|
It was noted on Nov. 9 that a squeaking noise was present when the turntable was rotated CCW with a module present.
Upon inspection, it appears the issue could be due to drive chain misalignment and improper tension. Furthermore, it was noted that a shaft collar |

|
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.

|
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 |

|
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. |

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 |

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. |

Carla did the test. and reported the result as following: HV testing of ITW is complete. It was pretty well behaved up to 59.5kV, and sat at
59kV for 30mins with no sparks (that EPICS caught). There was some strange behaviour of the current between 51kV and 53kV - it was jumping by 20uA or
more - but there didn't seem to be any voltage response, and it went away after 53kV (though it returned on the way back down). The test was done in Feb |

|
Carla did the test. That is what she wrote in Feb 04th: "I am done with the HV testing at ITE - the
results were the same as at ITW. It stayed at 59kV for 30 mins with no issues. Trying to go above 59.5kV is probably possible but a bit more risky. ITE
also has a band, from 54-56kV, where the current jumps around like crazy". |
