A electrical check was done at NHC, see the pic attached with please.

 A electrical check was done for TM2 with UCx#38

 A standard electrical check was done for TM2 after the short issue be fixed.

 TM2 with Target UCx#38 was connected in ITW.

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 Target UCx38 was disconnected in ITW and moved to NHC

 An electrical was done on the NHC for TM2 with spent Target UCx#38 on

 An electrical check was done on NHC yesterday.

TM2 with UCX#39 HS line helium pressure test is done at TCS. 70 psi helium 3minutes. No leak @0.0XE-9 atm.cc/sec.

 TM2 with UCx#39 is connected in ITW.

 TM2 with spent target UCx#39 was disconnected in ITW then moved to NHC.

 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.

an electrical check was done on NHC, TM2 with new target UCx40 is ready moving to TCS.

Helium 70 psi. tested 5minutes at base leak rate 0.9 xE09 atm.cc/sec on HS line.  No leak.

 TM2 with UCx#40 is connected in ITW.

ITW and TM2 primary and secondary vacuum vessel leak check is done. Leak detector is connected to ITW TP1. Base leak rate on leak detector is 0.0 x E-9 atm.cc/sec.   See attachment for the result.  No big issue. Two old leaks we found last year at location D and E disappeared in this check. We did Vacseal resin spray on them last year.  It looks like the Vacseal spray works .  From the result , I can see the o-ring between exit 1 module and T - flange is closing to the end of the life.  There are two small leaks on this o-ring now at A and B location. We plan to change this o-ring next winter shut down. We do vacseal spray on them this year. The big O-ring between tank vessel and T -flange looks still ok. Two small leaks are found on location F and G on this O-ring. Not much we can do on them. The leak on location C and B were sprayed with resin yesterday after leak check. They are leak free after spray on check. I will double check them. Leak on location A will be resin sprayed after TM2 is removed and ITW is under vacuum.   All TM2 internal water-cooling lines are helium pressurized (70 psi) for 5 minutes each. HS shows 2.5 X E-9atm.cc/sec leak rate. The rest lines are 0.0 X E-9 atm.cc/sec.

 TM2 with target UCx40 was disconnected in ITW and moved to NHC.

 TM2 with no target on SW silo be electrical checked right after module moving.

 TM2 with TiC#6 was checked on SHC, see pic attached pls.

TM2 HS line helium leak check is done. leak detector base LR 1.8xE-8atm.cc/sec.  helium pressure 70 psi. 5 minutes test. no change on LD leak rate.    I spray lots helium to gas line adaptor and fittings. No leak.has been found  at this base leak rate level.  Since the TCS MP1 has some  issue ,this time the base leak rate on LD only can get to 1.8Xe-8 atm.cc/sec at this moment instead of 0.0xE-9.  The low E-8  level is not perfect, but  i  have no concern on it.
