Operation of a plasma-focus device with D2 and He3

Journal of Applied Physics, 1977
Two plasma-focus devices at the Lawrence Livermore Laboratory, the B Division device (BDPF), with a stored energy of 73 kJ at 18 kV, and the Physics Department device (PDPF), with a stored energy of 67 kJ at 20 kV, were operated with various mixtures of D2 and He3. The purpose of the experiments was to evaluate the D-D/D-He3 yield ratio as a diagnostic

The three-phase theory for plasma focus devices

IEEE Transactions on Plasma Science, 1997
A simplified theory for preliminary design of plasma focus devices that starts at the breakdown phase is proposed. For best focus, it is shown that the model can be used to predict the values of the inner and outer electrode radius, inner electrode length, gas pressure, and charging voltage that give minimum possible pinch radius.

Instability of the current sheath in plasma focus devices

Physics Letters A, 1984
Abstract We suggest a possible explanation to account for the previously observed existence of pressure dependent regimes during the implosion phase of plasma focus devices, in terms of viscous dominated Rayleigh-Taylor instabilities.

Plasma heating and emission of runaway charged particles in a plasma focus device

EPL (Europhysics Letters), 2016
The required experimental E-field across plasma to generate significant runaway electrons and hard X-rays during the pinch phase and the phase with anomalous resistance has been investigated in a dense plasma focus. The plasma voltage and inductance have been measured in a plasma focus with two different anode tip structures.

Production of radioisotopes with a Plasma Focus device

2005
In recent years, research conducted in the US and in Italy has demon strated production of radioiso topes in plasma focus de vices, and particularly, on what could be termed “endogenous” production, to wit, production within the plasma it self, as opposed to irradiation of tar gets.

Compression of puffing deuterium by neon plasma sheath on plasma focus device

2014 IEEE 41st International Conference on Plasma Sciences (ICOPS) held with 2014 IEEE International Conference on High-Power Particle Beams (BEAMS), 2014
The experimental research of fusion DD reaction was provided on the plasma focus device at the current of 2 MA in the approach with the MagLIF conception. The deuterium injected from the gas-puff in the axis of the anode and compressed by neon plasma sheath was studied with the multiframe x-ray and interferometry diagnostics. The total neutron yield at

Final stages of the plasma column evolution in the plasma-focus PF1000 device

IEEE Transactions on Plasma Science, 2002
A frame high-speed camera was used to visualize the evolution of the final stages of the plasma-focus phenomenon. The frame images were taken with a 1-ns exposure time in visible continuum radiation with a narrow band interference filter. These features of the diagnostic equipment enabled the detailed study of the collapse phase as well as the plasma ...

Preliminary results on the production of short-lived radioisotopes with a Plasma Focus device

Applied Radiation and Isotopes, 2005
An experimental campaign was conducted to assess the feasibility of short-lived radioisotope (SLR) production within the pulsed discharges of a Plasma Focus (PF) device. This so-called "endogenous production" technique rests on the exploitation of nuclear reactions for the creation of SLR directly within the plasma, rather than on irradiating an ...

Computer simulation of energy profiles in a plasma focus device

International Conference on Plasma Sciences (ICOPS), 1993
Summary form only given, as follows. The study of the plasma focus dynamics has been treated to include the distribution profiles of kinetic energy, electrical energy and the power input in the axial and the pinch off phase. The snowplow model equations and the pinch phase equations for plasma motion in one dimension and the equation of energies have ...
