Last Friday July-15, TM3 was leak checked at TCS. All air to vacuum seals on service cap are good.  Helium pressure test on  TM3 water lines(except GE, HS, and Window) were done. Leak detector has no response at 0.0xE-9 atm.cc/sec. They are leak free.

I started vacuum system.

I started TCS water system. The chiller does not work properly still. But, It will not affect the TM3 HV conditioning.  HV cover is installed on TM3 in TH. The module is ready for HV conditioning.

It is being pumped now at TCS.

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.
