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. |

Monday, October 17, 2022, 08:07, David Wang, ITE/ITW, Repair, TM4, , A small leak on target station secondaryvacuum back up line by ITH MP1S.
|
A small leak in target station secondary vacuum back
up line is observed. It affects ITH CG2S,CG1S and CG4SA. Current draw on TP1s and TP4S is getting higher(above 1A) because of it. An internal leak in
ITH MP1S is suspected by first round investigation. Close watching on system and further investigation are needed.

|
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, |

TM4 was moved from ITE to NHC with C#4. |
Tuesday, November 22, 2022, 12:41, Frank Song, North Hot-Cell, Standard Operation, TM4, C#4, electrical check
|
TM4 with C#4 is checked on NHC right after moving from ITE. |
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. |

|
an electric check and leak check done on NHC, TM4 with new target UCx#41 is ready moving to TCS. |
Wednesday, November 23, 2022, 12:10, Adam Newsome, Conditioning Station, Standard Operation, TM4, UCx#41, TM4 Move - NHC to TCS
|
TM4 was moved from the North Hot Cell to the Target Conditioning Station with UCx#41. |
Thursday, November 24, 2022, 11:32, Adam Newsome, Spent Target Vault, Standard Operation, TM4, C#4, C#4 Spent Target Moved to Storage Vault
|
C#4 spent target was moved to the storage vault, in pail 277. Dose rate at approximately 1 m when leaving the hot cell was 164 mSv/h. The pail has been
placed in vault location 4C. See updated vault layout attached. |

|
TM4 with UCx#41 was connected in ITE on Tuesday (2022-11-29) |
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. |
Tuesday, January 24, 2023, 07:17, David Wang, ITE, Standard Operation, TM4, UCx#41, TM4 water lines helium pressure test 2023.
|
TM4 water lines helium pressure test was done yesterday at ITE. All water lines were air purged one day ahead for the test. No leak has been
found on TM4 waterlines during the test. See attachment for detail |
Tuesday, January 24, 2023, 08:46, David Wang, ITE, Standard Operation, TM4, UCx#41, TM4 has been disconnected in ITE.

TM4 electrical check with UCX41target and without target at SHC. The results are good. See attachment. |
Wednesday, January 25, 2023, 06:52, David Wang, ITE, Standard Operation, TM4, UCx#41, ITE primary and secondary vacuum vessel air to vacuum seals leak check.
|
ITE primary and secondary vacuum vessel air to vacuum seals leak check was done this week. One leak has been found on IG1S feed through to entrance module
surface seal. It explains what we saw on ITE IG1S readings change(from low E-7 torr to 1Xe-6 torr) on December 22, 2022. This leak seal will be replaced
soon. |
