TM2 was disconnected in ITW yesterday and moved to SHC.

Chad and I leak checked Tm2 Hs line with new target installed. Base LR 0.0Xe-9 atm.cc/sec.   No leak has been found. This line will be helium pressured at TCS later.

Start of roughing now.

I did a helium pressure test on TM2 HS water line at TCS. Leak detector base leak rate only could get to 1.8x e-8 atm.cc/sec at this moment. Applied 5 minutes 70psi helium on it. No leak has been found at this level. I connected water to this circuit after the test for weekend TM2 conditioning at TCS.

I will do another helium pressure test after the conditioning. The LD base leak rate should be 0.0Xe-9 atm.cc/sec at that time.

2016-08-29: LD Base leak rate 0.0xe-9atm.cc/sec.TM2 HS line helium pressure check again after conditioning. 70psi helium 5minutes. no response on LD. HS line is perfectly sealed.

The HV cover is installed. The Faraday cage at B2 level is locked also.The TCS and TM2 are still pumping down. Everything is good so far.

Weekly update schedule.  See attachment 1,2.

I stopped TCS water pumps and vacuum pumps also.   TM2 and TCS will be vented tomorrow morning.

  ITW turbo pumps  have been started.

5shielding blocks have been transferred from ITE to ITE. ITW is configured to take proton beam.

All TM3 blue insulators except Gas,EL, and 60 KV common  on top of the module have been replaced with new designed insulators. The new blue insulator for gas line need to be modified to fit for the bent on the gas  line.   EL, and 60KV common blue insulators were replaced during last time TM3 refurbishment so they are relative new, and  not replaced this time. All seals related to the blue insulators are changed to new seals. The o- r-ing surfaces  for o-ring 221 inside the  new insulators  are rougher than old parts. The module top need to be leak checked.

start of roughing now.

 start of TCS and TM3 turbo-pumps. Everything is good so far.

After blue insulators replacement, TM3 service cap are leak checked. LD base leak rate 0.0xe-9 atm.cc/sec. I sprayed lots helium on all blue insulator seals. No leak has been found. Double checked them again, and got same result. All other seals on top of TM3 also have been checked. They are leak free. OVEN, TUBE, MSP, COIL, and EE water lines are pressurized with 70 psi helium for 3minutes each. They are good also.

 TM3 is disconnected at TCS and ready to be moved to silo.

Post new  target hall Excel sheet schedule for beam schedule 131. See attachment 1,2

Post new target hall  MS project schedule for beam schedule131. See attachment 3,4

TM4 has been disconnected in ITE. No water line purge on HS and 3 water circuits are looped after disconnection. The HALCW system resistivity is stable before and after this disconnection.

A silo and blue steel frame are removed out of TH this morning. They are transferred  through ante room, and moved to experimental hall TM assembly area for a long term storage. Swipes are done on the silo and frame before and during move. No contamination has been found .

Chad and I leak checked the TM4 HS line after new target installation. base leak rate:0.0Xe-9 atm.cc/sec.  No response on LD during the leak check. The line is leak free so far. It will be helium pressurized at TCS  late.

All TCS and TM4 turbo-pumps were started yesterday. Overnight pumping down is good so far.

TCS water system and vacuum system are turned  off this morning. The TCS and TM4 are vented.

All ITE turbo pumps have been started since yesterday afternoon. The ITE and TM4 pumping down is good so far.
