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 ...
Ion beam measurements in a small plasma focus operating in hydrogen/gas mixtures
Dense transient plasmas of high energy density, can be easily produced in a plasma focus device, on a cost effective basis. High energy ion beam emission is one, among several others, of the very interesting transient ...
Time-Varying Inductance of the Plasma Sheet in the PF1000 Plasma-Focus Device
(Institute Of Electrical And Electronics Engineers, 2016-05)
The time-varying inductance Lp(t) of the system formed by the coaxial electrodes and the current sheet (CS) in plasma focus (PF) discharges was calculated for the first time by Mather and Bottoms  on a 13-kJ PF device ...
Dynamics and Density Measurements in a Small Plasma Focus of Tens-of-Joules-Emitting Neutrons
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2012)
MEASUREMENT OF PLASMA DENSITY IN A FAST AND COMPACT PLASMA FOCUS OPERATING AT HUNDREDS OF JOULES
(AMERICAN INSTITUTE OF PHYSICS, 2006)
It is known that there are plasma parameters that remain relatively constant for plasma focus facilities operating in a wide range of de energy, from 1kJ to 1MJ, such as: electron density, temperature and plasma energy ...
Experimental investigations of hotspots in a low energy plasma focus operating in hydrogen-argon mixtures
We present experimental results on the investigation of hotspot formation in PFP-I, a small 3.8 kJ plasma focus device operating in hydrogen-argon mixtures, at pressures from below 0.2 torr upward. A combination of ...
Radiographic method for measuring the continuum hard X-ray output spectrum of a Plasma Focus device
(Elsevier Science, 2009-12)
A radiographic method is proposed and then applied to infer the continuum part of the hard X-ray spectrum of a 4.7 kJ Plasma Focus from differential absorption measurements on metals. Copper, nickel, titanium and silver ...
Stray Capacitance in a Plasma Focus Device: Implications on the Current Derivative Calibration and the Effective Discharge Current
The notion that PF discharge circuits should be represented by an equivalent circuit having two loops instead of the traditional single one is presented. This implies that two frequencies must be expected in the currents ...
Correlations Among Neutron Yield and Dynamical Discharge Characteristics Obtained from Electrical Signals in a 400 J Plasma Focus
Dynamical discharge characteristics and their relation with the total neutron yield emitted from a 400 J plasma focus operating in deuterium gas are presented. The dynamical nature of the plasma focus is obtained ...
