Friday, July 30, 2021, 16:19, Carla Babcock, ITE, Repair, TM4, Ta#62, Electrical issues on Ta62
|
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.
|
Friday, July 30, 2021, 16:31, Carla Babcock, ITE, Repair, , , ITE re-wire 
|
See the attached for the way ITE has been re-wired for the Ta62 run. Note also that the copper block in the schematic on TBHT negative may not actually
be connected. Wiring verification on Aug. 4. |

|
| electric check done in ITE. |
|
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. |
|
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, February 10, 2022, 12:42, David Wang, ITE, Standard Operation, , , ITE HV test woithout mdoule was done.
|
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". |
