A High Current Pulsed Ion Source for Metallic Ions

A new sputter-ion PIG source and magnet system, optimized for intermediate charge states, q/A of 0.02-0.03, is described. This source will be used with the new Wideroe-based injector for the SuperHILAC. Pulsed electrical currents of several emA of heavy metal ions have been produced in a normalized emittance area of .05¿ cm-mr. The source system is comprised of two electrically separate anode chambers, one in operation and one spare, which can be selected by remote control. The entire source head is small and quickly removable.
