4 turbopumps are started for preoperation check.
|
ITE TP3,4, 1S,and 4S were started successfully this afternoon. All pump current draws were below 1.5A . IG1S was switched on. I have no local controller
so TP1 and TP2 on TM4 at MSP can not be checked. IG1S was hard to switch on at first. It timed out and showed error 09 code. I removed the
connector back cap, and it could be switched on after. I will look on this issue. |

Monday, June 12, 2023, 07:36, David Wang, Conditioning Station, Standard Operation, , , TCS water filters annual change.
|
Plant group changed TCS water filters last Friday. 4 filters on resin can inet /outlet sides and filters(4 in one cartridge house)on pump return line
have been changed. Triumf maintenance tags on filters have been updated. No water leak after job. The TCS TK2 water level dropped from 20" to
16" because of the job. I will refill the level to 28" today. |

Tuesday, June 20, 2023, 12:37, Adam Newsome, Assembly/Bench Test, Development, , , Modifications to wire ropes for pails within existing F-308s 6x
|
Based on a request from CNL (attached), modifications were made to the wire ropes protruding through the tops of F-308s to add a crimped loop which acts
as a lifting feature. Tests were performed (report attached) on 10 sample units to validate the strength of these loops, since each loop could not be tested
in-situ once the pails were already packed in F-308s. CNL has reviewed and approved the test report. |

Wednesday, July 12, 2023, 22:21, Carla Babcock, North Hot-Cell, Standard Operation, , TiC#5, TiC#5 post irradiation inspection results
|
The TiC#5 post irradiation inspection was done on Wed. June 14 and Mon. June 19. This target didn't have any obvious issues but it didn't produce much
beam. The inspection revealed that the container was quite embrittled and showed significant damage, though it was not broken. The FEBIAD grid looked fine,
despite the large anode current draw (indicating that current was flowing elsewhere). The gas line looked fine though the gas injection to this target |

Tuesday, July 25, 2023, 16:25, Carla Babcock, North Hot-Cell, Standard Operation, , SiC#45, SiC#45 post irradiation inspection
|
Looked at SiC#45 in the hot cell. Looked very clean, no deposits on the heat shield or other components. Target also looked very straight. Only issue
we saw was sparking marks on the EE side that faces the ground electrode, in several spots. This target had a bout of sparking when ramping up the protons,
so I guess that was the location. Will look for matching spark marks on the ground electrode next time TM4 is in the hot cell. Forgot to take picutres... |

|
Bearings for the main storage vault door were lubricated on 2023-07-28. It is unknown when this was last done. It is suggested that this be a recurring
maintenance task every two years. |

The bearings on the mini storage vault were lubricated. It is suspected that this has never been done. It is suggested that this be performed every two
years.
A draft procedure will be created for this job, but at a high level, this process involves: |
