REFLECTION OSCILLATOR Russian patent published in 1996 - IPC

FIELD: electronic devices, microwave oscillators. SUBSTANCE: multiple-resonance reflection oscillator has magnetic focusing unit which is located in vacuum and has permanent ring magnets. Ring cathode is used as electron source. Device has ring resonators. Ring permanent magnets are arrange in pairs around through channel (on both sides of ring electron flow). Said magnets may be located at input and output of electrodynamic system and at least between two resonators of oscillator as well as between resonators of given period. Device may be used for microwave devices with ring, high-rate electron flow, ring resonators and magnetic focusing system which is located in vacuum. EFFECT: decreased supply voltage (or increased output power), decreased size, decreased weight, increased efficiency. 3 cl, 1 dwg
