Abstract

In one embodiment of a compact closed-drift ion source, an ionizable gas is introduced into a annular discharge region. An anode is at one end of this region and an electron-emitting cathode is near the opposite and open end. A
magnetic circuit extends from an inner pole piece to an outer pole piece, with both pole pieces near the open end. The electron current in the discharge region interacts with the magnetic field therein to generate and accelerate ions out of the open end. A permeable enclosure surrounds the anode end of the discharge region. Adjacent elements of the permeable enclosure, the inner pole piece, and any intermediate permeable elements are in close proximity, one to the next. A magnetizing means is located only between the outer pole piece and the permeable enclosure.
