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

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, 130{μ}a 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.
