The high frequency compact generator of accelerating voltage on 500 kV, 10kW

A cascade accelerating-voltage generator with inductive coupling and parallel power supply to the cascades is examined. The basic parameters and dimensions of a generator for a voltage of 500 kW and power 10 kW are presented. The generator is designed to power a tandem charged-particle accelerator. Energy-stabilized (to within ± 0.1 %) charged-particle beams are used to study the structure of nuclei (resonance interaction of γ-rays with nuclei) and for solving the problems of using fast neutrons for therapeutic purposes. The layout of the generator units is similar to that in the ELV accelerators [1]. The appearance of rf rectifier stacks (RHC manufactured by Electronic Devices Co., 2PF140 manufactured by Semtech Co., and KTs108V) and bipolar transistors with an insulated gate (IGBT) on the market has stimulated the development of an rf compact generator and switching the power supply frequency from 400 Hz to 20 kHz. The basic parameters of the accelerating-voltage generator are as follows: Maximum voltage, kV..........………..................................... 500 Power, kW............................................................................. 1
