Tom Kauss inspected target hall crane below hook attachment pins and plates ITA6550-01. He certified the use of these pins and plates. 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 and attached to pin. Tom has an inspection record on this job. See attachments.

  2286   Monday, January 10, 2022, 09:31 David WangITEStandard OperationTM4 ITE primary and secondary vacuum vessel leak check.

ITE primary and secondary  vacuum vessel leak check has been down.  Base leak rate 0.0x E-9 atm.cc/sec on LD. Only 2.8 XE-9 atm.cc/sec leak has been found on big T tank seal which is very tiny. all other seals are perfect leak free.   No concern

  2285   Thursday, January 06, 2022, 13:54 David WangITEStandard OperationTM4 helium pressure test on TM4 internal cooloing lsine at ITE.

Helium pressure 70 psi. 3 minutes on each circle untill LR on LD is balanced. Base leak rate on LD:0.0xE-9 atm.cc/sec.   The result:

A:   slowly to1.8Xe-8atm.cc/sec after 2 minutes and balanced there. 

B:   slowly to 2.0XE-8 atm.cc/sec after 2 minutes and balanced there.

C:  quickly response  to 3.1XE-8 atm.cc/sec and balance there.

D : slowly to 3.0X E-9 atm.cc/sec and balanced there.

All others including coil1, coil 2 ,MSP, EE, HS, window are perfectly leak tight. No response on LD.

 The leak rate on A,B,C,D are in low E-8 or E-9 atm.cc/sec range.  They should seal cooling water without leak.    No concern. 

 

  2284   Thursday, January 06, 2022, 10:37 David WangITWStandard OperationTM2 ITW vacuum vessel and TM2 internal cooling lines leak check in pit.

Frank and I finished ITW and TM2 leak check. TM2 internal water-cooling lines are leak free. They passed 70 psi helium pressure test. We found some small leaks on ITW primary and secondary vacuum vessel. I list them here:

  1. Exit module 2 service cap top plate to cap body O-ring at SW corner. Leak rate 2XE-8 atm.cc/sec. It is an old leak we found before. Solution: I sprayed high vacuum resin to leak area. It is improved to 3Xe-9atm/sec now. We can leave it there.
  1. Exit module 1 module to tank flange o-ring at target module side and north side. Leak rate 3XE-8atm.cc/sec. Solution: replace the o-ring. It involves in disconnect exit module 1 and remove it out. We may or may not change it. Let's check the schedule and discuss it later. We need Travis help on module moving out.
  2. Exit module 1 north side sqaure service panel o-ring. Leak rate 2XE-7 atm.cc/sec.  Solution: replace the o-ring. It is a straight forward job.  It will be done this shut down.
  3. Exit module 1 north side round roughing valve panel o-ring. Leak rate 8XE-9 atm.cc/sec. Solution: Replace the o-ring. It involves in disconnecting and removing ITW RV4.  It could be done this shut down.
  4. Big T tank o-ring seal underneath the flange at exit 1 module north side . Leak rate 3XE-8 atm.cc/sec. Solution: None. All modules and module base flange have to been moved out to replace this big o-ring.  It is a huge project to change this o-ring .  I checked this big o-ring seal every year. It is first time a small leak is found.  Maybe, we could try high vacuum resin spray first.
  5. Dump module flange o-ring at the side by Target module. Leak rate 8XE-9 atm.cc/sec. It cannot be confirmed since the TM o-ring is just beside it. Mostly, the leak is on dump module side. We changed TM flange o-ring every year. But we never changed dump module flange o-ring in history. Many copper cooling lines above the dump module has to be removed to remove the dump module out. I do not think we have time to do it this year. Also,  the leak rate is pretty small. Maybe, we can schedule it next year.

  Most these small leaks are close to turbopumps. This could be the reason the ITW vacuum on gauges are still pretty good.
