Abstract
An iris for a stage of a receiver protector is described incorporating a metal plate having a slot opening wherein the electric field across the slot opening is enhanced by tapering or beveling the edges of the slot. The invention overcomes the problem of high firing threshold and high recovery time of a gas plasma by providing metal in close proximity to the gap for providing free electrons.
