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.

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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
