Abstract
The Gamma–4 four-module electrophysical facility has been designed for generation of powerful bremsstrahlung radiation pulses. One of the basic modes of operation of the facility is the operation of each module with its autonomous vacuum diode. The electrical characteristics of the high-current self-magnetic pinch diode of the typical module of the Gamma–4 facility (the Gamma–1 pulsed electron accelerator) are determined. It is shown that by changing the diode impedance in the range 1.3–4.0 Ω, it is possible to implement operation modes in which bremsstrahlung radiation pulse with a limiting quantum energy of 0.9 to 2.0 MeV are formed.
