Some Features of an Electrostatic Generator and Ion Source for High Voltage Research

Abstract

A compact generator of the Van de Graaff type is described in which several new features have been incorporated. Short-circuit current of one milliampere is available. When operating at 600 kv as voltage supply for accelerating protons or deutersons, 130μa of charged particles at the target have been obtained from an unusual low voltage capillary arc source. In normal operation as a neutron generator, the equivalent of 15 curies of radon-beryllium is readily produced by the reaction Li+D, and 60 curies by the D on D reaction.
