TCS was argon vented this morning between 6:00 and 7:30am for TM4 moving to ITW.

TM2 was moved from silo to TCS yesterday morning. The move is smooth.    TCS vacuum system was started after. TCS and TM2 pumping down is ok so far.

refilled TCS:TK2 to 27.4 inches to compensate water lost during THC filters change.

TCS water system  five filters were changed yesterday by plant group Dan.T. Service labels on filters are updated.  No water leak after job.

TM2 is moved from TCS to silo this morning. The move is smooth.

  couple of E-8 to low E-7 atm.cc/sec leak were found on TM2 service cap top air to vacuum  o rings.  Replaced these leak o ring seals including o ring on IG1 and steerer service panel,o rings on MSP, EE, D blue nylon and copper feed through, and o ring on a round blank off beside MSP terminal on second row. 

2024-july-03 update: TM2 was leak checked again at TCS. no air to vacuum leak on module top. i helium pressure tested(60psi) all water cooling lines (except HS) . They are leak free.

Tm2 has been successfully moved from SW silo to TCS.

Tm2 has been moved from TCS to SW silo. the move is smooth.

TM4 has been moved from SHC to TCS. The move is successfully.

TM4 has been moved from SHC to TCS. The move is successful.

TM4 has been moved from SHC to TCS. The move is smooth.

TCS water system resistivity analyzer has been repaired. Two diodes and one capacitor on PS board were broken. They were replaced. Installed analyzer back and tested it in system. it works fine. Operator closed e-fault, removed force on TS5, and enabled alarm on TS5 and TC1.

TCS water system has been started for functional test. System parameters including  pressure, all temperature sensors, flow rate sensors, resistivity are ok. I will watch on chiller CP1/2/3 in rest of the week and make sure chiller CP1/2/ 3 auto stage in/out work fine.

TM3 was moved from SHC to TCS with UCx#47. The move was smooth.

A complete TM3 electrical check at TCS under good vacuum has been done. Pin 14 to 60KV only has 8K ohm on ohmmeter check , and it's about 2Kohm @250V Megga. It's low in resistivity. The pin 14 is for thermocouples only so no big concern.  The rest things are good. See attachments.

Tm3 has been moved  from TCS to silo. The move is successful.

TM2 TP1/TP2 and TCS:TP1S have been started at TCS. The starting time and operation of turbo pumps are ok. TM2 had been stored in silo since last Oct.

TP1/TP2 work fine over long weekend and TCS vacuum is good. I switched off TCS vacuum system.

TM2 has been moved to TCS and under good vacuum. TP1/2 work fine.  Electrical check: A to PQ still dead short. B to C @250V 3.8M which is ok still . We knew these two things before. Other things are good. Vacuum: air to vacuum seals on TM2 service cap are good. Helium pressure test on all water lines are good. HS line no target so can't be tested. But We did helium pressure test on each target change so it's fine.

TM2 has been moved from TCS to west-south silo. Travis and I did the job. The move is successful.

TCS water system filters annual replacement has been done. Plant group Dan Tower finished the job and updated the inspection tags .
