Monday, January 22, 2024, 10:16, David Wang, ITE, Standard Operation, TM4, UCx#, Tm4 waterlines helium pressure test and TM service cap helium leak check.
|
Tm4 waterlines helium pressure test and TM service cap helium leak check was done last Friday. All water lines were pressurized with 70psi helium for
3 minutes each. The 3 minutes stable leak rate on all lines are less than 4.0 X E-9atm.cc/sec. some of lines had surging leak rate to 2xE-8 atm.cc/sec
at the first 10 seconds of pressurization which should be a gas hammer result at the beginning. Based on the numbers, I would say all water lines are leak |

|
ITW entrance module has been moved from SHC to ITW. A slightly bump on module shielding block bottom side corner to tank vessel side when lowed module
into tank. No big concern on this slight bumping. Otherwise the move is perfect.

|
On Jan. 9 we did the PIE on Ta#66. Opened the heat shield and removed the EE. The inside of the heat shield was very black with lots of flakes falling
off. The target itself looked overheated, and the container looked pretty bad for a Ta target. The outside of the EE looked perfect but after removing
it there was a lot of black stuff on the side and we saw that the Re foil was curled up. Jens said during the runtime that he saw something that looked |

ITW entrance module has been moved from ITW to SHC. The move is smooth. I cleaned entrance module tank flange and o r-ing slot. entrance
module tank flange o ring is replaced . |

ITW entrance module has been disconnected per document190510. It will be moved to SHC for diagnostic group tomorrow. |
Thursday, January 11, 2024, 13:54, David Wang, Conditioning Station, Development, TM3, , TM3 servic cap air to vacumm seals leak check.
|
After Tm3 service tray and service cap installation, TM3 service cap air to vacuum seals leak check has been done at TCS. TCS:IG1 and IG1S are at low
E-7 torr range. leak detector base 0.0XE-9 atm.cc/sec, base pressure0.0X E-4 torr. I sprayed helium to all new air to vacuum seals
on service cap. No leak on seals. The leak check has been repeated 2 times with same result. |

|
To deliver stable beam to RadMol, started heating UCx#43 up again. Target was overheated during initial conditioning in Nov but then ran well for
4 weeks. During the run time, the TGHT voltage jumped around and this was reflected in the ion current, but yields seemed unaffected.
When re-heating it, the TGHT voltage was very unstable and once it got to 440A, it went into voltage limiting mode. We ramped down and it was still |

|
The spent Ta#66 was moved from the south hot cell to the spent target vault, it was placed in pail#285 and placed in spot 5B of the vault. The
target was 46.2mSv/hr when removed from the south hot cell. See the attached PDF for vault details. |

|
ITW primary and secondary vacuum vessel leak check and TM2 water lines helium pressure test are done today. No major concern. see attachment for small
air to vacuum leak we found. TM2 water lines helium pressure test is fine. HS and window line leak rate are 1.4Xe-8 atm.cc/sec. all other
water lines are below 3.0XE-9atm.cc/sec. |

Tuesday, January 02, 2024, 15:58 :
Started HV ramp up on TM3 service tray about 3pm today. Had to bypass TCS:BIAS interlocks to make it work - there are some flow restrictions on
the water lines that are causing the flow interlock to periodically trigger. The water flow it not very important for this test as long as the water is |

|
Thursday, December 21, 2023, 09:36. ITE multipin wires 12-13-14-15 were rewired from the RF driver box to a TC datalogger inside the HV cage. A
webcam was also installed to monitor the TC values during operation. This is only a temporary setup to be upgraded during shutdown. |
