Monday, January 10, 2022, 09:31, David Wang, ITE, Standard Operation, TM4, , 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 |

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. |

|
An issue was observed in which the target hall crane was not functioning: the N-E-S-W and up/down motions did not work, however the rotation motion did
work. These symptoms were similar to what was observed in the past under https://elog.triumf.ca/TIS/RH-ISAC/2039
and https://elog.triumf.ca/TIS/RH-ISAC/1845 |

|
A rotary limit switch was installed, attached to the shaft adjacent to the drive motor for the vertical drive system. This limit switch is not yet wired
to the control system and operational - this will be done at a future date and the e-log will be updated.
