Entry  Thursday, October 19, 2017, 10:11, David Wang, Conditioning Station, Standard Operation, TM4, , Leak check on TM4 HS line at SHC and TCS. 

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.

Entry  Monday, January 29, 2018, 06:51, David Wang, Conditioning Station, Maintenance, TM1, , TCS and TM1 vacuum pumps switched off 

TCS and Tm1 vacuum pumps are switched off this morning. TM1 TP1and TP2 work fine during this test period. Tm1 will be moved back to silo this morning.

TM1 IG1 stopped work during the test period. It could be broken. We will only replace this gauge if TM1 is used in ITW again.

Entry  Tuesday, May 15, 2018, 07:44, Travis Cave, Conditioning Station, Standard Operation, TM4, no target, Module move 

 TM#4 was moved to the conditioning station from the south hot cell. The module was moved with out the containment box.

Entry  Tuesday, May 15, 2018, 10:21, David Wang, Conditioning Station, Standard Operation, TM4, , Tm4 water circles helium pressur test result  

  Helium pressure test on TM4  water lines is done this morning. 70 psi helim , 1 minutes time to each circle. The result:

A(oven+): 0.00xE-9 atm.cc/sec

B(Oven -): 8.1Xe-7 atm.cc/sec

C(tube -): 0.00xE-9 atm.cc/sec

D(tube+): 1.0xE-5 atm.cc/sec

PQ(coil 2): capped on top. water lines were removed because of leak

RU(Coil1): 0.00xE-9 atm.cc/sec

EE: 0.00xE-9 atm.cc/sec

MSP: 0.00xE-9 atm.cc/sec

HS: No target, capped on top. It was fine on last target check in 2017 Oct.

window: Capped on top. Containment box is not installed.

The leak check on D line caused the IG1 small response during test.

B and D circle are double checked. The reasults are same.

D line leak is in E-5 atm.cc/sec range. It is possible to locate it by using helium spray method in SHC. The containment box is not on so it should be easy to do it.

Switch on IGA gauge at TCS and apply helium and water at certain psi to check the IGA response may give us more information on these leaks.

 All lines were test in last year shut down. They were good.
