Abstract

Recent years have seen extensive research into cold cathode magnetron injection guns of ordinary and inverted type. Such sources employ secondary emission in crossed electric and magnetic fields. Among their merits are long operating life, high current density, relatively simple configuration, the capability of producing hollow beams, etc. Therefore, they could make emitters for long-lived high-power microwave generators or fast high voltage devices Offering intense electron beams, these guns enable one to achieve high levels of pulse power when used in klystrons or other microwave tubes
