Modeling of the Dynamic Plasma Pinch in Plasma Focus Discharges Based in Von Karman Approximations
(Institute of Electrical and Electronics Engineers, 2009-10-08)
Dynamic plasma pinches occur in a variety of devices, as Z-pinches and plasma focus. In this paper, a lumped parameter model of a dynamic plasma pinch produced in a plasma focus discharge is presented. The model is based ...
A model of hard X-rays emission from free expanding Plasma-Focus discharges
(IOP Publishing, 2014-05)
A planar-piston model of the hard x-ray production in Plasma-Focus devices is presented. The model applies Von Karman approximations to represent the inner structure of the pinch. The hard x-ray emission is calculated ...
Comment on Experimental evidence of thermonuclear neutrons in a modified plasma focus [Appl. Phys. Lett. 98, 071501 (2011)]
(American Institute of Physics, 2012-01)
On page 3 of Ref. 1, the authors claim: “It is for the first time when the ion temperature of thermonuclear Z-pinch plasmas is calculated from the width of neutron energy spectrum.” They are probably unaware of Ref. 2, in ...
Small Plasma Focus Studied as a Source of Hard X-ray
(Institute of Electrical and Electronics Engineers, 2001-06)
An experimental study on hard X-ray pulses emitted by a small plasma focus is performed, regarding its application to biological radiographs in fast dynamic situations. It is found that the radiation intensity in a single ...
A study of the effects of the cathode configuration on the plasma kinetics and neutron emission of plasma-focus discharges in deuterium
(IOP Publishing, 2020-05)
The differences in performance of a 1.9 kJ plasma-focus device PACO assembled with three different cathode configurations are experimentally qualified. In particular, the current sheath kinetics and the neutron yield ...
Physical Reasoning to Synchronize Electrical Signals and Related Diagnostics in Plasma Focus Devices
(Springer, 2018-02)
Plasma Focus (PF) devices as well as other similar pulsed discharge devices requires a variety of diagnostics for their proper control and optimization, including the voltage between electrodes, the time derivative of the ...
Conceptual Engineering of Plasma-Focus Thermonuclear Pulsors
(Institute of Electrical and Electronics Engineers, 2000-08)
A new method of significant efficiency enhancement, which is based on simultaneous interaction of electrons with an opposite wave at the second cyclotron harmonic, and a forward wave of the same frequency, at the fundamental ...
Evidences of Thermal and Non-Thermal Mechanisms coexisting in a Dense Plasma Focus D-D nuclear reactions
(IOP Publishing, 2000-01)
Dense plasma foci are the most efficient devices in the production of fast neutrons proceeding from deuterium nuclear fusion reactions. This work deals with experiments in a small plasma focus machine and attempts to ...
