COLLECTOR WITH MULTI-STAGE RECOVERY FOR AN ELECTRONIC GYROTRON-TYPE UHF APPARATUS Russian patent published in 2021 - IPC H01J23/27 

FIELD: electronics.

SUBSTANCE: invention relates to electronic technology, namely to collectors with energy recovery in electro-vacuum microwave devices. The technical result is an increase in total efficiency by increasing the efficiency of multi-stage recovery and reducing the current reflected from the collector, and increasing the service life of the device by reducing the thermal load on the collector electrodes. To create an azimuthal magnetic field, a toroidal solenoid is used, the end conductors of which are assembled into bundles from the side from which the electron flow enters the collector to increase the flow of electrons passing into the recovery area.

EFFECT: increase in the efficiency of recovery and a decrease in the flow of electrons reflected from the collector is achieved by reducing the spread of the radial position of the leading centers of the electron trajectories at optimal parameters of the toroidal solenoid, as well as through the use of a partitioned electron flow.
