Shot Time Operator Iplasma(kA) n(1018m-3) Duration (ms) Pre/post shot comments
518042025-02-27 19:15:10.696rhenriques000Repeat with inversion to Ip < 0 back to normal as in #51798 and adjusted vertical waveform for positive cycle to optimize inversion to Ip < 0 | MARTe failed
518032025-02-27 18:53:27.229rhenriques-0.3900Repeat with waveform going in opposite direction than previous pulse | Not clear if it is better
518022025-02-27 18:45:11.333rhenriques000Back to 7000 us of max inv. time and tweak on Inversion waveform for horizontal field for transition to Ip < 0 | Got worst
518012025-02-27 18:28:40.974rhenriques-0.4600Repeat with max inversion time set to 2000 us | Similar results as previous
518002025-02-27 18:21:14.228rhenriques-0.4800Repeat with correct maximum inversion time 1500 us | Inversions got worse
517992025-02-27 17:57:08.884rhenriques-0.3602Repeat but with 8 cycles only and max inversion time down to 1500 us (instead of 7000 us) | maximum time was 15000 us, by mistake
517982025-02-27 17:49:30.652rhenriques-0.4500Repeat | OK, but pulse was programmed with 40 cycles
517972025-02-27 17:43:44.698rhenriques000Repeat previous, LP for positions in B3ch25(bottom), B3ch26(HFS), B3ch27(top) and B3ch28(LFS) | MARTe failed again, reason is unclear
517962025-02-27 17:37:35.424rhenriques000Try plasma, repeat #51783, with position Langmuir Probes acquired in 2 MSps, B3 ch. 25 to 28 | MARTe did not run because of wrong PS communicator addresses
517952025-02-27 16:54:32.698rhenriques000Repeat to check Toroidal Field PS and current | OK
517942025-02-27 16:10:55.758rhenriques000Dry run with on-coil PF and TF currents. Gas puff not expected to happen althoug programmed (to be checked at a later stage) | OK, but TF PS for cleaning was also connected to TF coils (breaker ON)
517932025-02-27 15:54:35.566rhenriques000Repeat with adjusted zero points for current measurements, Primary PS: 511->510, Vertical PS: 511->509 and Horizontal PS: 511->510 | Good
517922025-02-27 14:57:15.458rhenriques000Test dry run pulse as an informatic pulse only (no PF currents on the coils) | OK, gas puff does not seem to be working
