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 5×10 10 . The maximum of the neutron production occurred up to 200 ns later than the maximum of the soft X-rays.
