Abstract
A device for use as a receiver protector in radar systems comprising a passive gas stage device and a waveguide opening. The passive gas stage device includes a sealed quartz container, a reactive gas filling the container and a thin film of radioactive material deposited on a flat surface of a glass rod in the interior quartz container for providing free electrons to initiate a gas discharge in the presence of high power pulses. The waveguide opening includes an iris plate having a discharge gap that is in close proximity to the film of radioactive material so that the film provides a large number of electrons in the discharge gap to initiate a gas discharge in the presence of microwave pulses.
