Wire-array implosion onto a deuterated fibre at the S-300 facility

Abstract

The implosion of a wire array z-pinch onto a deuterated fibre was studied on S-300 facility (4 MA, 700 kV and 100 ns; RRC Kurchatov Institute, Moscow). The peak power of soft X-rays exceeded 200 GW and the total emitted energy was 2–8 kJ. The radiation was close to the radiation of a black body with a temperature of 40 eV. The neutron yield from the D–D reaction reached 2 × 108 per shot. The mean energy of neutrons determined from time-of-flight analysis in the axial direction (downstream) was shifted from 2.45 MeV towards higher energies.
