Electron beam injector

The principle of electric field production in an accelerating gap of an injector is based on induction method. Such an approach permits obtaining small weight and size of the injector at maximum use of an operating volume. Ferromagnetic system, pulse generator, multichannel spark gap, cathode and anode units are the main elements of injector lay-out diagram. The injector is based on the ferromagnetic system comprising twelve toroidal cores with one-coil winding separated by ring fibreglass insulators. Electron beam peak energy is obtained at injector voltage of 700 kV. Beam total current is 6.5 kA at 40 ns FWHM pulse duration, pulse repetition frequency being 1-10 pulse per s.
