Abstract

A new method for the production of highly charged ions is proposed. The ions are produced in local potential traps formed by the rippled electron beam in a focusing magnetic field. The electron current density can reach extremely high values of the order of 10 kA/cm2 on a short length of the ion trap. Based on this method, a family of hand-size ion sources and traps with electron beam energy ranging from a few tens of eV up to a few tens of keV has been developed. The devices are classified as MaMFIS/T (main magnetic focus ion sources and traps). The novel ion sources offer many applications in atomic physics, plasma physics, solid-state physics, single ion implantation, ion lithography, cancer therapy and elsewhere.
