Characteristics of an intense neutron source based on the d + Be reaction
A neutron source designed for fusion-related radiation damage studies has been built based on the d + Be reaction. Using a 40 MeV, 20 ..mu..A deuteron beam from the Oak Ridge Isochronous Cyclotron neutron fluxes of 1 - 2 x 10/sup 12/n/cm/sup 2//sec are obtained over an area approx. 50 mm/sup 2/. The design of the source is described, together with time-of-flight and activation foil measurements of the thick target neutron yields from the /sup 9/Be(d,n) reaction for the angular range from 0 to 90/sup 0/. A dosimetry procedure based on these measurements is presented. In addition time-of-flight measurements of the thick target neutron yields for the Li(d,n) reaction are reported and compared with the /sup 9/Be(d,n) results.
