Preliminary Analysis of Volt-Second Consumption on HL-2M

Prediction of volt-second consumption has been done by the tokamak simulation code (TSC), which includes the whole plasma discharge of HL-2M conception design. It covers the volt-second consumptions at the entire current ramp-up phase and the plasma flattop phase. More important, the sensitivities of volt-second consumption with respect to the current ramp-up time and the impurity concentration have been studied, respectively
