Shot Time Operator Iplasma(kA) n(1018m-3) Duration (ms) Pre/post shot comments
516212024-12-19 20:02:52.223rhenriques000Repeat (Iprim on B3ch2 and Vprim on B3ch1) with longer ON time of 13 ms | OK, current shoots up after iron core saturation
516202024-12-19 19:47:48.981fernando000Repeat with capacitor bank voltage at 200 V, with 10 ms long | OK, iron core almost started to saturate
516192024-12-19 19:35:14.713rhenriques000Repeat (primary bank voltage programmed for 60 V) | OK, but current in primary very low as expected...
516182024-12-19 19:06:10.616rhenriques000Primary PF coil with 10 ms always ON | no current in Primary, probably MARTe was not loaded with new config
516172024-12-19 18:38:49.272rhenriques000Repeat previous (Iv on B3ch3 and Vv on B3ch7) | OK, satuaration reached at 113 A
516162024-12-19 18:34:34.18fernando000Repeat previous with 13 ms flatopt | MARTe problem, no currents on the coils
516152024-12-19 18:24:48.369rhenriques000Repeat with lower power supply voltage (12 V) to aim a saturation a avoid switching | OK, but never saturates
516142024-12-19 17:44:52.303fernando000Repeat previous | OK, reach 200 A quite early starts switching
516132024-12-19 17:37:22.485rhenriques000Vertical PF coil with 5 ms always ON | MARTe failed
516122024-12-19 17:15:50.605rhenriques000Horizontal PF coil (Ih on B3ch4 and Vh on B3ch8) with 13 ms always ON | OK, almost constant at the end
516112024-12-19 16:55:54.92rhenriques000calibration of B3 ch4 and ch8 with +/-2V, no current on PF coils |
516102024-12-19 16:30:37.616rhenriques000chopper modules MARTe1 ATCA connected to pickup coils, B3 ch1 and ch3 with +/-2V reference waveform for calibration | OK
516092024-12-19 15:43:52.866rhenriques000Chopper modules of MARTe 1 ATCA crate with +/- 2V square signal (30ms period) and same signal in B3 ch2 and ch7 for calibration, magnetic signals acquires by ATCA2 chopper modules |
