The Fusion Materials Irradiation Test (FMIT) facility is designed to perform fusion material tests. It is basically a high-current low-energy (35 MeV) linear deuteron accelerator. The accelerated deuteron beam strikes a flowing lithium target. The interaction of the deuteron beam with the lithium generates a high neutron flux of similar magnitude and spectrum to that received by the first wall of a fusion device. It will generate both high energy (about 14 MeV peak) and high flux neutrons (>10/sup 15/ n/cm/sup 2/ sec) over sufficient volumes to test miniature material test specimens. A cutaway drawing of the test cell region of the facility in which the neutrons are produced is shown. The prime test module will be put as close as possible to the backing plate of the flowing lithium stream. In this way the maximum number of neutrons will be intercepted. The highest neutron flux region will have fluxes much higher than those in a Tokamak fusion device.
