Emission produced at compression of deuterium current-sheath with wire in plasma focus discharge

The implosion of a deuterium plasma toward an Al wire was performed at the current amplitudes of 1.5–1.8 MA. The Al wire of 120 µm diameter and 4–5 cm length was placed on the top of the inner electrode. Pulses of XUV radiation and soft X-rays were detected at the maximum compression of the plasma focus column. They contained lines of Al VI - Al Xm ions. The presence of the Al wire on the axis of plasma focus column caused a decrease in the hard X-ray production and neutron yield to about 30–50%. The neutron pulse was characterized by the FWHM ≈ 200 ns and the yield up to 5×10¹⁰. The maximum of the neutron production occurred up to 200 ns later than the maximum of the soft X-rays.
