Monday, July 26, 2021, 17:23: Roughing
Monday, July 26, 2021, 17:55: Turbos on.
Monday, July 26, 2021, 18:03 : TP1A timed out ...again
Monday, July 26, 2021, 18:03: Bypassing BV1A. TP1A reset and on. turbos at speed.
Monday, July 26, 2021, 18:05: IG1 on.
Monday, July 26, 2021, 18:26: IG1 @ 1.97e-5 T.
Monday, July 26, 2021, 22:33: IG1 @ 2.41e-6 T
Monday, July 26, 2021, 22:33: IV4 open.
Monday, July 26, 2021, 22:55: BIAS/EZL/EE to 10/6/1 kV. No problem. All set to 0.000 kV again
Monday, July 26, 2021, 22:57: Coil to 10 A. Anode to 100 V.. No problem. All set to 0 again.
Monday, July 26, 2021, 22:59: Auto-ramping TGHT/TBHT to 580/280 A @ 2A/min.
Tuesday, July 27, 2021, 06:32: IG1 @ 1.52e-6 T.
At 01:30, approximately 10 minutes after TBHT heater reached the desired current, the anode went from 0 to 1.5 V.
Tried to put anode voltage to 100 V but it got current limited as of 2 V.
Given that before heating the anode voltage was fine, I think the gas tube move again and made contact with the heatshield.
I will need to open this again :(
Tuesday, July 27, 2021, 06:41: Auto-cooling TGHT/TBHT to 0 A @ -4A/min
Tuesday, July 27, 2021, 09:08: Heaters @ 0 A. Anode still gets current limited.
Tuesday, July 27, 2021, 09:09: IV4 close. Timed out.
Tuesday, July 27, 2021, 09:09: IG1 off.
Tuesday, July 27, 2021, 09:09: Turbos off.
Tuesday, July 27, 2021, 11:13: Venting.
Tuesday, July 27, 2021, 11:58: Gas tube move and end up touching the heatshield again. When try to adjust it to add an insulator as an spacer, the gas line de-coupled from the target.
removing the target for re-installation and clearance addition.
Replace Ta capillary going into the target with the one from previous febiad as it felt sturdy and had better shape for clearance with the HS.
