523072025-04-14 17:20:25.035rhenriques1.34.2617Straight repeat | More cycles failed
523062025-04-14 17:15:58.791rhenriques1.33.917Straight repeat | OK, some cycles failed towards the end
523052025-04-14 17:11:49.215rhenriques1.34.517Straight repeat | More cycles have failed
523042025-04-14 17:07:22.975rhenriques1.33.717Straight repeat | OK, still some cycles failures here and there but very few of them did
523032025-04-14 16:58:50.561rhenriques1.34.817Reverting Bh back to as in 52300 and increasing number of cycles to 50 | OK, very few cycles failed towards the end
523022025-04-14 16:52:30.292rhenriques1.3417Repeat with adjustments on the other direction | Worse than 52300
523012025-04-14 16:46:37.442rhenriques1.35.217Repeat with further adjustments on Bh for Ip<0 | Worse...
523002025-04-14 16:38:35.517rhenriques1.3517Repeat with further adjustments on Bh for Ip>0 | Better
522992025-04-14 16:31:37.067rhenriques1.34.717Repeat with further adjustments on Bh for Ip>0 | better
522982025-04-14 16:22:48.936rhenriques1.35.417Repeat with further adjustments on Bh for Ip>0 | Not sure if it did much, but may look slightly better
522972025-04-14 16:09:52.46rhenriques1.35.217Repeat with adjustments on Bh for Ip<0 | Start of Ip>0 cycles is better, but ending is worse
522962025-04-14 16:02:39.133rhenriques1.35.2517Repeat with adjustments on Bh for Ip>0 | Plasma is better centered but Ip>0 seems to be more resistive...
522952025-04-14 15:54:47.985rhenriques1.34.717Repeat with adjustments on vertical field for Ip>0 | Better position, now horizontal field needs to be adjusted
522942025-04-14 15:32:20.679rhenriques1.33.7517Back to previous development pulse, repeat 52290 | OK, all cycles
522932025-04-14 15:24:24.637rhenriques2.55.35Repeat | Same again
522922025-04-14 15:19:31.457rhenriques2.665.65Repeat | Mostly the same, with a bit higher current
522912025-04-14 15:13:03.35rhenriques2.455.35Plasma pulse based on AC40.cfg to check nominal configuration | Short lived pulse, needs to be adjusted
522902025-04-14 14:59:37.755rhenriques1.34.417Repeat with changes on vertical field of Ip>0 to improve positioning | better, but now horizontal field needs adjustment
522892025-04-14 14:48:42.093rhenriques1.34.217Repeat with controlled Ip at ~1.3 kA | Good, all semi-cycles are back
522882025-04-14 14:35:20.472rhenriques-2.32517Repeat 52273 without control of Ip | many positive semi-cycles failed
522872025-04-14 14:24:14.771rhenriques1.34.917Repeat reverting changes on horizontal field of Ip>0 | Still not good
522862025-04-14 14:07:43.497rhenriques1.34.617Repeat by reverting changes and adjusting horizontal field duing Ip<0 | Still not good
522852025-04-14 13:56:42.412rhenriques1.34.417Repeat with adjustments on vertical field during inversion to Ip<0 | Made it worse, more neg. cycles failed
522842025-04-14 13:36:37.886rhenriques1.34.417Repeat with adjustments on horizontal field for Ip>0 to better centre the plasma | less cycles failed, transition to negative cycles needs to be adjusted
522832025-04-14 13:17:15.12rhenriques1.34.217Repeat with back to larger Iprim adjustments to try to get flat Ip | Better
522822025-04-14 13:04:59.97rhenriques1.34.317Repeat with correction | Very small change, mods need to be larger
522812025-04-14 12:56:50.643rhenriques1.34.417Repeat trying to get a constant Ip flattop (start = end) | Too much correction
522802025-04-14 11:06:59.588rhenriques1.33.917Repeat with further adjustments, but this time for vertical position of negative cycle | less cycles failed but position is drastically different
522792025-04-14 10:54:10.705rhenriques1.3417Repeat with correction on the horizonta field to improve plasma positioning | Better but negative semi-cycles are still failing
522782025-04-14 10:12:59.288rhenriques1.33.617Repeat with further adjustments on Iprim waveforms | Still failed semi-cycles, vertical position too much off-center
522772025-04-14 10:00:09.062rhenriques13.417Repeat with higher Iprim request to see if it improves the equilibrium | Ip still looks a bit on the low side
522762025-04-14 09:39:56.59rhenriques13.417Repeat with correction on Primary waveform for inversions | Still some failed semi-cycles
522752025-04-14 09:30:40.214rhenriques13.517Repeat 52251 with Ip controlled (Iprim = 45 A) and fewer semi-cylces (20 instead of 50) | Some semi-cycles failed
