524122025-04-21 17:57:58.374rhenriques1.43.326Repeat with further Bv adjustments | Much better, but can still improvel a little bit
524112025-04-21 17:53:33.489rhenriques1.4326Repeat with further Bv adjustments | Better but still quite late
524102025-04-21 17:48:48.358rhenriques1.43.1526Repeat with further adjustments to Bv waveform | BD still happening late, premag back to normal
524092025-04-21 17:42:06.876rhenriques1.43.426Repeat with Bv waveform mods to prevent forming plasma before primary inversion for breakdown | breakdown started much later than previous
524082025-04-21 17:31:52.902rhenriques1.43.326Repeat to see if premag comes back to usual values | Breakdown with an inversion as negative plasma current is observed before primary is inverted
524072025-04-21 17:27:38.153rhenriques1.43.426Repeat with lower prefill than in 52405 | breakdown happens much later but premag is again significantly different
524062025-04-21 17:18:41.137rhenriques1.43.326Repeat with higher prefill pressure | breakdown happens slightly later
524052025-04-21 17:11:01.592rhenriques1.43.626Repeat with same Bh as in 52403 and adjusting Bv (-100 A constant) | Good!
524042025-04-21 17:02:31.976rhenriques1.43.326Repeat with further changes | Moslty the same, slightly earlier and density ramp-up looks worse
524032025-04-21 16:53:08.337rhenriques1.43.426Repeat with further changes | Breakdown happens much earlier, but premag is now back to same as in previous earlier reference pulses
524022025-04-21 16:46:27.118rhenriques1.43.5526Repeat expecting pregam to be similar to all previous ones used as references | better althouth premag is still the same as in previous
524012025-04-21 16:38:07.27rhenriques1.43.526Repeat | Many cycles failed, breakdown happens later, but premag was significantly different
524002025-04-21 16:28:44.95rhenriques000Repeat with further adjustments (-41 A) | Controller failed, no plasma
523992025-04-21 16:22:39.492rhenriques1.43.126Repeat tyring to set expected optimum value constant from 0 s | better, breakdown happens earlier
523982025-04-21 16:14:59.603rhenriques1.43.626repeat with changes in opposite direction with Bh corresponding to -5 A | Worse than previous
523972025-04-21 16:10:20.583rhenriques1.43.526Reverting Bv to -200 A and changing Bh from -15 to -25 A | better than previous but still later than 52394
523962025-04-21 16:04:10.469rhenriques1.43.526Repeat with changes in opposite direction Bv with -150 A | Breakdown happens later
523952025-04-21 15:59:28.944rhenriques1.43.5126Starting to adjust breakdown by changing Bv to -250 A | Same as in previous pulse, one cycle failed
523942025-04-21 15:48:00.068rhenriques1.43.426Repeat adjusting Bv for Ip>0 for plasma position | many cycles failed
523932025-04-21 15:38:49.701rhenriques1.43.526Repeat with changes of Bh in transition to Ip>0 back to as in 52389 | Many failed cycles
523922025-04-21 15:29:31.965rhenriques1.43.626Repeat with further adjustments on Bh for transition to Ip>0 and on Bv for Ip>0 | Many cycles failed, prefill pressure was a bit higher
523912025-04-21 15:16:25.564rhenriques1.43.4526Repeat with further changes going back to previous better result | All cycles but transitions are still not good
523902025-04-21 15:08:42.097rhenriques1.43.326Repeat with further adjustments on Bh for transition to Ip>0 | Made it worse
523892025-04-21 14:59:13.265rhenriques1.43.426Repeat trying to improve transition to Ip>0 by adjusting Bh | All cycles, transition is much better, but still be improved
523882025-04-21 14:50:27.578rhenriques1.43.726Repeat with further adjustments on Bv for inverstion to Ip>0 and during Ip>0 for position | All cycles, but transitions are still not good
523872025-04-21 14:42:11.202rhenriques1.43.526Repeat adjusting Bv for inversion to Ip>0 | 2 cycles failed, transition to Ip>0 seems to be better
523862025-04-21 14:31:33.059rhenriques1.43.726Repeat trying to correct position on Ip>0 | only 1 cycle failed
523852025-04-21 14:24:09.242rhenriques1.43.4526Repeat with adjustments on inversion to Ip<0 | Slightly better, but still 2 semi-cycles failed
523842025-04-21 14:07:03.37rhenriques1.43.426Repeat with adjustments on Bh of Ip<0 to center the plasma | 5 negative cycles failed
523832025-04-21 14:00:13.776rhenriques1.43.426Repeat with changes in the opposite direction | Better
523822025-04-21 13:52:34.935rhenriques1.43.4526Repeat with adjustments on Bv for inversion to Ip>0 | 3 neg. semi-cycles failed, changes do not seem to have improved
523812025-04-21 13:37:00.726rhenriques1.43.326Repeat with adjustments on Bh for Ip>0 | Still failed pulses
523802025-04-21 13:23:39.222rhenriques1.43.526Straight repeat | 3 negative semi-cycles failed
523792025-04-21 13:17:28.736rhenriques1.43.626Repeat 52368 | OK
523782025-04-21 13:08:31.657rhenriques000Repeat with capacitor bank for primary coil back to nominal voltage ~260 V (was ~55 V) | OK, ADC_v_primary at about 255 V
523772025-04-21 12:58:09.205rhenriques000Repeat with dryrun configuration loaded | OK
523762025-04-21 12:45:07.233rhenriques000Dryrun (file: dryrun_standard_2025_04_04_52149.cfg) no TF | Forgot to load MARTe config (repeated previous pulse)
