ELECTRON BUNCH GROUPING DEVICE Russian patent published in 1996 - IPC

FIELD: microwave engineering. SUBSTANCE: electron bunch grouping device has input electrodynamic system and n electrodynamic system of grouping amplifier arranged in tandem along device axis, where n is greater than 3, each system incorporating at least one active cavity distinguished by that its input electrodynamic system is tuned to extreme low frequency or working frequency band accurate to value chosen from condition given in description of invention. EFFECT: provision for preventing formation of electron bunch and its group separation within working frequency band; reduced dependence of amplitude-frequency response of entire device on tuning frequency of each intermediate electrodynamic system. 4 cl, 1 dwg
