522732025-04-11 16:27:09.424rhenriques-1.9034.617Repeat with further adjustments | Better, but still need ajustments
522722025-04-11 16:11:43.449rhenriques-1.864.417Repeat with further adjustments | Slightly better, got last negative semi-cycle
522712025-04-11 15:57:55.325rhenriques-1.84.3917Repeat with further adjustments | One less than previous and remaing ones failed
522702025-04-11 15:46:10.485rhenriques-1.7454.4217Repeat with further adjustments | One more successful, but there other ones are still failing
522692025-04-11 15:38:08.656rhenriques-1.7674.2217Repeat with further adjustments | One more successful, but there other ones are still failing
522682025-04-11 15:25:57.649rhenriques-1.776417Repeat with further changes and reduced number of semi-cycles to 20 (was 50) | Still failing
522672025-04-11 15:16:00.378rhenriques-1.7414.0717Repeat tweaking fields to get negative cycles back, back to nominal prefill pressure ~1e-4 mBar at MainChamber | negative cycles still failing
522662025-04-11 15:05:27.971rhenriques-1.4674.517Repeat with much higher prefill to try to get the negative cycles back | Negative cycles still not there
522652025-04-11 14:53:15.27rhenriques-1.7417Repeat, maybe with a bit more prefill pressure | Ip spikes going about 1.5 kA, but neg. semi-cylces are failing
522642025-04-11 14:46:54.756rhenriques-1.4173.917Plasma pulse, repeat 52250 | Several semi-cycles failed
522632025-04-11 10:40:16.256rhenriques000Repeat the 280 A one (#52257) | OK
522622025-04-11 10:35:48.228rhenriques000Repeat with controlled current, requesting 25 A | OK
522612025-04-11 10:31:50.432rhenriques000Repeat with controlled current, requesting 50 A | OK
522602025-04-11 10:27:19.676rhenriques000Repeat with controlled current, requesting 100 A | OK
522592025-04-11 10:21:53.22rhenriques000Repeat with controlled current, requesting 150 A | OK
522582025-04-11 10:09:50.026rhenriques000Repeat with controlled current, requesting 200 A | OK
522572025-04-11 10:02:58.376rhenriques000Repeat with controlled current, requesting 280 A | OK
522562025-04-11 09:58:24.756rhenriques000Repeat with Vertical field only, maximum current, repeat 52235 | OK, current decays during pulse
522552025-04-11 09:51:18.595rhenriques000Repeat with controlled current, requesting 25 A | OK
522542025-04-11 09:47:17.092rhenriques000Repeat with controlled current, requesting 50 A | OK
522532025-04-11 09:41:02.672rhenriques000Repeat with controlled current, requesting 100 A | OK
522522025-04-11 09:29:13.681rhenriques000Repeat special dryrun #52233 after having swapped chopper module no.26 (coil no. 2) with no.16. Horizontal field only, maximum current | Signal of coil no.2 is much better now
