Correlation of X-ray emission with interferometry and neutron diagnostics at tungsten anode face and deuterium filling in plasma-focus discharge

Original language description

In this paper, the influence of the tungsten evaporated from the anode on neutron production and soft X-ray radiation was studied on the base of X-ray, interferometry and neutron diagnostics performed on the plasma focus PF-1000 device with deuterium asthe filling gas at the current of 2 MA and neutron yield above 1010. In the axial center of the anode face the copper circuit plate was substituted with a tungsten one. During the pinch, the tungsten ions evaporated from the anode were transported into the plasma column. The differences in the filters used in the MCP X-frames and PIN detectors enabled separation of the bremsstrahlung emitted by the deuterium plasma from the recombination radiation of the tungsten ions produced in the region of the plasma column near the anode at the time of the evolution of instabilities. In comparison with the copper anode face, the neutron yield decreased to 40 % and the energy of deuterons producing neutrons to 80%.
