pulsetimings = None module-attribute

Switch for pulse timings (if i_pulsed_plant=1):

t_plant_pulse_burn = None module-attribute

flat-top duration (s) (calculated if i_pulsed_plant=1)

t_burn_0 = None module-attribute

burn time (s) - used for internal consistency

t_plant_pulse_total = None module-attribute

Total plant pulse cycle time (s)

t_plant_pulse_no_burn = None module-attribute

Plant pulse time spent not a flat-top burn phase (s)

t_plant_pulse_dwell = None module-attribute

Plant pulse dwell time before start of next pulse (s) (iteration variable 17)

t_plant_pulse_fusion_ramp = None module-attribute

time for plasma temperature and density rise to full values (s)

t_pulse_cumulative = None module-attribute

array of time points during plasma pulse (s)

timelabel = None module-attribute

array of time labels during plasma pulse (s)

intervallabel = None module-attribute

time intervals - as strings (s)

t_plant_pulse_plasma_current_ramp_up = None module-attribute

Plant pulse time for plasma current to ramp up to approx. full value (s) (calculated if i_pulsed_plant=0) (iteration variable 65)

i_t_current_ramp_up = None module-attribute

Switch for plasma current ramp-up time (if i_pulsed_plant=0): - = 0, t_plant_pulse_plasma_current_ramp_up = t_plant_pulse_coil_precharge = t_plant_pulse_plasma_current_ramp_down = Ip(MA)/0.5 - = 1, t_plant_pulse_plasma_current_ramp_up, t_plant_pulse_coil_precharge, t_plant_pulse_plasma_current_ramp_down are input

t_plant_pulse_plasma_present = None module-attribute

Plant pulse time in which a plasma is present (s)

t_plant_pulse_plasma_current_ramp_down = None module-attribute

Plant pulse time for plasma current, density, and temperature to ramp down to zero, simultaneously (s); if pulsed, = t_plant_pulse_plasma_current_ramp_up the CS and PF coil currents also ramp to zero at the same time

t_plant_pulse_coil_precharge = None module-attribute

the time for the central solenoid and PF coils to ramp from zero to max current (s); if pulsed, = t_plant_pulse_plasma_current_ramp_up
