The spent Ta#65 target was removed from the south hot cell and placed in the spent target vault. It was placed in pail #284 and placed in spot 2B. It
was 41 mSv/hr at 1 m upon removal. Target index spreadsheet updated. |

Thursday, June 23, 2022, 13:04, David Wang, Conditioning Station, Standard Operation, TM4, Ta#64, helium pressure test on TM4 HS line.
|
With Ta#64 installed , TM4 HS line was helium pressure tested at TCS. base leak rate is 0.0XE-9 atm.cc/sec. HS line tested leak rate is 3x E-7 atm.cc/sec
on 5 minutes 50 psi helium testing. Leak check result wasgood at NHC by helium spray method. We decided to apply water to HS and all other water lines
still. The vacuum status is closely being watched. So far, TCS pumping down trend is still good. HS line supply water valve was switched on and off couple |

|
Helium pressure test on TM4 HS line at TCS is done. LD base leak rate 0.0 xE-9 atm.cc/sec. Helium pressure 70psi. HS line had been helium pressurized
for 5 minutes during the test. No response on LD. HS line with Ta#63 is leak free. |

Thursday, July 08, 2021, 11:45, David Wang, South Hot-Cell, Standard Operation, TM4, Ta#62, TM4 Ta#62 leak check and lectrical check result at SHC and TCS.
|
At SHC: HS line no leak . electrical check result is fine. At TCS: helium pressurized HS line to 70psi, 3 minutes. LD leak rate 0.0xE-9atm.cc/sec
, no response. |

|
TLDR: TBHT voltage too high and rising too quickly with TGHT current - voltage
limited. TGHT power supply tripped breakers somehow. ITE:EL not outputting voltage.

Wednesday, August 26, 2020, 09:52, David Wang, South Hot-Cell, Standard Operation, TM2, Ta#60, Ta#60 target electrical check and leak check at SHC.
|
Electrical check and leak check at SHC. NO leak. electrical check ok. Before target on, A is short to PQ, RU is short to HS ( 60KV bias)
as we measured before. |
