TCS:IG1S is reporting vacuum levels that seem to be too low (1E-10 to 1E-8 Torr). The gauge was connected to the controller for IG1, which showed the same value. A degas was performed for ~5 min.

This morning new water block fasteners and gas line capture nut fasteners were inserted into the hot cell. Window waterline blank off was removed from TM2, surfaces inspected and given a polish with Veltex (30 seconds, 70 psi) as there was a small bit of c seal residue. Transfer try with new source tray has been latched to the module.

Repair of the tray transfer fixture is complete (minus testing).

A distorted ball nut lock plate was replaced and thread loc added. to the ball nut/plate assembly. Testing will take place tomorrow once the thread lock has a chance to cure.

A parasite target has been transferred from SHC to NHC. It is a job to reduce SHC field for coming SHC entry job. The transfer is successful.

Bevan and I transferred five shielding blocks from ITW to ITE. ITE is ready for taking proton beam.

Transfer fixture has been remotely disassembled to the point where the ball nut lock plate assembly can be inserted into the tool port and the plate replaced by hand in the tool port without having to enter the hot cell. Straight head screws will be replaced with SHCS to facilitate easier re-assembly and future disassembly.

Entry  Monday, January 22, 2024, 10:16, David Wang, ITE, Standard Operation, TM4, UCx#, Tm4 waterlines helium pressure test and TM service cap helium leak check. 

Tm4 waterlines helium pressure test and TM service cap helium leak check was done last Friday. All water lines were pressurized with 70psi helium for 3 minutes each. The 3 minutes stable leak rate on all lines are less than 4.0 X E-9atm.cc/sec. some of lines had surging leak rate to 2xE-8 atm.cc/sec at the first 10 seconds of pressurization which should be a gas hammer result at the beginning. Based on the numbers, I would say all water lines are leak free still.  I did helium spray on TM4 service cap. There could be a small leak in high E-9 atm. cc/sec on ion gauge and steer service panel o-ring.  I will replace this o-ring when module is moved out of ITE. Other seals are leak free or less than 2.5X E-9 atm.cc/sec leak rate which are good. I am pretty confirm there is a small leak on ITE entrance module top. The leak rate and location will be confirmed when the rest of leak checks in ITE pit are done.

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.
