The scattering of fast neutrons by lead. Construction of an ion source and accelerating tube

Abstract

Many new ideas have been tried in the search of ion sources with greater output. One of the best announced in recent years is an ion source designed by A. T. Finkelstein and described in the "Review of Scientific Instruments". One of the purposes of the work discussed in this paper was the adaption of an ion source of the Finkelstein type to the Rice Institute Cockcroft-Walton high voltage particle accelerator. In previous experiments with the Cockcroft-Walton set, the voltage obtained was limited by breakdown across the single accelerating gap. The second purpose of the work was to eliminate this limitation by substitution of a set of multiple gaps for the single one.
