526192025-05-05 18:06:39.895rhenriques4.27.226Repeat (1) 52604 to assess max Ip and wall conditionining | Higher peak current
526182025-05-05 18:00:31.581rhenriques1.42.726Repeat (2) | OK, with failed semi-cycles
526172025-05-05 17:56:29.081rhenriques1.42.826Repeat 52599 | Still cycles failing
526162025-05-05 17:42:07.734rhenriques1.42.715Repeat with increased time for inversion and lower Bv (-240 A) | Still no inversion
526152025-05-05 17:19:03.802rhenriques1.42.915Repeat, with further adjustments on Bv for transition to Ip<0 | still no 2nd semi-cycle
526142025-05-05 17:14:10.544rhenriques1.42.415Repeat trying to obtain 2nd semi-cycle | Not sucessful
526132025-05-05 17:00:38.89rhenriques1.42.815Repeat with some premag to bring the magnetisation down before breakdown (to prevent 1st cycle to saturate early) | Good, 1st cycle last the full length, check if it keeps like this from now on
526122025-05-05 16:41:14.779rhenriques1.43.115Repeat trying to improve transitions to Ip> 0 | 1st cycle got short because or iron saturation
526112025-05-05 16:33:31.441rhenriques1.42.115Repeat with further adjustments on Bv for Ip<0 | Still not there
526102025-05-05 16:26:20.832rhenriques1.42.615Repeat with adjustments on plasma position for negative cycle (changing Bv) | Seem to have improved slighlty but inversion to Ip>0 not sucessful this time
526092025-05-05 16:16:29.352rhenriques1.42.915Repeat with 14 cycles (instead of 8) and adjustment on Bv for transtion to Ip<0 | 3 sets of transtions from neg to pos but with failed cycles in between the sets, negative cycle position not centered
526082025-05-05 16:11:21.501rhenriques000Repeat with 14 cycles (instead of 8) and adjustment on Bv for transtion to Ip<0 | Forgot to open gas, no plasma
526072025-05-05 15:36:54.552rhenriques1.43.2615Straight repeat to check if 1st cycle runs full programmed length 15 ms | Mostly the same as previous, but primary saturates later (1s cycle has probably run the full length)
526062025-05-05 15:25:11.35rhenriques1.43.1515Repeat with adjustments on transitions waveforms | one successful transition between neg. to pos., still many cycles failed
526052025-05-05 14:56:49.286rhenriques1.4215Repeat (1) 52599 for wall conditioning, trying shorter cycles to check if transitions are more successful | only 4 cycles out of 8, mainly positivie ones failed
526042025-05-05 14:41:30.635rhenriques3.076.826Repeat (3) 52595 to assess max Ip and wall conditionining | More Ip than previous and reference throughout the pulse
526032025-05-05 14:36:58.183rhenriques36.9526Repeat (2) 52595 to assess max Ip and wall conditionining | Better, prefill pressure now closer to the one in reference
526022025-05-05 14:31:57.948rhenriques2.66.726Repeat (1) 52595 to assess max Ip and wall conditionining | Mostly the same as in reference
526012025-05-05 14:24:20.819rhenriques1.4326Repeat (5) 52592 for wall conditioning, with feedback on plasma position (with electric probes), PID soft control | Again, badly controlled
526002025-05-05 14:16:18.449rhenriques1.43.526Repeat (4.5) 52592 for wall conditioning, with feedback on plasma position (with electric probes), PID medium control | Plasma position not controlled properly
525992025-05-05 13:58:32.225rhenriques1.43.426Repeat (4) 52592 for wall conditioning, with adjustments on Bh to center positive cycle a bit better | improved for 1st cycle
525982025-05-05 13:37:47.532rhenriques1.42.926Repeat (3) 52592 for wall conditioning but without Ip variations | Still many cycles failing, may be due to lack of plasma position centering
525972025-05-05 13:25:23.303rhenriques1.42.726Repeat (2) 52592 for wall conditioning, with adjustments on fields to center positive cycle a bit better | posititive cycles keep failing and transitions are clrearly not optimized
525962025-05-05 13:13:57.905rhenriques1.42.526Repeat (1) 52592 for wall conditioning | OK, but cycles are failing a bit, postive cycle seems to loose centering position
525952025-05-05 13:05:19.145rhenriques2.86.626Repeat (3) 52585 to assess max Ip and wall conditionining | Slightly better than previous (prefill pressure was lower) and a bit better than reference
525942025-05-05 12:59:55.206rhenriques2.76.726Repeat (2) 52585 to assess max Ip and wall conditionining | lower max Ip, but slighlty longer and higher throughout

525912025-05-05 12:36:02.859rhenriques1.4326Repeat (4) | OK, but cycles are failing more
525902025-05-05 12:31:50.999rhenriques1.42.326Repeat (3) | OK, prefill pressure higher than previous pulses
525892025-05-05 10:58:33.332rhenriques1.43.226Repeat (2) | Prefill pressure may not be stable during pulse

525852025-05-05 10:32:12.684rhenriques2.66.526Repeat 52577 to assess max Ip and wall conditionining | Better, higher Ip overall and a bit longer
525842025-05-05 10:24:38.922rhenriques1.43.326Repeat | OK

525802025-05-05 10:08:17.321rhenriques1.43.4626Plasma pulse for wall conditioning, repeat 52571 | OK
525792025-05-05 10:00:31.992rhenriques1.85.926Repeat | Mostly the same behaviour as in the previous pulse

525772025-05-05 09:52:10.181rhenriques1.46526Repeat 52575 to assess max Ip and wall conditionining | current during flattop just abtou 1 kA, need a repeat as this one was first pulse of the day
