Title: SECONDARY ELECTRON MULTIPLIERS

Abstract

A secondary emission multiplier having exceptionally high output signal current is described. In previous multiplier tubes the output signal current was limited by the space charge surrounding the electrodes. The present multiplier tubes provides a source of ions within the tube adjacent the anode to neutralize the space charge effect, and the dynode voltage is switched on intermittently for periods of time so brief that the ions do not move towards the cathode.
