Numerical modeling of high current ion beam transport with additional injection of electron beams in drift and accelerating gaps of LIA

摘要

The dynamics of a high-current ion beam (HCIB) in the system, consisting of magneto-isolated accelerating gapudand the drift gap (DG) of the experimental model of linear induction accelerator (LIA) has been studied. The optimizationudof the magnetic field geometry, the place and time of the additional electron beam injection, as well as itsudcross dimension is occurred. It is shown that at found parameters of the beams, the external magnetic field, the injectionudof the main and additional electron beams, HCIB can be compensated (HCIB and an additional electron beamudcurrents practically equal to the initial values and are equal to each other), so that at the exit from the system, ionudbeam parameters are suitable for a number important technological applications.
