Abstract40063 November 4, 1996 Amparo Corporation First-generation radioactive beam facilities, in use or under construction, cannot completely address many of the scientific opportunities envisioned until an intense production beam is employed. This project addresses a key element in filling this need, the design of high power nuclear targets. The targets will be used for the production of intense radioactive ion beams from high-energy charged particle beams, especially high energy protons, and will yield a broad variety of radioactive species in intensities significantly larger than presently available. The production of isotopes in a vapor form for subsequent mass separation and acceleration will depend on the ability to control target temperature profiles within the target resulting from interactions of the intense production beams with the target material. Target materials in powder form will be used to expand employment of thermal barriers between the metallic or molten target materials and cooling systems. Actual targets, envisioned for 200-MeV proton irradiation, will be analyzed at target thicknesses corresponding to interaction lengths for the incident beam. Successful completion of the Phase I effort will lead to the possibility for construction of one or more prototype target(s) to be tested at an existing accelerator facility. Anticipated Results/Potential Commercial Applications as described by the awardee: This project should provide designs of high-power targets for testing at an existing accelerator facility, allowing for the production of intense radioactive beams.
