Experimental device and experiments on the electron beam acceleration in the radial line system

Experimental device for electron beam acceleration in the system of three double radial lines (DRL) with ferrite, excited by an external pulse generator, is described. Results of experiments on acceleration of the beam with 100 A order current, obtained with the help of explosive cathode, positioned in accelerating field of the first DRL, are analyzed. Energy of accelerated electrons equal to 200 keV is obtained at the voltage pulse amplitude in transmitting cables equal to 22 kV, that corresponds to the accelerating field voltage of about 20 kV/cm. It is shown experimentally that the given method permits to obtain the accelerating voltage which several times exceeds the feeding voltage
