Application of a new algorithm to plasma shape control in BPX

A new shape control algorithm has been tested by numerical simulation of a tokamak discharge in the Burning Plasma Experiment (BPX), using the TSC code. The algorithm controls the plasma shape and current according to a preprogrammed scenario without using any precalculated coil current waveforms. If the plasma parameters (heating scenario, density evolution, effective charge, etc.) change, the algorithm automatically maintains the given shape evolution and does not have to be readjusted. This allows independent programming of plasma current, density, heating power, shape and position.
