533272025-09-12 14:38:40.178rhenriques000Repeat (1) 53101 to assess max Ip and wall conditioning | No plasma, controller failed to trigger
533262025-09-12 14:25:06.708rhenriques-0.376.517Repeat | Slightly better
533252025-09-12 14:21:08.823rhenriques-0.37617Repeat | Mainly the same as previous
533242025-09-12 14:17:10.154rhenriques-0.396.517Repeat | Better
533232025-09-12 14:13:10.75rhenriques-0.37017Repeat with maximum inversion time increased to 5 ms (instead of 2.5 ms) | longer sustained plasma during inversion, better
533222025-09-12 14:08:37.978rhenriques-0.35017Repeat | Mostly the same again
533212025-09-12 14:04:22.621rhenriques-0.37017Repeat aiming for correct prefill pressure value (7e-6 mBar) | Similar to previous, prefill pressure still a bit low
533202025-09-12 13:59:26.729rhenriques0.371017Repeat | Better Ip peak but prefill pressue was a bit on the low side, still higher post plasma pressure
533192025-09-12 13:54:36.949rhenriques0.27017Repeat with correct prefill pressure | Lower Ip and overall performance than 53317, outgas pressure after pulse much lager than in #53317
533182025-09-12 13:50:23.162rhenriques0.2017Repeat after 1h10 of cleaning discharges | Wrong prefill pressure (too high)
533172025-09-12 09:59:31.482rhenriques-0.372.217Repeat | Marginally better
533162025-09-12 09:55:34.261rhenriques-0.38017Repeat | Moslty the same as previous
533152025-09-12 09:51:20.856rhenriques-0.372017Repeat | slightly better
533142025-09-12 09:47:20.14rhenriques-0.364.317Repeat | still improving
533132025-09-12 09:43:22.439rhenriques-0.33517Repeat | Improving
533122025-09-12 09:39:25.322rhenriques0.29217Repeat | Still improving but at very slow pace
533112025-09-12 09:35:27.006rhenriques0.25217Repeat | Negative semi-cycles are improving
533102025-09-12 09:31:30.369rhenriques0.25217Repeat | Some positive cycles starting to pickup as well, but not too different than previous pulse
533092025-09-12 09:27:33.244rhenriques0.28217Repeat | Mostly the same, although pressure after pulse seems to be lower
533082025-09-12 09:23:15.32rhenriques-0.244217Repeat with 30 semi-cycles (instead of 20) | Mostly the same
533072025-09-12 09:19:17.203rhenriques0.23017Repeat with 20 semi-cycles (instead of 10) | Mostly the same, the extra 10 are only negative cycles
533062025-09-12 09:14:58.759rhenriques0.23217Repeat | Mostly the same
533052025-09-12 09:09:15.195rhenriques0.245217Repeat with a slight increase on prefill pressure | smaller HXRs signal, Ip is lower due to the increased pressure, negative cycles seems to be picking up
533042025-09-12 09:04:10.359rhenriques0.36017Repeat | Plasma ended early, Ip is slightly better, but prefill pressure is going a bit to the low side
533032025-09-12 09:00:10.907rhenriques0.29017Repeat | Mostly the same, maybe a bit better for the negative cycles
533022025-09-12 08:53:50.459rhenriques0.29017Repeat | Marginally better
533012025-09-12 08:49:14.691rhenriques0.25017Repeat, with a bit less prefill pressure | More similar to 53298, pressure is slighlty lower
533002025-09-12 08:34:34.993rhenriques0.137017Repeat #53168 for wall conditioning (10 semi-cycles with controlled Ip at 1.3 kA), prefill set to 7e-6 mBar on Adm (pressure at MC not behaving correctly) | Same as 53298, but at bit less Ip
532992025-09-12 08:24:15.964rhenriques000Dryrun (file: dryrun_standard_2025_04_04_52149.cfg), no TF, tomography: same as in #53291 | PF currents OK
