Engineering Physics Annotation << Back KARAT NUMERICAL SIMULATION OF CAPACITIVE RF DISCHARGE IN EXTERNAL RADIAL MAGNETIC FIELD I.I. ZADIRIEV, A.A. RUKHADZE, E.A.KRALKINA, V.B. PAVLOV, K.V. VAVILIN, V.P. TARAKANOV Numerical simulation of capacitive RF discharge in Hall ion source geometry has been carried out. It is shown that closed azimuthal electron drift and drop of time averaged electric potential appears near ion source channel’s edge. That potential drop causes formation of accelerated ion beam on the exit of discharge channel. Key words: capacitive RF discharge, radial magnetic fi eld, particle-in-cell, Hall ion source.
