531422025-07-04 15:02:29.621rhenriques000Repeat (2) 53101 to assess max Ip and wall conditioning | Pulse failed, no plasma
531412025-07-04 14:58:26.976rhenriques-3.44.126Repeat (1) 53101 to assess max Ip and wall conditioning | OK, but still quite far from the reference
531402025-07-04 14:52:52.485rhenriques1.33.817Repeat | Plasma keeps evolving
531392025-07-04 14:47:16.585rhenriques1.33.817Repeat | Plasma keeps evolving
531382025-07-04 14:42:01.894rhenriques1.3417Straight repeat | Cycles failling but conditioning keeps improving
531372025-07-04 14:37:49.233rhenriques1.34.117Repeat | Cycles failling but conditioning keeps improving
531362025-07-04 14:33:51.604rhenriques1.3417Straight repeat | Maybe more pusles failing, conditioning seems to be improving
531352025-07-04 14:28:16.352rhenriques1.3417Repeat with 50 cycles | OK, some cycles started to fail
531342025-07-04 14:23:03.989rhenriques1.34.217Repeat with 40 cycles | All cycles successful
531332025-07-04 14:18:15.625rhenriques1.33.817Repeat #52294 (20 cycles) with controlled Ip at 1.3 kA | Good, all cycles are successful and well controlled
531322025-07-04 14:10:50.23rhenriques-1.564.1817Repeat with 20 cycles | Some cycles failed towards the end
531312025-07-04 14:06:41.154rhenriques-1.233.8817Repeat 52005 for cleaning (10 cycles) | Good, all cycles successful
531302025-07-04 13:59:33.703rhenriques-0.983.526Straight repeat for comparison of evolution | Ip is increasing
531292025-07-04 13:54:34.30rhenriques-0.823.126Straight repeat for comparison of evolution | Still low Ip, but slightly better than previous
531282025-07-04 13:49:15.048rhenriques0.642.726Repeat with lower pressure than in 53126 | Better, but still very low Ip
531272025-07-04 13:42:55.358rhenriques-0.443226Repeat with higher prefil (aiming at 2e-5 mBar at the Adm) | Still low Ip, pressure close to expected
531262025-07-04 13:34:33.555rhenriques-0.62.726Repeat with lower prefill pressure | Finally, some plasma but very low Ip. Prefill pressure seem to be low.
531252025-07-04 13:27:20.311rhenriques000Repeat by setting prefill gas based on Admission pressure instead of Main Chamber (aiming at 3e-5 mBar at Adm), with adv. config. as 53101 | No plasma despite PF currents looking OK, preffill too high
531242025-07-04 13:12:49.123rhenriques000Repeat after checking the GIS for faults | Relation between MC and Adm pressures is very different than nominal (sign of impurities?), Advanced configuration was set for breakdown, no plasma
531232025-07-04 10:30:37.401rhenriques000Repeat (1) 53101 to assess max Ip and wall conditioning (after RFA opening to MC and power outage) | Could not get correct prefill pressure on time again, no plasma
