The US Department of Energy Facility for Rare Isotope Beams (FRIB) at Michigan State University includes a heavy ion superconducting linac capable of accelerating all ions up to uranium with energies higher than 200 MeV/u and beam power up to 400 kW. To achieve these goals with present ion source performance it is necessary to accelerate simultaneously two charge states of uranium from the ion source in the first section of the linac. At an energy of approximately 17 MeV/u we plan to strip the uranium beam to reduce the voltage needed in the rest of the linac to achieve the final energy. Up to five different charge states are planned to be accelerated simultaneously after the stripper. The design of the stripper is a challenging problem due to the high power deposited (approximately one kW) in the stripper media by the beam in a small spot. To assure success of the project we have established a research and development program that includes several options: carbon or diamond foils, liquid lithium films, gas strippers and plasma strippers. We present in this paper a summary of the requirements and a general description of the status of the different options.

This talk will review current and possible new methods for accelerator-based production of medical isotopes. It will cover isotopes produced commercially, mostly by relatively low energy accelerators, and isotopes produced by government-operated facilities, usually by higher energy accelerators. Prospects for the production of traditionally reactor-produced isotopes such as 99Mo via accelerator-driven methods will also be discussed. Also, the special case of accelerator production of alpha-emitting isotopes for radio-immunotherapy will be reviewed.
