Multiple uses of an upgraded FMIT facility
The Fusion Materials Irradiation Test (FMIT) facility has been designed to test small samples in neutron environments similar to fusion reactors. The source of neutrons would be a 0.1 A beam of 35 MeV deuterons stopped in a liquid lithium jet target. During the present construction deferral, pending an international agreement, an expanded mission is being explored. Multiple beams in a common accelerator structure could be used to obtain a total steady state beam current of about 1 A. For fusion materials, the individual beams could be directed to several FMIT targets, or the beams could be combined for testing of multi-liter sized components of fusion reactors. An additional use would be to provide a high flux source of thermal neutrons for basic research in condensed matter. A steady state flux of 10/sup 16/ n/cm/sup 2/-s thermal neutrons is desired. This would be an order of magnitude improvement over current reactor sources. Such a flux can be achieved with a beam current of 0.1 A and an energy less than 300 MeV upon a Pb-Bi target. This could be obtained from a booster linac fed by one of the multiple beams at 35 MeV. Details of the uses will be discussed.
