Frank and I replaced ITW Exit module 1 side square service panel o-ring seal. Also, The target module pit top flange o-ring seal in ITW pit is replaced.  

  Carla did the test. and reported the result as following: HV testing of ITW is complete. It was pretty well behaved up to 59.5kV, and sat at 59kV for 30mins with no sparks (that EPICS caught). There was some strange behaviour of the current between 51kV and 53kV - it was jumping by 20uA or more - but there didn't seem to be any voltage response, and it went away after 53kV (though it returned on the way back down). The test was done in Feb 02.

 TM2 was connected in ITW with a Febiad Test Target. 

Annual ITW water signal interlocks check was done with TM2 in ITW.   Water signal interlocks on all water circuits related to TM and 2A beam lines in ITW work fine. 

 TM2 with a test target was disconnected in ITW.

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

 the module was disconnected in pit and moved to NHC.

 TM2 with Target UCx#38 was connected in ITW.

 TM2 with Target UCx38 was disconnected in ITW and moved to NHC

 TM2 with UCx#39 is connected in ITW.

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

 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.

 ITW  was cleaned with vacuum canister in Jan 10th. HV  cage inside and blue nylon insulators were wiped.  Garbage inside the pits were cleaned out.

In past two weeks, ITW/ ITE primary vacuum back up lines and BVs in ITW/ITE pit have been leak checked.  ITW BV1 and BV2 on back up line side were leak. They are replaced with old leak free BVs.  ITE TP2 NW25 SST  flexible line right after pump were leak . It is replaced with new NW25 SST flexible line. Two leak were found on ITW side KF 50 O-rings connected to NW 50 SST flexible coupling. They were replaced with new KF50 o-rings. After job, both  stations primary back up lines in pit were leak checked .  They are good.

 TM2 with TiC#6 was connected in ITW (FEBIAD), turbo pumps were started successfully.

 Gas lines pumped down at electric room for TM2 at ITW is done, leak rate 0.0e -8 <1.0e -3 T P pressure

ITW water signal interlock check is done. All ITW water signals including HS, EE, Coil , Ta, Tu, MSP, C-window, HVC1, HVC2, 2A-dump, 2A -shielding plug, 2A-tank, 2A-window, and 2A-collimator are checked. All  water signal interlock work fine.

Conditioned TM2 up to 48kV in ITW. Some sparks and current is not very stable. Drawing about 178uA at 48kV.
