|
Friday, September 08, 2017, 14:08, David Wang, Conditioning Station, Repair, TM3, , TCS and TM3
|
TM3 is located at TCS and it is pumping down now. TCS water system has been started. All TCS water lines for TM3 module internal cooling are bypassed and looped at TCS top ground plate. Water only supply to TCS high current conductors. |
|
Wednesday, September 13, 2017, 10:05, David Wang, Conditioning Station, Repair, TM3, , Switch off TCS water system and vacuums
|
Preparing vent the TCS/TM3. We will remove TM3 service tray cover plate after venting. |
|
Wednesday, September 13, 2017, 16:05, David Wang, Conditioning Station, Repair, TM3, , remove Tm3 service tray cover plate
|
TM3 service tray cover plate has been removed. It is bagged and placed to TH b2 level south wall beside the silo. |
|
Wednesday, September 13, 2017, 16:13, David Wang, Conditioning Station, Repair, TM3, , TCS turbo pumps are started.
|
TCS and TM3 all vacuum pumps are started. Everything is fine. |
Friday, September 22, 2017, 12:13, David Wang, South Hot-Cell, Maintenance, TM2, , TM2 service cap inside inspection. 
|
Two side panels on TM2 service cap were removed for TM2 service cap inside inspection. A piece of cable tie was found inside cap closing to service tray entrance area. All blue nylon insulators are inspected. They look good. The broken cable tie is moved out of service cap.
Panels are installed back after the inspection.

Thursday, September 28, 2017, 10:50, David Wang, Conditioning Station, Standard Operation, TM2, , Helium pressure test on TM2 window and HS water lines at TCS.
|
I did helium pressure test on TM2 containment box window and HS line at TCS. @ 70psi helium for 3 minutes, HS:2.2XE-7 atm.cc/sec., Window:1.2XE-7 atm.cc/sec. There is no change on HS. But LR on window is bigger than before that was in E -9atm.cc/sec range. |

Tuesday, October 10, 2017, 10:38, David Wang, ITW, Standard Operation, , , 5 shielding blocks have been transferred from ITE to ITW .
|
ITW is configured to take proton beam. |
|
Tuesday, October 10, 2017, 10:45, David Wang, Conditioning Station, Repair, , , Re-route TCS water lines. 8x
|
TCS cooling polyurethane lines have been re-routed to solve to HV sparking issue on old configuration between lines and bais plate. New re-routed system is tested to 70KV without spark. No leak has been found on new lines after the test.
ECO 4369, drawings and models IRH1715, IRH1716 have been issued and released for this job. Drawings and Models are located in PDM-ISAC1 -TCS polyurethane water lines re-route folder. |

|
Chad and I leak checked TM4 HS line after new target is installed yesterday. No leak has been found. Also, I helium pressurized the HS line at TCS this morning. TM4 HS line is good on this test. The TM4 gas line configuration on TM4 top is leak check as well. No problem. |
|
Thursday, November 09, 2017, 09:34, David Wang, Conditioning Station, Standard Operation, TM2, Ta#55, Leak check on TM2 HS line at SHC and TCS.
|
The TM2 HS line was leak checked at SHC yesterday . 0.9xE-9 atm.cc/sec.Helium sprayed by Chad, NO leak. It was helium pressurized at TCS this morning. Leak rat:2.5 XE-7 atm.c/sec. The result is same as last time check. No concern. |
