COLLECTOR FOR O-TYPE MICROWAVE VACUUM-TUBE DEVICE Russian patent published in 2014 - IPC H01J23/27 

FIELD: physics.

SUBSTANCE: invention relates to vacuum-tube devices, particularly to collectors in travelling-wave tubes, multiple-beam klystron and klystrons which employ recuperation of kinetic energy of electrons coming out the electrodynamic system of the device. The collector has a housing, an insulator, a device for generating a transverse electric field and electrodes, wherein the housing is equipped with a multi-pin leg in form of a ceramic disc, and the device for generating a transverse electric field is placed in front of the electrodes and is in form of coaxially arranged ring and cylindrical cup. The electrodes form a double-row multi-section system, each section having an external electrode and an internal electrode with flat end surfaces and cylindrical side surfaces. The collector is also provided with an additional electrode which is in form of a disc and is placed behind electrodes of the last section, external and internal additional insulators in form of a washer and placed on both sides of each internal and external electrode, dielectric tubes and conductors. All electrodes and insulators, as well as the multi-pin leg are arranged coaxially, and the sizes of the outer diameters of the external electrodes, external additional insulators, the ring and the additional electrode are identical, wherein the external cylindrical surfaces of the additional electrode and the ring are connected to the internal surface of the insulator, and the electrodes and additional insulators have openings which form cylindrical cavities in which the dielectric tubes are inserted, said tubes having conductors inside them, which connect the ring, the cylindrical cup and each of the electrodes with the corresponding pin of the multi-pin leg.

EFFECT: high efficiency and longer service life of the device.
