518922025-03-06 20:27:41.444rhenriques0.78200Repeat for comparison | OK
518912025-03-06 20:22:27.768rhenriques0.76900Repeat previous | OK
518902025-03-06 20:18:27.932rhenriques000Repeat with reduced spectrometer gain (80) and longer integration time (500, instead of typical 200 ms) | MARTe failed
518892025-03-06 20:14:29.808rhenriques0.7500Repeat with reduced spectrometer gain (20) and longer integration time (500, instead of typical 200 ms) | OK, with longer integration time we see more lines (which may appear towards end of pulse)
518882025-03-06 20:09:56.011rhenriques0.74800Repeat with reduced spectrometer gain (40) and longer integration time (500, instead of typical 200 ms) | OK
518872025-03-06 20:05:48.992rhenriques0.73600Repeat with reduced spectrometer gain (50) and longer integration time (500, instead of typical 200 ms) | OK, interesting data on spectrometer
518862025-03-06 19:59:05.295rhenriques0.73600Repeat with reduced spectrometer gain (1) and integration time (40, insteado of typical 200 ms) | OK
518852025-03-06 19:54:13.995rhenriques000Repeat with reduced spectrometer gain (1) | OK
518842025-03-06 19:50:09.302rhenriques000Repeat with reduced spectrometer gain (10) | OK
518832025-03-06 19:45:35.226rhenriques0.68700Repeat with reduced spectrometer gain (50) | OK, but Halpha line still saturates
518822025-03-06 19:40:45.71rhenriques0.67200Repeat | OK, spectrometer data different than previous
518812025-03-06 19:35:26.475rhenriques0.8200Repeat | prefill was much lower
518802025-03-06 19:30:41.296rhenriques0.66500Repeat | OK
518792025-03-06 19:26:18.357rhenriques0.64700Repeat | No clear conclusions but some evolution is obsereved on spectrometer data
518782025-03-06 19:21:35.804rhenriques0.63800Repeat | Mostly the same but data from spectrometer looks different
518772025-03-06 19:17:14.705rhenriques0.64500Repeat with 20 semi-cycles to assess conditioning improvements | OK
518762025-03-06 18:46:33.648rhenriques0.61400Repeat with adjustment on horizontal field for Ip>0 | Different but not necessary better
518752025-03-06 18:37:22.378rhenriques000Repeat with changes on Bv for Ip>0 | better flatop
518742025-03-06 18:23:35.934rhenriques78400Repeat with further adjustments on Bh for Ip > 0 | Slightly better
518732025-03-06 18:18:19.741rhenriques0.72400Repeat with correction on Bh for Ip > 0 only | Better but still far from centered position
518722025-03-06 18:11:50.677rhenriques-0.52900Repeat with adjustment on horizontal field for both Ip (+ and -) | negative cycle better and positive cycle worst
518712025-03-06 17:59:50.12rhenriques-0.52300Repeat with ajustments to waveforms for Ip>0 | Got all cycles but at rather lower current
518702025-03-06 17:48:21.627rhenriques-0.72400Repeat 51868 | Better than reference, prefill slightly lower
518692025-03-06 17:32:57.15rhenriques000Dryrun to check magnetic diagnostics and time base delay of MARTe signals | MARTe timebase delay is now back to normal value (-1 ms), no signals on Magnetics
518682025-03-06 14:33:32.902rhenriques-0.700Repeat | Higher prefill than previous pulses
518672025-03-06 14:28:47.419rhenriques-0.77400Repeat aiming prefill level closer to reference | Much better, almost as reference
518662025-03-06 14:20:17.083rhenriques-0.3400Repeat 51855 to assess plasma condition | Only got 2 negetive semi-cycles, prefill was significantly lower than in reference pulse
