ELECTRON MINIACCELERATOR ON THE BASE OF TESLA TRANSFORMER FOR THE BEAM OF CHARGED PARTICLES NONDESTRUCTIVE TESTINGS

The electron miniaccelerator on the base of Tesla transformer for the beam of charged particles nondestructive testing with operating voltage up to 200 kV, half-wave duration 4 mks and diagnostic beam current within few mA is described. The primary circuit is switched by IGBT-module. The gun control and filament circuit power supply (impregnated cathode with 1.2 mm diameter) are performed through high frequency isolated transformer. The accelerating tube is performed f rom sectional welded metal ceramics insulator (ceramics 22HS with diameter 95/85 mm). The accelerators test results are presented.
