Abstract

A compact ionization chamber-first stage unit for the detection of alpha particles and protons which has low sensitivity to mechanical vibration and high signal to noise ratio has been constructed, using a metal tube (6J7) which supports the collector plate of the ionization chamber directly on its grid cap, thus eliminating the usual flexible lead. This construction makes it possible to mount the entire unit in the position formerly occupied by the ionization chamber alone and dispense with any vibration-damping suspension for the tube.
