Monday, November 29, 2021, 12:16, David Wang, Spent Target Vault, Standard Operation, , , Five spent targets have been loaded into F308s
|
We loaded UCx #29 , SiC #38 , Ta#53, Ta#56 ,and Ta#57 from mini storage into F308 flasks. Later, the flasks are transferred from TH
to B2 HC service area. In TH, Working area and Mini storage are cleaned and surveyed. Tools are cleaned and surveyed as well. No contamination.
Mini- storage is empty now. |

Thursday, January 06, 2022, 10:37, David Wang, ITW, Standard Operation, TM2, , 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:
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 |
|
Thursday, January 06, 2022, 13:54, David Wang, ITE, Standard Operation, TM4, , 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. |
