Humphries, S Jr

The reflex triode pulsed ion accelerator, developed at Cornell, has successfully produced equivalent proton output currents in excess of 6 kiloamperes at 20 amps/cm$sup 2$ for pulse lengths of about 50 nanoseconds. Energies up to 300 keV have been investigated with maximum energy conversion efficiencies of 42 per cent. The principles of operation with mesh anodes are discussed with a review of current experimental results. A theory of triode operation at high energies using plastic foil anodes is presented. The model indicates that it may be possible to achieve efficiencies near unity and ion current densities in excess of the Langmuir-Child limit. An accelerator under construction in which it is hoped to obtain over 50 kiloamperes at 3 MeV is discussed. (auth)
