VACUUM DIODE ASSEMBLY OF HIGH-CURRENT ELECTRON ACCELERATOR WITH DOUBLE CATHODE AND MECHANISM OF RAPID CHANGE OF OPERATING CURRENT Russian patent published in 2016 - IPC H05H5/00 

FIELD: physics.

SUBSTANCE: invention relates to accelerators and can be used in making high-current pulsed electron accelerators, in particular, vacuum diode assemblies of high-current electron accelerator with double cathode and mechanism of rapid change of operating current. Device comprises vacuum housing with anode diaphragm and cathode holder, wherein before anode diaphragm fixed cathode made in form of working and ballast cathodes installed on movable piston, as well as hydraulic transmission containing driving mechanism installed outside vacuum housing, dielectric tube installed in vacuum housing and connected with master inlet end of mechanism to feed hydraulic transmission working fluid into it, and flexible hose. Movable piston is equipped with hydraulic transmission actuator, outlet end of dielectric tube is fixed in cathode holder housing, flexible hose is installed between output end of dielectric tube coated with layer of electrically conducting material, and hydraulic transmission actuator with possibility to transfer working fluid into it presented by conductive liquid. At dielectric tube and hose connection point ohmic contact of electrically conducting liquid with high-voltage cathode holder housing is provided, and at dielectric tube with grounded vacuum housing connection point ohmic contact is provided by electrically conducting liquid with vacuum housing.

EFFECT: high reliability.
