Advanced Ion Source

The analytic and experimental studies conducted during Phase 1 of the program indicate that it is possible to design both cesium and iodine sources to meet the specified brightness requirements of 200 and 100 A/cm squared sr respectively. No reasons were uncovered as to why these two types of sources cannot operate in the same vacuum environment in such a manner that the ion species available to the AMS can be rapidly changed. Prototype hardware will be developed in Phase 2 to demonstrate this ability.
