TM4 has been moved from SHC to TCS. No target on module. The move is successful.

UCx#29 has been removed from TM$ and placed in a pail backfilled with argon until it can be moved to the storage vault.

 TM#4 with UC#29 has been moved from the west target station to the south hot cell.

TM4 has been disconnected in ITW. See attachment checklist.

ITW is argon venting now.

Argon venting of ITW is done. It took about 4.0 to 4.5 hours to vent the ITW with 2-3 psi argon. The CG4 and CG4S showed 35 to 36 torr on epic page when mechanical gauge is 760torr in electrical. Argon gas bottle is closed in electrical room.

Connected LD to ITW(TM4) TP1. Base LR 0.0Xe-9 atm.cc/sec. Base pressure 0.0Xe-4 torr. All ITW primary and secondary air to vacuum seals are helium spray checked. There is a 5XE-9 atm.cc/sec leak on  exit2 module top cover plate o-ring seal. The location is on west  side, south corner of the plate. Hi- vacuum resin are sprayed to leak area, and leak checked  again. The leak is gone.   The other seals on ITW vacuum vessel are good.

  TM4 internal water lines helium pressure leak check at ITW : 70psi helium 5 minutes on  each circuits. Base leak rate 0.0X E-9 atm.cc/sec. Base pressure 0.0X E-4torr. Only B line(Oven -) has a tiny 1.5Xe-9 atm.cc/sec response on LD during the check . All others all perfect good. 

Leak check on ITE vacuum vessel is done. LD base leak rate 0.0XE-9atm.cc/sec. base pressure 0.0Xe-4torr. Sprayed helium on all ITE primary and secondary vacuum vessel seals(including TM2). No leak . Also,70psi helium  pressurized TM2 waterlines inside the module for each circuit 3 minutes. No leak on all operating TM2 waterlines.  

With both stations in operation,ITE dump supply gauge reading is 27 psi. ITW is 20 Psi.  I adjusted ITW dump pressure to 25 psi by changing the return line side pressure relieve valve.

ITE full operation+ ITW no TM: ITE dump pressure 27psi, ITW dump pressure 27psi.

2019-01-30: Water only supply to 2A beam lines only on both side, No TM2 and TM4 in water loop.  ITE dump pressure 27psi, ITW dump pressure 27psi.

ITW water signal interlock check is done. Everything works fine. ITW 2A2 tank water signal is broken and is not ok on XT2A2  page. I will fix it next week.

 TM#3 has been moved from the conditioning station to the centre east silo.

TM3 TP1 and TP2 work  fine in past 4 days. During operation, The current draw on pumps were 0.7A to 0.8 A. TM3 will be moved back to silo tomorrow.

Using a long pole with a probe to spray helium on TCS vacuum seals and joints which are installed in  TCS service pit. No response has been found on leak detector during leak check. TCS is leak free.

 Targeta Ta#49 and Ta#52 have been repackaged anf moved to the mini vault. Ta#49 was taken out of pail number 146 and placed into pail 229. Ta#52 was taken out of pail number 152 and placed into pail 230.

ITE water  signal interlock   check is done.  Everything is good. It is a annual check we do in winter shut down time.

I started TCS roughing pump. TM3 TP1 and TP2 will be started tomorrow morning.

 TM#3 has been moved from the south west silo to the conditioning station.

The second module lifting assembly ITA0490 is moved into TH and installed onto TM3 . It will stay with TM3. I adjusted the  CofG on the assembly. It is same to the first lifting assembly we are using now. After adjustment, The installation of assembly on TM3 are smooth. 

5 shielding blocks are moved out of itw top.

HALCW MP2 is switched on this morning after yesterday cooling tower maintenance. LALCW P5 and P6 pumps are started by isac operator  as well. The system is good so far.
