METHOD FOR FORMING HIGH ENERGY DENSITY CLUMPS IN ELECTRON FLOW AND A DRIFT KLYSTRON Russian patent published in 2018 - IPC H01J25/00 

FIELD: electronic equipment.

SUBSTANCE: invention relates to electronic microwave equipment, in particular, to powerful microwave O-type devices. Methods for forming clusters of high energy density in an electronic clump formed by an electron source, in which the formation of clumps subjected to final grouping before they exit from a number of microwave fields, can be realized in a transit klystron by stepwise modulating the velocity and density of electron distribution in an electron beam, in the nuclei of electron clumps by means of the influence of a number of microwave fields on the electron beam. In this case, the microwave fields are sequentially located in the direction of the flow and are separated by drift spaces. Clump of electrons is passed through a cascade of microwave fields containing at least one multi-resonator stage, which provides, in turn, the formation of a clump nucleus, increase in the density of the clump nucleus, ungrouping of the clump nucleus, and a final grouping of the clump.

EFFECT: achievement of a high current density in a clump, directed at the braking to convert its energy into microwave energy consumption, decrease in the energy consumption for a fixed output of the microwave power of the klystron and an increase in the efficiency of transit klystrons.
