Abstract
The plasma switching stage of a radar receiver protector is simplified and improved by the utilization of a halogen gas filled quartz container and a 'keepalive' electron source. The container is configured as a capillary stem filled with low pressure chlorine gas and provides the active switching element in the signal waveguide portion of the receiver protector. An enclosed r.f. energy source in combination with the capillary stem creates a copious and steady free electron supply. The r.f. exciting field used to activate the 'keepalive' plasma is enhanced by a coaxial re-entrant cavity located on the top wall of the receiver protector waveguide.
