Helium pressure test on TM4 HS line at TCS  is done.Leak detector 0.0X E-9atm.cc/sec.  5minutes, 70psi helium.    No response on LD.

I started TCS water system and installed HV cover onto TM4.  The TM4 containment box is supplied with water also. TM4 is ready for conditioning at TCS.

Update schedule weekly. See attachments 1,2

I stopped TCS water pumps this morning . The argon venting for TCS is in processing.

Dan and I connected TM4 in ITE yesterday. It is pumping down at ITE now. Everything is fine so far.

Requested by Aurelia, and approved by Friedhelm, TM3 service tray cover plate ITA2108 has been remove out of the module. The plated is checked for active and contamination after removal. Then,It is double bagged, sealed ,  tagged, and placed downstairs in TH between south wall and green block . The ram contact reading on the plate is about 10 usv/hr.  We will do anther TM3 HV test at TCS without this cover plate.

Dan and I transferred 5 shielding blocks from ITW to ITE. The ITE is configured to take proton beam.

Weekly update target hall schedule. Everything on schedule are finished  on time.   See attachment.  

The TCS is venting now. The TM3 blue insulator replacement job will be started soon.

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.
