518642025-03-05 18:17:17.396rhenriques-0.67300Repeat | Similar to previous
518632025-03-05 18:12:43.815rhenriques-0.65700Repeat | one more good cycle than previous
518622025-03-05 18:07:57.828rhenriques-0.68600Repeat with even more prefil gas | lower current and lesser good cycles
518612025-03-05 18:02:19.339rhenriques-0.79100Repeat with a bit more prefil gas | better
518602025-03-05 17:54:59.849rhenriques-0.81100Repeat to check evolution | mostly the same as previous
518592025-03-05 17:50:24.835rhenriques-0.81200Repeat to check evolution | better
518582025-03-05 17:14:25.223rhenriques-0.79600Trying again | OK, but lack of position control reduces plasma performance
518572025-03-05 17:08:17.036rhenriques000Reverting previous changes (back to 51855) and run 40 cycles to assess if plasma is cleaning anything | MARTe failed
518562025-03-05 16:56:41.887rhenriques-0.74300Repeat with further adjustments on vertical field for Ip<0 | Got worse
518552025-03-05 16:50:39.397rhenriques-0.77600Repeat with further adjustments on vertical field for Ip<0 | Slightly better
518542025-03-05 16:40:46.637rhenriques-0.79300Repeat with corrections on vertical field and further prefill adjustments | No clear plasma position changes compared to 51852
518532025-03-05 16:33:10.581rhenriques-0.73500Repeat with further adjustements to vertical field (and ajustments on prefill too to keep it the same as previous pulses) | prefil was lower and changes in horizontal plasma position were too large
518522025-03-05 16:23:43.798rhenriques-0.74400Repeat reverting changes and adjusting vertical field | Better, flatter flattop
518512025-03-05 16:11:17.521rhenriques-0.7600Repeat with further changes on horizontal field for Ip<0 | Got worst
518502025-03-05 16:00:07.995rhenriques-0.7600Repeat with slight change on vertical and horizontal fields | Slightly better
518492025-03-05 15:46:58.416rhenriques-0.79600Repeat trying to improve plasma position after inversion (changing vertical and horizontal fields) | different results, maybe better
518482025-03-05 15:31:28.03rhenriques-0.78900Repeat trying to improve transition to Ip<0 by changing horizontal field during inversion | No clear changes
518472025-03-05 15:17:50.763rhenriques-0.7500Repeat with shortening of maximum inversion time (down to 2ms) | Better peak current
518462025-03-05 15:08:17.211rhenriques-0.3900Repeat exactly the same to assess if there are improvements | Exactly the same result
518452025-03-05 14:59:01.308rhenriques-0.3700Going back to previous configuration and changing vertical field of Ip > 0 (looking only at 1st semi-cycle for now) | Very different results, only negative cycles
518442025-03-05 14:45:53.793rhenriques-0.5100Repeat with changes in horizontal field for Ip < 0 (continue logic of previous session) | Got worst
518432025-03-05 14:30:17.839rhenriques-0.4600Repeat again | Mostly the same result as in previous pulse
518422025-03-05 14:24:11.933rhenriques-0.4800Repeat to check if there are improvements in relation to 1st pulse of the session | there are improvemens but not yet the same pulse as 51838
518412025-03-05 14:18:47.962rhenriques-0.4900Plasma pulse, repeat 51838 | Reasonably different but may be due to 1st pulse of the day
518402025-03-05 13:55:49.924rhenriques000Repeat with correct configuration (file: dryrun_standard_2025_03_03_51819.cfg) and including TF | PF and TF current all OK
518392025-03-05 13:49:37.41rhenriques000Standard dryrun as 51819 | Wrong MARTe configuration
