Predictions of Bremsstrahlung Dose Output of “Gamma-4” Facility

The object under study is electrophysical facility “Gamma-4” aimed at generation of bremsstrahlung pulses with duration of ~50 ns. The results of calculations of spatial distribution of absorbed dose in the near-field are presented. The calculations have been made for two operating modes of the facility - fully electrically independent modules with separate vacuum diodes, and modules connected to the common vacuum diode load. The calculations have been performed with the aid of Monte-Carlo code S-007 made in RFNC-VNIIEF.
