Radio frequency driven multicusp sources (invited)

The radio frequency (rf)-driven multicusp source was originally developed for use in the superconducting super collider injector. The source can routinely provide 30 mA of H∼ beam at 0.1% duty factor. By adding a minute quantity of cesium to the discharge, H− beam current in excess of 100 mA and e/H∼1 has been achieved. The rf-driven H∼ source is being further developed for 6% duty factor operation to be used in the national spallation neutron source. Application of the rf-driven multicusp source has been extended to radioactive ion beam production, ion projection lithography, and compact neutron tubes.
