STABILITY OF THE HIGH-CURRENT ION BEAM IN DRIFT GAP OF LINEAR INDUCTION ACCELERATOR

The results of numerical simulation of compensated ion beam (CIB) transport with current density 9 MA/m(2) through the drift gap of a linear induction accelerator (LIA) are presented. The CIB stability for the three methods of compensation in the charge of the ion beam in the absence and presence of an external magnetic field is considered. It is shown that in the presence of an external magnetic field instabilities development does not lead to a significant deterioration in the ion beam quality regardless of the compensation way. It is shown, that the most effective addition compensation of the ion beam in charge is applying of self-consistent injection of additional electrons, which leads to the conservation of the CIB parameters, sufficient for its use in heavy-ion inertial fusion (HIF).
