Review of work related to ion sources and targets for radioactive beams at Argonne

A group including many ANL Physics Division staff and ATLAS outside users has discussed possibilities for research with radioactive ion beams and prepared a working paper entitled ''Concept for an Advanced Exotic Beam Facility Based on ATLAS.'' Several subgroups have been working on issues related to ion sources and targets which could be used in the production and ionization of radionuclides with high power primary beams. Present activities include: (a) setting up an ion source test stand to measure emittances and energy spreads of ISOL-type ion sources, (b) experiments to evaluate methods of containing liquid uranium for production targets, (c) experimental evaluation of geometries for the generation of secondary neutron beams for production of radionuclides, (d) setting up an ISOL-type ion source at a neutron generator facility to measure fission fragment release times and efficiencies, and (e) computer simulations of an electron-beam charge-state amplifier to increase the charge states of 1(+) secondary beams to 2, 3, or 4(+). The present status of these projects and future plans are presented in this report. (C) 1996 American Institute of Physics.
