ABSTRACT:
An electron discharge device includes an evacuated envelope having therein a photocathode, an anode and an electron multiplier. The electron multiplier comprises a plurality of dynodes having a nickel substrate, an exposed surface of which has a base layer of antimony sensitized with the vapors of a plurality of alkali metals. At least one Nichrome dynode, substantially devoid of secondary emissive material is disposed adjacent to the anode. The Nichrome dynode reduces and stabilizes the anode sensitivity and gain of the device.
