The report is concerned with an analysis of the problems involved in the design and slection of equipment for the production of intense beams of 14-MeV neutrons. Since the aim is to achieve total neutron yields in excess of 10 to the 13th powersec, a figure which considerably surpasses that commonly encountered with currently operating accelerators, it is necessary to extrapolate present performance to a considerable degree. Low-voltage accelerators in operation at the present time rarely produce DC beam currents in excess of 1 mA currents of 600 micro amps. are considered high. The production of neutron yields of 10 to the 13th powersec will require beam currents greater than 10 mA. This is a significant increase and gives rise to problems of ion source design, source cooling, beam optics, target preparation, mechanical target desgn, etc. These problems are analyzed individually and certain conclusions are reached and recommendations are made.
