Abstract :
A 0-D transport model is used as a means of examining the Compact Ignition Tokamak (CIT) thermal instability. It is shown that auxiliary power modulation can be used for mapping the tokamak operating space, choosing the operating point, and for thermal stability control. Stable operation with Q~65 can be obtained. The effect of the delay time τd of the feedback system is investigated, and the tradeoffs between the τd and the maximum allowable temperature fluctuation are determined
