529602025-06-05 11:20:54.846rhenriques-55.426Straight repeat | OK
529592025-06-05 10:51:58.333rhenriques-5.15.626Straight repeat | Similar to previous but 1st cycle is not longer
529582025-06-05 10:31:49.608rhenriques-5.2626Repeat 52949 and try to optimize plasma position and transitions | Higher Ip than in reference, prefill pressure lower though, 1st semi-cycle ends early not sure why
529572025-06-05 10:16:11.316rhenriques33.518Repeat with small tweak at the end of pos. semi-cycle | Did not make much difference
529562025-06-05 10:10:11.449rhenriques33.718Repeat with further changes | Positioning slighlyt better, lost 1st transition
529552025-06-05 10:00:55.993rhenriques33.318Repeat with adjustments of Bv for positive cycle only | Position seems to be worse than in previous pulse, 1st transition is back
529542025-06-05 09:53:19.553rhenriques33.618Repeat with adjustments on plasma position only, for both pos. and neg. cycles | Better positioning for positive cycles, but worse for first inversion
529532025-06-05 09:47:03.709rhenriques33.318Repeat trying to improve transitions and plasma position | Beter plasma positioning, transitions mostly the same
529522025-06-05 09:37:07.63rhenriques33.418Repeat aiming to have 3 kA in positive semi-cycle as well | Ip flatop value is as intended, transitions and plasma position need to be optimized
529512025-06-05 09:26:54.736rhenriques-33.818Repeat with current limited to 2.6 kA approx., 10 semi-cycles | -3 kA of neg cycles and 2.7 kA for positive ones, many pos. cycles failed, transitions not optimized
529502025-06-05 09:18:32.47rhenriques-4.5518Repeat 52944, plasma pulse with shorter semi-cycle duration for machine conditioning, 14 semi-cycles | Better than reference (Ip is higher)
529492025-06-05 09:11:01.468rhenriques-4.9526Repeat (3) 52941 to assess max Ip and wall conditioning | TF issue resolved (requesting different value to the DAC made it come back to life), slightly better than in reference
529482025-06-05 08:47:02.89rhenriques54.726Repeat (2) 52941 to assess max Ip and wall conditioning | Mostly the same but slightly higher Ip, TF current is at its minimum (DAC may not be working)
529472025-06-05 08:41:45.67rhenriques4.74.226Repeat (1) 52941 to assess max Ip and wall conditioning | Breakdown did not happen, only one positive semi-cycel (the 2nd one), Ip above 4 kA for more than 6 ms
529462025-06-05 08:34:59.364rhenriques000Repeat (1) 52941 to assess max Ip and wall conditioning | Forgot to trun on TF PS, no plasma
529452025-06-05 08:27:06.522rhenriques000Dryrun (file: dryrun_standard_2025_04_04_52149.cfg) no TF | PF currents OK
