Tom Gauss inspected  two target module lifting frames ITA0494-1997-01 and ITA0494-1997-02 yesterday. He certified the use of these two frames for 2025. Inspection tags have been issued and attached to frames. He has inspection record on them. 

Tom Kauss inspected target hall crane below hook attachment pins and plates ITA6550-01 yesterday. He certified the use of these pins and plates for year 2025. The inspection of these pins and plates was in Target hall crane annual check list. It was issued as a calibration index by Isaac Earle in 2022-Feb-08.  After inspection, The inspection tag  was issued. Tom has an inspection record on this job.

ITW/ITW 24VDC electrical connectors for TP BVs MRO has been done. 

HALCW pump ITC:MP1 has been started. water are supplied to both ITE and ITW system. all water signals for individual circuits work fine. no major leak on system. Some small water seeping from small ball valve stems are found in ITW. they will be fixed soon.

Remotely removed TM2 from S-W silo to SHC . Peter and I did the move. It is successful.

Plant Group Gabril.T organized a target pit CAD filter replacement and testing yesterday. My group helped on this job.  small 3T hoist was used for the job.Still the filter needs to be pushed manually on crane to south into position because of crane access limit on south.  The replacement job went well. Later, Gabril reported his test result is good as well.

TM2 has been moved from SHC to TCS successfully. Travis and I did the move.

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.

TM4 electrical check at SMP(vented) without target: PQ is dead short to RU. PQRU to 60kv bias,750Kohm at250V. other things are good. Notes: In attachment files all hand writing and circled TM2 should be TM4.  the results are measured on TM4 not TM2.

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

HALCW pump ITC:MP1 and MP2 phase current draw measurement result: water supplied to both station. MP1: Black 17.0A, blue 16.9A, red 16.7A.   MP2: black 17.3A, blue17.8A, red 17.3A.    The results are good.  No concern on both motors.

 ITW/ITE water system manual valves water small leak inspection and repairing job is done. Small water drippings have been found on ITE: manual supply and return(valve stems).  ITW: 2A window supply(valve stem), collimator supply(valve stem),EE return(valve stem), HS supply and return(valve stems), tube heater supply and return(valve stems). all small leaks are repaired. 

After waste transfer, I did a SHC field measurement from TH through top flange opening. The general field around manipulator maintenance working area is 550 to 650 usv/hr(0.4 to 0.5 meters above table). some area on work table where target fragile material stayed before have 1.0 to 1.3 m/sv (closing to contact measurement). The spreading of target material dusts deposited on table, and affected the whole cell field in my view. 

HALCW resin can loop two filters have been replaced. no water leak on after job check.

Chole and I finished ITW water signals interlock. No issue.

Service of  Parker 1/4 quick connectors in ITW and ITE have been done.  all 28 female connectors were serviced. o- rings and valve stem in quick connectors were replaced. the serviced connectors have been installed back to ITW and ITE.  Visually inspected all connectors with flowing through them. No leak, and they function well. 

To prevent TP bearings seize during shut down, ITW:TP3,TP4, TP1S TP4S have been started since March 06th. They work fine.  The plan is to switch them off this Thursday, and restart them in May before ITW in use.

ITE water signals interlock annual check is done today. all interlocks work . No issue.
