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.
Claims11
A passive gas stage device for use in a receiver protector in radar systems comprising:
- a sealed quartz container;
- a quartz rod within said container, said rod having at one end a surface with a perimeter and at an opposite end a cap with a perimeter larger than the perimeter of said surface;
- a radioactive film on said surface of the rod;
- and
- a reactive gas filling said container, said gas being capable of ionization in response to a microwave pulse for fast recovery time performance.
