CIT burn control using auxiliary power modulation

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 approximately 65 can be obtained. The effect of the delay time tau /sub d/ of the feedback system is investigated, and the tradeoffs between the tau /sub d/ and the maximum allowable temperature fluctuation are determined.<
