On 26/Sept/2022
Chad disassembled the right operator side manipulator, and noticed that gears in the handle were quite tight especially when compared to the left
operator side manipulator. |

|
Myself and Maico were able to top up the NHC window oil.
The oil was filled through the expansion tank
- the Nitrogen line closed and the Nitrogen pressure valve was disconnected to ensure that no oil would go in to them. |

Monday, October 03, 2022, 14:58, Matthew Gareau, North Hot-Cell, Repair, TM4, SiC#43 and C#4, Loose multipin guide pin
|
Today while I was removing the SiC#43 it was noticed that the multipin guide pin was loose.
This made it difficult to remove the target, and the multipin shoulder bolts removal was required.
With the loose pin it was not possible to attach the multipin for the target C#4. |

|
Conducted PIE on SiC#44, which failed online. It had a cathode short, a target short and an anode short by the time we called the experiment off. In
the post irradiation examination, two clear marks where the target legs touched the heat shield were found (see attachments 1 and 2). No marks were found
to indicate where the cathode short would have been. The fibreglass sheath covering the anode wire where it passes over top of the coil was destroyed, |

|
TM2 with spent target UCx#39 had an electric check in NHC.
After UCx 39# target was removed out., I did electrical check on TM2. @500 V B to C is 5M ohm. all Others between are above 25Mohm.
HV to Chasis is 650Mohm. A to P is still short. |

Did the PIE on UCx#39-IGLIS on Thursday Nov. 2 2022, couple pictures uploaded to docushare. Did not remove the target, just the heat shield cover.
Final electrical check on the module showed a dead short from TGHT/TBHT to HV common, which we did not see online. Seems like it must have occurred
after ramp down? It persisted on the target after we removed it from the module. We couldn't find any obvious contact points, because it seems it did not |

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. |

Thursday, December 01, 2022, 13:45, Carla Babcock, North Hot-Cell, Standard Operation, TM4, C#4, Post irradiation inspection C#4
|
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. |

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". |
