Tom Kauss inspected target hall crane below hook attachment pins and plates ITA6550-01 yesterday. 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

  2410   Wednesday, January 25, 2023, 06:52 David WangITEStandard OperationTM4UCx#41ITE primary and secondary vacuum vessel air to vacuum seals leak check.

ITE primary and secondary vacuum vessel air to vacuum seals leak check was done this week. One leak has been found on IG1S feed through to entrance module surface seal. It explains what we saw on ITE IG1S readings change(from low E-7 torr to 1Xe-6 torr) on December 22, 2022.  This leak seal will be replaced soon.

2023-Jan -27.  O-ring seal 229# was replaced on ITEIG1S feedthrough to entrance module surface sealing. Also o-ring seal 034# was replaced on the blank off cover beside the feed through to entrance module surface sealing. Since these o-rings are too close to each other. It is better to replace both of them to avoid misreading in leak check.

 UC#40 was moved from the north hot cell to the spent target vault. It was placed in pail #278 put in spot 1B and was 15.6 mSv/hr when removed from the north hot cell.

Also Ta#62 in pail #256 was moved from spot 7B back to 7A where it was originally located. This pail in the future will have to be repacked due to the fact it lacks a reinforcing disc in the bottom of the pail.

  2401   Friday, January 06, 2023, 10:38 David WangITWStandard OperationTM2 ITW/TM2 vacuum vessels leak check and TM2 internal cooling lines helium pressure test.

ITW and TM2 primary and secondary vacuum vessel leak check is done. Leak detector is connected to ITW TP1. Base leak rate on leak detector is 0.0 x E-9 atm.cc/sec.   See attachment for the result.  No big issue. Two old leaks we found last year at location D and E disappeared in this check. We did Vacseal resin spray on them last year.  It looks like the Vacseal spray works .  From the result , I can see the o-ring between exit 1 module and T - flange is closing to the end of the life.  There are two small leaks on this o-ring now at A and B location. We plan to change this o-ring next winter shut down. We do vacseal spray on them this year. The big O-ring between tank vessel and T -flange looks still ok. Two small leaks are found on location F and G on this O-ring. Not much we can do on them. The leak on location C and B were sprayed with resin yesterday after leak check. They are leak free after spray on check. I will double check them. Leak on location A will be resin sprayed after TM2 is removed and ITW is under vacuum.   All TM2 internal water-cooling lines are helium pressurized (70 psi) for 5 minutes each. HS shows 2.5 X E-9atm.cc/sec leak rate. The rest lines are 0.0 X E-9 atm.cc/sec.

The following three pails were moved from the main storage vault to the mini-storage vault:

1. #211, Ta#58 (formerly vault location 3C)
2. #217, ZrC#8 (formerly vault location 3A)
3. #228, UC#37 (formerly vault location 1B)

 

The target index spreadsheet has been updated.

[edit 2023-01-03] The crane was powered back on this morning - there do not appear to be any faults and it seems that the crane was unaffected by the power outage.

The ISAC target hall overhead crane was powered off for the holidays. Note that this may result in the commonly observed PLC battery failure issue when the crane is powered back on in the new year.

  2398   Friday, December 16, 2022, 16:35 Adam NewsomeSpent Target VaultStandard Operation  Pails measured, moved to mini-storage vault

The mini-storage vault is now full and ready for transfer to F-308 flasks.

The following measurements were made on other pails:

  • #211 (vault location 3C): 4.21 mSv @ 1 m
  • #217 (vault location 3A): 1.05 mSv/h @ 1 m
  • #246 (vault location 6C): 1.98 mSv/h @ 1m
  • #274 (vault location 1A): 4.78 mSv/h @ 1 m

  2397   Thursday, December 01, 2022, 13:45 Carla BabcockNorth Hot-CellStandard OperationTM4C#4Post irradiation inspection C#4

Post irradiation inspection of C#4 which was running in TM4/ITE was conducted at the NHC on Nov. 22 2022.

The yields from this target had been dropping and its behaviour was erratic, with the voltages on the tube and target jumping all over the place sometimes. The ion current on the FCs followed the voltages. We took this to mean the target container was breaking down.

Upon inspection we found the container looked pretty damaged - highly crystallized and distorted. The container had gone banana-shaped, but not in the usual direction. It had curved  in the direction of the ion source (see photos). The heat shield and other surrounding components were super clean, no deposits or marks at all.
