522512025-04-10 18:24:29.533rhenriques-1.383.817Repeat at higher prefill pressure ~1e-4 mBar | OK
522502025-04-10 18:20:31.448rhenriques-1.4653.8917Repeat | OK
522492025-04-10 18:16:17.876rhenriques-1.4753.8117Repeat | OK
522482025-04-10 18:12:11.92rhenriques-1.4463.8417Repeat | OK
522472025-04-10 18:07:35.291rhenriques-1.4963.9317Repeat with signals back to their original position | OK, signals are OK
522462025-04-10 17:59:19.611rhenriques-1.4463.817Repeat, swap fiber_optic_with_filter with photodiode_visible signal at acquisition channels to check the fiber one which suddenly lost a lot of amplitude | Both signals have the correct amplitude
522452025-04-10 17:46:04.207rhenriques-1.413.617Repeat | OK
522442025-04-10 17:41:33.97rhenriques-1.4883.8617Repeat | OK
522432025-04-10 17:33:07.354rhenriques-1.4643.917Repeat with lower prefill (as in reference pulse) | OK
522422025-04-10 17:26:58.671rhenriques-1.3043.6217Repeat | OK
522412025-04-10 17:18:45.439rhenriques-1.283.717Plasma pulse, repat 52232 with normal prefill pressure ~1e-4 mBar | OK, signal from fiber_optic_with_filter (O I line) is significantly lower than reference pulse
522402025-04-10 17:10:47.934rhenriques000Repeat with cables back to normal position and after having fiddled with the module | Looks better but it is still more noisy than the other ones
522392025-04-10 16:49:36.712rhenriques000Repeat, connecting back to 2nd ATCA and swaping cable in MARTe 1 ATCA: coil no. 1-8 to RT3_9-17 and 9-12 to RT3_25-28 | Noise comes from the integrator module
522382025-04-10 16:41:03.663rhenriques000Repeat with connection to 2nd ATCA (MARTe 2) crate module removed | Did not improve
522372025-04-10 16:32:57.218rhenriques000Repeat to check if coil no. 2 signal is less noisy after cable checking. Request of 300 A | Better but coil no. 2 is still noisy
522362025-04-10 16:21:22.336rhenriques000Repeat with lower request (280 A) | Good, signal of coil no. 2 is noisy
522352025-04-10 16:14:22.559rhenriques000Special dryrun with long Vertical PF current only, for Magnetics diagnostics calibrations | OK, but current never reaches the request and keeps decreasing throughout the pulse
522342025-04-10 16:08:04.364rhenriques000Repeat with lower request (100 A) | Good
522332025-04-10 15:58:31.629rhenriques000Special dryrun with long Horizontal PF current only, for Magnetics diagnostics calibrations | Good, did not reach the request (200) but was quite stable
