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. 

Once a dry grease was added, and the handle reassembled all seemed to be in working order.

There was noticeable wear on a shaft and Chad has suggested to order some spare parts for the wrist and handle.

 The spent target UC#38 was packed into pail #274 and placed in spot 1A of the vault. It was 33.3mSv/hr when removed from the north hot cell. See attached PDF for more vault details.

  2366   Wednesday, September 14, 2022, 13:45 Adam NewsomeSpent Target VaultDevelopment  Storage Vault: cable replaced and e-chain upgrade

The motor cable for the storage vault was replaced as the old one was showing signs of wear. The U-track that the old cable ran through was also bent as a result of being hit.

In the process of replacing the cable, an e-chain was installed for cable management purposes. Mounting brackets were modified and a new U-track was installed as well. The new hardware is more robust than what was previously installed.

The vault door was opened and closed multiple times while observing the e-chain - everything behaved as expected. The system is operational.

 

Solidworks model IRH0189 is updated to show the changes

ITE:ANODE supply reading strange currents - 17mA with the power supply on and no voltage. Checked anode circuit from electrical room:

Anode wire in electrical room shows 0L at 250V

Circuit with 50kOhm resistor mostly looks good (49-52kOhms) but a couple times read 28kOhms, no idea why. Tried jiggling all cables, unplugging and replugging and everything looks fine.

But power supply still seems to be giving out signal for 17mA readback. Decided fastest to swap with TCS power supply and troubleshoot this one on the bench.

TM4 with SiC#44 installed developed a short TBHT to HV common during its first heating in ITE. Was fine before installation. Now with everything cold TBHT to HVC is 25kOhms. Removed short in electrical room, will rely on short in the module.

  2352   Friday, July 29, 2022, 12:05 Carla BabcockNorth Hot-CellRepairTM2UCx#38Repair of UCx#38 EE short in ante room

UCx#38 developed a short between the plasma electrode and the extraction electrode about 30mins after reaching full temperature in the conditioning station. The decision was made to bring it into the anteroom and try to clean it there.

To do this, it was uninstalled, the parasitic attachments were removed and it was brought into the ante room.

I removed the EE and the PE, and cleaned quite a lot of material from them both with methanol. I think put the ionizer foil bar down the ionizer to help dislodge any material there, and I also turned the target over and tapped gently to get any material out. The first two times some flakes came out, the third time nothing came out. I then reinstalled the electrodes using the EE alignment tool (not sure how successfully, didn't push it into the ionizer too much because I was worried about catching the Rh foil).

The taret was meggered at 500V then reinstalled and electrical checks were done. Everything looks back to normal. Conditioning in ITW was successful.
