Extraction of the ion beam from hollow cathode ion source. Experiment and computer simulation

The experimental measurements and computer simulation results of the intensity of the Ar+ ion current emitted from the hollow cathode ion source as a function of extraction voltage are presented in the paper. The computer simulations of the phenomena inside the ion chamber and ion beam formation were done using modified version of the TRQR code based on particle-in-cell (PiC) method. The agreement between experiment and calculated results is quite good.
