Abstract
A low energy proton source for non-neutral plasma experiments was developed. Electrons from a hot filament ionize H gas inside a geometrically compensated Penning trap to produce protons via dissociative ionization. A rotating wall electric field destabilizes the unwanted H and H generated in the process while concentrating protons at the center of the trap. The source produces bunches of protons with relatively low ion contamination (5.5% H and 15.5% H), with energy tunable from 35 to 300 eV.
