  2329   Thursday, June 09, 2022, 09:47 Matthew GareauSouth Hot-CellRepairTM2SiC#42containment box repair, Einzle lens, multi pin

On June 2 2022, while attempting to install target SiC#42 a gasket fell off the water line. I attempted to remove the target to have the gasket reattached, however the multi pin connector guide pin was loose and was preventing the target from being removed. During the attempt to remove the target it was noticed that an electrical cable in the back of the module had become loose and was dangling. The target was then secured to the module, and then the module was moved to the SHC to complete the job/repairs.

June 3 2022, containment box was removed, Einzle Lens cable reattached and tested, and the multi pin guide pin was retightened.

On June 6 2022, the containment box was damaged while lifting the containment box back onto the module.

The left rear corner of the box caught on the module and the corner weld snapped and folded the corner down about 90 degrees.

With help from Chad, we were able to restraighten the corner with a C-clamp, enabling the box to be reattached to the module.

However the 2 bolts that were on the corner that attach to the module were not able to be aligned and were not used.

The target was reattached to the module, and to save time was brought directly to ITW, skipping the conditioning station.

  2332   Tuesday, June 21, 2022, 15:36 Matthew GareauNorth Hot-CellRepairTM2SiC#42, SiC#43multipin guide pin issues

 While removing the SiC#42 it became apparent that the multipin guide pin had become loose again and was not allowing the target to dismount from the module.

The multipin shoulder bolts were removed and then the multipin was able to be pried off.

However the NHC manipulator were not able to reach the guide pin to remove it, which would be required before the SiC#43 could be installed.

The target module was then moved to the SHC where the guide pin could be removed and the installation of SiC#43 took place, along with the transfer of the parasitic attachment onto the SiC#43.

This problem seems to suggest that the multipin could use some redesign to ensure smoother target exchanges.

Monday morning June 20th: TM2 with SiC # 42 was moved from ITW to NHC.

Monday afternoon: TM2 with no target was moved from NHC to SHC due to 10 pin connector guide pin loose issue. The guide pin has to be moved out in SHC due to NHC manipulator configuration limit .

Monday afternoon: TM2 with SiC # 43 was moved from SHC  to ITW.

all module moves are smooth.

  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.
