- The preliminary design of an accelerator suitable to meet the flux and neutron energy requirements of a CTR materials test facility is presented. The specifications of such a facility call for a neutron flux of 10/sup 14/ n/cm/sup 2/-sec distributed over an area of about 10/sup 2/cm/sup 2/ with a neutron spectrum similar to that anticipated from a fusion reactor. A 30 MeV deuteron linac producing a CW beam of 125 mA, upgradable to 40 Mev at 250 mA at a later date, would produce the relatively broad spectrum of neutrons at the required intensity. Beam dynamics at the required current dictate an injection energy of 750 keV and a frequency of 50 MHz. The average axial field of 1 MV/m results in a wall power density of slightly less than the Super-HILAC at full gradient and 30% duty factor. Each of the seven cavities will have its own 800 kW rf power source for a 125 mA beam intensity, expandable to 250 mA by doubling the number of rf sources. Attention to the low-energy beam intercept on the drift tubes and diffusive losses producing neutrons and attendant activation problems are discussed.
