  1553   Thursday, June 08, 2017, 07:37 David WangConditioning StationStandard OperationTM2 Helium pressure test on TM2 water llines at TCS.
  The helium pressure test on HS line is done at TCS this morning. I got the same result as last time when we helium pressure it it with first target in April. The leak  rate on this line is 1.8 XE-7atm.cc/sec. So, we know this leak is mostly on the line, but not on the VCR joints connecting the target.  See attachment for last time(April) checking e-log. The leak could be from water block which is same as other lines. I do not think this leak rate will affect the operation.

The attachment can not be opened for some reasons. Please check TM2 leak check  2017-03-13 e- log for last time test result and comment.

  1554   Thursday, June 08, 2017, 08:35 David WangConditioning StationDevelopmentTM2 TM2 gas line reconfiguration on the module top.

Reconfigured TM2 gas line on the module top. It matches with the febiad gas line we are using on service tray now. Facing the module, both of them should be that right side line of two SST lines on feed-through. The gas line on TM2 was leak checked with a blind cap installed on service tray side and LD connected on module top this Tuesday. It is leak free with helium spray on the top of module and service tray.

Yasmine and I connected TM2 in ITW today. the control page is set to febiad mode. Both gas line in ITW are opened for febiad run. All connections are double checked. Module connection checklist is finished.  All turbo pumps are started now. Everything is good so far. The TM2 is ready for conditioning when the ITW vacuum is good enough.

Tm2 was disconnected in ITW yesterday. ITW EL cable crimp ring was broken. John Chow replaced this ring this afternoon.

  1591   Wednesday, August 02, 2017, 15:13 David WangSouth Hot-CellStandard OperationTM2 SHC, TM2 leak check on HS line.

HS line is leak checked at SHC this afternoon by helium spay.  Leak detector base LR 0.0 XE-9atm.cc/sec. Base pressure 0.0Xe-4 torr. No leak has been found. This line will be helium pressured  at TCS. It had  a 1.7XE-7 atm.cc/sec leak rate on 70 psi helium at TCS  during last two target  checks.

 2017-08-03. Helium pressure test on TM2 HS line at TCS is done. 70psi helium, 3 minutes. base leak rate 0.0xE-7 atm.cc/sec. Result: 1.8XE-7atm.cc/sec leak which is almost same as before. This line has a very small leak on water block seal under helium pressure test  which we knew already.

  1622   Thursday, September 21, 2017, 16:26 Anders MjosSouth Hot-CellStandard OperationTM2 Inspection of Source Tray

Chad and Anders inspected the Source Tray today using the camera in the hot cell. A dark spot was observed on one of the four insulators separating the Extraction Electrode from the Ground Electrode. This could potentially influence the high leakage current. Some discolored areas were also observed in the Service Tray, but these was present when the module was built. See attachment for details.

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.
