of the dense plasma focus for short-pulse applications
plasma focus (DPF) has long been considered a compact source for pulsed
neutrons and has traditionally been optimized for the total neutron yield. In
this paper, we describe the efforts to optimize the DPF for short-pulse
applications by introducing a reentrant cathode at the end of the coaxial
plasma gun. The resulting neutron pulse widths are reduced by an average of
21±9% from the traditional long-drift DPF design. Pulse widths and yields
achieved from deuterium-tritium fusion at 2 MA are 61.8±30.7 ns FWHM and
1.84±0.49×1012 neutrons per shot.
