FIELD: electronics; ion beam generation. SUBSTANCE: electron beam and primary ion beam are produced between target and probe by sequential impact with direct electrical, magnetic, and reverse electric fields; after that substrate is placed between target and probe and electric field impact is provided again, target and substrate being electrically interconnected in advance; after that secondary ion beam is produced. EFFECT: enhanced focusing of beam at low intensity of straight-directivity ion beam. 1 cl, 2 dwg
