High-current electron accelerator based on pulse generator with vacuum insulation

This report presents the description of the electron accelerator on basis of the powerful small-inductive pulse generator with vacuum insulation. Using of the generator with vacuum insulation allows to simplify considerably a design of the accelerator having excluded from it an intermediate store. The accelerator tests results and also the experimental results on obtaining of the large cross-section ribbon beams with the ~500-700 keV electron energy are reported. Distinctive feature of the accelerator configuration for the ribbon beam generation is the cathode arrangement in parallel to the generator column axis. It is shown that in such configuration it is possible to receive practically homogeneous ribbon beam with the current density of 25 A/cm² and the cross-section of 25×100 cm².
