Plasma motion and neutron emission in an 18-kJ plasma focus
Abstract
Investigations at the DPF-40 Mather-type plasma focus (20 kV, 18kJ) show that the anode end structures notably influence the neutron yield via plasma motion. The hollow anode forms an uniform plasma pinch in a pure magnetically confined state. The plasma motion is more reproducible with a hollow anode structure and produces a neutron yield of Yn = (2.2 ± 0.5) × 10 8 per shot, {ΔY n}/{Y n} =±23% , which is more suitable for the plasma focus neutron source and for plasma fusion/physics research.
