The design and fabrication of a high-intensity, 14-Mev neutron source which can be operated on a hoist platform on the 1500-ft BREN tower at the Nevada Test Site (NTS) has been determined to be feasible. Utilixing the Y(d,n)4He reaction, the source should be capable of producing, as a minimum, an average intensity of 10 13 neutrons/sec for periods up to 4 hr. The type and placement of power supplies, ion sources, targets, and vaccum eqipment have been examined and a preliminary conceptual design completed. Control system, testing procedures, and construction operations were studied and are presented. It is estimated that the neutron source will cost from 260,000 to 300,000 occupy approximately 400 ft3 weigh approximately 7.5 tons and require about 10 months to complete.
