 TM2 with new target SiC#43 was electrical checked at SHC. please see attachment.

  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.

 TM2 with Febiad Target SiC #43 was connected in ITW. NOTE: the number of TARGET in attached picture should be #43. 

  2337   Wednesday, June 22, 2022, 09:14 David WangSouth Hot-CellStandard OperationTM2SiC#42 and SiC#43. Three of TM2 moves related to SiC#42 to SiC #43 target switching job.

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.

 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.
