Notes:
The development of the RIST tantalum foil target for the production of radioactive nuclei by bombardment with energetic (∼1 GeV) proton beams of high intensity (100 μA) has shown that targets capable of dissipating 20–60 kW of thermal power can be constructed. Tantalum is a good material for high power dissipation because, as a metal, it has a relatively good thermal conduction and is able to stand very high temperatures. However, for a full range of unstable beams, it will be necessary to have targets made from many different materials. Developments of high power target and ion source designs are discussed with particular emphasis on non-metallic, non-refractory powder and liquid target materials. Also, the possibilities of combining targets and ion sources to reduce effusion times are considered, as well as methods to increase the surface-desorption rates of the radioactive particles. © 1998 American Institute of Physics.
