The Dense Plasma Focus: A Versatile Dense Pinch for Diverse Applications
IEEE Transactions on Plasma Science, 2012The dense plasma focus (DPF) is a Z-pinch that has been studied for 50 years. Within ten years of its discovery by Fillipov and Fillipova in Russia and Mather in the USA, this dense pinch was scaled up to 2-MA currents and neutron outputs of ~ 1012/pulse.

Redirection of Current in a Dense Plasma Focus
The Mission Support & Test Services (MSTS) reports that significant amounts of energy needed for generating high energy neutrons is lost within a Dense Plasma Focus between its pinch-end of the anode stalk and at its base near the insulating sleeve. It is their mission and the goal of this research effort to both experimentally and theoretically study ...

Dynamics of a microscale dense plasma focus
2011 Abstracts IEEE International Conference on Plasma Science, 2011Experimental results are presented for a sub-millimeter dense plasma focus (DPF). Reducing the DPF from cm to µm sizes allows for unique applications such as portable neutron based detectors. With smaller size efficiency is expected to increase, but total neutron emission will be lower.

A pulse current generator for dense plasma focus
Journal of Instrumentation, 2021Abstract A pulse current generator applied in a type of high-yield intense pulsed neutron source, the Dense Plasma Focus (DPF), is designed and developed in this paper. There are three key components in this generator. Each group of capacitors and switches is integrative to meet the DPF's requirements of low circuit inductance.

Dense-plasma spheromak in plasma focus experiments
International Conference on Plasma Science (papers in summary form only received), 1995Summary form only given, as follows. Experimental evidence is presented for the formation, formerly predicted, of a closed, spheromak-like magnetic configuration (SLMC) by the plasma-focus-self-transformed magnetic field. The SLMC formation is characterized by (1) self-consistent generation of a poloidal magnetic field (the dynamo effect); (2) strong ...

Ion Heating in the Dense Plasma Focus
The Physics of Fluids, 1971The collapse phase of a dense plasma focus gun operating in deuterium was studied using streak photography and time resolved x-ray and neutron measuring techniques. The streak photographs, showing the radial motion of the luminous front at various axial positions, indicate a collapsing luminous front at the time of the current collapse followed by an ...

The nitriding of aluminium by dense plasma focus
Plasma Sources Science and Technology, 2006High current, short length nitrogen ion beam pulses emanating from a low energy (1.8 kJ) Mather type plasma focus device are utilized for room temperature surface nitriding of aluminium specimens. X-ray diffraction (XRD), scanning electron microscopy and microhardness are used to study the surfaces of untreated and treated specimens.
