523342025-04-15 15:36:00.543rhenriques1.65.2417Straight repeat | Mostly the same as in previous
523332025-04-15 15:27:31.494rhenriques1.64.717Repeat increasing Ip a little bit | 10 semi-cylces have failed and positive cycles need clear adjustment to improve current flattop
523322025-04-15 15:18:19.75rhenriques1.34.517Repeat | Most positive cycles have failed
523312025-04-15 15:13:21.667rhenriques1.34.2517Repeat | All cycles good
523302025-04-15 15:09:15.47rhenriques1.33.9517Repeat 52325 (back to higer current) | almost all positive have failed
523292025-04-15 15:00:49.128rhenriques0.752.517Repeat with lower prefill pressure | Not better
523282025-04-15 14:52:09.327rhenriques0.752.4517Repeat reducing Ip even further | Ip value looks OK, many cycles failed most of them negative ones
523272025-04-15 14:38:19.052rhenriques0.9317Repeat reducing Ip | 9 semi-cycles failed
523262025-04-15 14:24:10.064rhenriques1.13.4517Repeat 52063 with controlled Ip (via reduced Iprim) | Plasma current is higher than in reference, 9 semi-cycles failed (all negatives)
523252025-04-15 13:55:01.76rhenriques1.34.517Repeat | 1 semi-cycle failed, HXR still observed mainly at the start of the positive semi-cycles
523242025-04-15 13:48:25.016rhenriques1.34.217Repeat with a bit more prefill pressure | 17 (positive semi-cycles) failed
523232025-04-15 13:42:06.011rhenriques1.34.517Repeat with higher prefill pressure to prevent runaway electrons (it turns out HXR dignostic is still working) | 1 failed semi-cycle, still some HXR observed, but lower amplitude
523222025-04-15 13:36:38.38rhenriques1.34.3517Repeat | 3 semi-cycles failed
523212025-04-15 13:26:13.485rhenriques1.34.317Repeat | 1 failed cycle
523202025-04-15 13:21:52.241rhenriques1.34.317Repeat | 7 failed semi-cycles
523192025-04-15 13:16:35.109rhenriques1.34.317Repeat | 3 semi-cycles failed
523182025-04-15 13:04:29.656rhenriques1.34.417Repeat | 5 failed cycles
523172025-04-15 13:00:15.74rhenriques1.34.317Repeat | 2 failed semi-cycles
523162025-04-15 12:56:08.56rhenriques1.34.317Repeat with lower prefill than previous | All cycles, good. Prefill was about 7.6e-5 mBar at MC
523152025-04-15 12:51:42.156rhenriques1.33.817Repeat | 7 failed semi-cycles
523142025-04-15 12:47:33.84rhenriques1.34.3517Repeat, with a bit lower prefill pressure | 7 failed semi-cycles
523132025-04-15 12:43:26.66rhenriques1.3417Repeat | 4 semi-cycles failed
523122025-04-15 12:39:17.031rhenriques1.33.917Repeat | 6 semi-cycles failed
523112025-04-15 12:34:47.444rhenriques1.33.917Repeat | 4 semi-cycles failed
523102025-04-15 12:29:12.689rhenriques1.3417Repeat | Good, all cycles successfull
523092025-04-15 12:23:44.614rhenriques000Repeat 52307 to assess conditioning | Plasma real-time controller did not run, no plasma
523082025-04-15 12:11:32.875rhenriques000Dryrun (file: dryrun_standard_2025_04_04_52149.cfg), no TF | Breaker for Primary coil was open, so no Iprim, Iv and Ih OK
