|
Dan and I connected TM4 in ITE yesterday. It is pumping down at ITE now. Everything is fine so far. |
|
Thursday, August 11, 2016, 10:37, David Wang, Conditioning Station, Repair, TM3, , TM3 service tray cover plate ITA2108 has been removed.
|
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. |
|

|
Weekly update target hall schedule. Everything on schedule are finished on time. See attachment. |
|
Tuesday, August 16, 2016, 12:35, David Wang, Conditioning Station, Repair, TM3, , CS vacuum pumps have been stopped
|
The TCS is venting now. The TM3 blue insulator replacement job will be started soon. |
|
Wednesday, August 24, 2016, 10:41, David Wang, ITW, Standard Operation, TM2, , TM2 was disconnected in ITW yesterday.
|
TM2 was disconnected in ITW yesterday and moved to SHC. |
|
Wednesday, August 24, 2016, 10:44, David Wang, South Hot-Cell, Standard Operation, TM2, , SHC, TM2 leak check on HS line.
|
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. |
|
Wednesday, August 24, 2016, 10:45, David Wang, Conditioning Station, Standard Operation, TM2, , TM2 vacuum system has been connected at TCS
|
Start of roughing now. |
|
Thursday, August 25, 2016, 08:36, David Wang, Conditioning Station, Standard Operation, TM2, , Helium pressure test on TM2 HS water lline
|
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. |
|
Thursday, August 25, 2016, 08:43, David Wang, Conditioning Station, Standard Operation, TM2, , All TM2 connections to TCS are done.
|
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. |
|
Monday, August 29, 2016, 13:34, David Wang, Conditioning Station, Standard Operation, TM2, , TM2 has been disconnected at TCS
|
I stopped TCS water pumps and vacuum pumps also. TM2 and TCS will be vented tomorrow morning. |
|
Tuesday, August 30, 2016, 13:17, David Wang, ITW, Standard Operation, TM2, , TM2 has been connected at ITW
|
ITW turbo pumps have been started. |
|
Tuesday, September 06, 2016, 10:05, David Wang, ITW, Standard Operation, TM2, , 5 Shielding blocks have been transferred from ITE to ITW.
|
5shielding blocks have been transferred from ITE to ITE. ITW is configured to take proton beam. |
|
Thursday, September 08, 2016, 16:28, David Wang, Conditioning Station, Repair, TM3, , TM3 blue insulators have been replaced.
|
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. |
