Title: ION PRODUCING MECHANISM

Abstract

This patent relates to improvements in calutron devices and particularly describes a novel ion source. The unique feature of this source lies in the shaping of the ionizing electron stream to conform to the arc plasma boundary at the exit slit of the ionization chamber, thereby increasing the ion density produced at the plasma boundary. The particular structure consists of an electron source disposed at onc end of an elongated ionization chambcr and a coilimating electrode positioned to trim the electron stream to a crescent shape before entering the ionization chamber.
