Multiple uses of an upgraded FMIT facility

Conference ·
OSTI ID:5539082

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.
