Title: ION SOURCE UNIT FOR A CALUTRON

Abstract

An improvement in the ion-producing mechanism for use in a calutron is described. In its broad aspects the improvement comprises the addition of shieid plates between the electron emitting filannent of the ion source and the ionization chamber. An aperture in one of the shields provides a path for electrons from the filament to enter the ionization chamber of the source block. As the shield members are electrically connected to the negative side of the filament power supply, the favorable action of the upper shield is to prevent the electron bombardment of all the elements of the calutron which overlie the filannent, and the lower shield member con fines the emission of electrons from the filannent to a relatively short segnnent, thereby increasing the life of the filannent.
