1. An ion source comprising:
a chamber having a first end, a second end opposite the first end, a first wall extending from the first end to the second end, and a second wall opposite the first wall;
a source filament at the first end of the chamber and configured to emit electrons and a first amount of heat;
a beam aperture at the second wall of the chamber; and
one or more heaters positioned within the chamber and between the second end and the beam aperture and operable to provide a second amount of heat;
wherein the one or more heaters are positioned and operable such that the second amount of heat balances the first amount of heat to reduce or eliminate a temperature gradient in the chamber.
