Tuesday, November 22, 2022, 14:53, Carla Babcock, North Hot-Cell, Maintenance, TM4, , Multipin connector alignment pin on TM4 module loose
|
The pin on TM4 has become loose again, making it very difficult to remove the multipin connector with the last target, C#4. For the installation of the
next target, UCx#41, we will drill out the hole on the target side bracket so that it doesn't contact the multipin pin. Will try to remove this pin by
force in January, or if needed change out the whole multipin bracket. |

|
Post irradiation inspection of C#4 which was running in TM4/ITE was conducted at the NHC on Nov. 22 2022.
The yields from this target had been dropping and its behaviour was erratic, with the voltages on the tube and target jumping all over the place
sometimes. The ion current on the FCs followed the voltages. We took this to mean the target container was breaking down. |

|
The linear actuator used for the Y-motion motor assistance on the spare telemanipulator was replaced and tested. It was observed around September 2021
that the former one which was installed was causing fuses to blow for the main 120 VAC power supply in the control box. After some troubleshooting, it
was determined that the linear actuator itself did not operate smoothly - it was suspected that this caused motor overload due to additional friction. |

NHC is 1.26 mSv/h inside approximately .5m from table surface, between manipulators
SHC 186 uSv/h inside approximately .5m from table surface and between manipulaotrs |

The fields in the NHC after removal of Ferran's graphite sample is 238 uSv/h. This again seems to emanate for the items in the 5 gal pail...the copper
tubing from the beam window or, as I mentioned in my previous elog, the peek samples. I did ask about removing these during the graphite sample removal
but was told they were not "hot". |

NHC was entered on April 17, 2023 for inspection and maintenance. Summary :
Compressible and non-compressible waste was loaded into a 55 gal drum and removed from the NHC. This same drum will be inserted into the SHC at
a later date to be sorted, compressible waste compressed, and drum filled more. |

|
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 |

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... |

|
PIE on TiC#6 was done in the NHC. The target assembly looked brand new when we took it out, no heating spots or deposits (pictures on docushare). Online
we measured a 400kOhm connection between TGHT-TBHT-COIL to HV common (TGHT and COIL shorted in TM2 service tray) and anode was unstable above ~300V. After
the module move and before the target removal David found TGHT-TBHT-COIL was a dead short to HV common and the anode was at 39kOhms to HV common. |
