Analysis of charged particle flows in the interelectrode gap of an ion-optical system

Abstract

The article presents the results of an experimental study and numerical simulation of argon ion flow formation in the inter-electrode gap of the ion-optical system used in a miniature linear accelerator. In the experimental study, an ion source with a Penning discharge was used to generate charged particles. The experimental results of measuring the beam emittance at the output of an ion source were used as initial data to numerically simulate the dynamics of charged-particle flows. The simulation results are consistent with those obtained via an experimental study on the trajectories and parameters of the ion flow local spot on the collector of the accelerating system.
