520272025-03-26 18:57:23.402rhenriques1.263.2817Repeat | OK
520262025-03-26 18:52:08.839rhenriques1.43.3417Repeat | lower prefill pressure and much higher current at first semi-cycle, then mostly the same
520252025-03-26 18:43:54.735rhenriques-1.053.217Repeat with lower prefill aiming at higher plasma current | OK, large Ip in first cycle, then almost no difference
520242025-03-26 18:30:49.059rhenriques-13.217Repeat with lower prefill aiming at higher plasma current | OK, a bit more Ip
520232025-03-26 18:14:48.338rhenriques-0.933.2617Repeat with filament voltage back to standard value approx. 11.5 V | OK, but prefill was already a bit lower than the other pulses
520222025-03-26 18:02:08.134rhenriques-0.933.2517Straight repeat | OK
520212025-03-26 17:57:59.721rhenriques-0.913.1917Straight repeat | OK, 1st semi-cycle is back
520202025-03-26 17:53:56.829rhenriques0.83.3617Repeat with filament voltage at approx. 7.5 V | No breakdown for 1st positive semicycle
520192025-03-26 17:48:37.274rhenriques-0.9523.117Repeat with filament voltage at approx. 2.5 V | OK
520182025-03-26 17:39:19.083rhenriques-0.913.0717Repeat to adjust prefill pressure | OK
520172025-03-26 17:31:12.795rhenriques-0.873.1217Straight repeat | OK, but prefill gas was much higher, breakdown for 1st semi-cycle is back
520162025-03-26 17:26:00.33rhenriques-0.9033.417Repeat with filament voltage at approx. 5.5 V | Breakdown of 1st positive cycle did not happened, started with negative cycle
520152025-03-26 17:17:59.847rhenriques-0.913.1417Repeat for filament test: filament voltage at 0 V. Filamente voltage acquire in RT2_24 channel | OK, breakdown started later
520142025-03-26 17:08:48.475rhenriques-0.8683.1317Repeat for repeatability | Good
520132025-03-26 17:04:15.087rhenriques-0.9073.0817Repeat to check repeatability | OK
520122025-03-26 16:49:38.032rhenriques-0.9353.117Repeat plasma pulse #52007 (20 semi-cycles) | OK
520112025-03-26 14:35:26.859rhenriques000Repeat | OK
520102025-03-26 14:09:52.402rhenriques000Repeat with TF and PF currents ON and all channels normally connected to the diagnostics (short removed) | OK
520092025-03-26 13:34:20.996rhenriques000Repeat with new calibrations for all calibrated channels: RT1_25-32, RT2_9_16_17-28. All channels have input shorted (0 V) to test offset calibration | All seem OK
520082025-03-26 11:56:01.567rhenriques000Dryrun (file: dryrun_standard_2025_03_26_52008.cfg), no TF or PF currents, test acquisition system (RT1_ch25-32) with new calibration | Forgot to update offset for RT1_26, other than that OK
