Abstract

In previous works on ICPTs with split coil [1, 2], the Authors pointed out that for a particular choice of the geometric parameters two equilibrium states for the plasma exist for the same induction coil current. In the present study, a deep investigation of the transition between the two states is performed with a time-dependent simulation code, evidencing a sort of hysteresis phenomenon. A parametric study is carried out in order to find threshold parameters for the bistability in different geometries. For some cases, time oscillating behaviour of plasma is found.
