Unconventional plasma focus devices
IEEE Transactions on Plasma Science, 2006The Plasma Focus (PF) characteristics have been investigated in the Two-Guns configuration (TWIN) with a 10-kJ class device. Electrodes with two different heads shapes, hollow (GYN) or hemispherical (PHAL), have been tested and the results show that the neutron yield is greater in the GYN configuration.

The heating of plasma focus electrodes
Plasma Sources Science and Technology, 2006Plasma focus (PF) technology development today is strictly related to the possibility of a high frequency repetitive working regime. One of the more relevant obstacles to this goal is the heating of structural components due to direct interaction with plasma.

Low voltage operation of plasma focus
Review of Scientific Instruments, 2010Plasma foci of compact sizes and operating with low energies (from tens of joules to few hundred joules) have found application in recent years and have attracted plasma-physics scientists and engineers for research in this direction. We are presenting a low energy and miniature plasma focus which operates from a capacitor bank of 8.4 μF capacity ...

It is possible to breed fissile fuels with the help of a high current plasma focus device instead of using linear accelerators. A mechanism for accelerating a proton beam in a plasma focus device to a high energy would be the change of inductance in the plasma column caused by a rapid growth of plasma instability.

Interferometry of plasma focus discharge
2009 IEEE International Conference on Plasma Science - Abstracts, 2009Summary form only given. The plasma focus facilities are simple and effective sources of fast ions. At the usage of deuterium gas the fusion neurons from fusion D-D reactions are produced. The plasma produced in plasma focus facilities is convenient for interferometry diagnostics with impulse laser beam in visible wave range.

Effect of plasma sheath structure in plasma focus
IEEE Transactions on Plasma Science, 1993The development of plasma sheath in the run-down phase and pinch phase in a plasma focus is studied with laser interferometry. The time-resolved interferograms show that the structures of plasma sheaths in the run-down phase are different at low and high pressures of filling gas. This leads to a distinct plasma pattern above the anode.

In the article “Fusion plan gathers steam” describing the U.S. House of Representatives Energy and Environment Subcommittee hearing on restructuring the fusion energy program ([22 Mar., p. 1660][1]), Andrew Lawler quotes me as “warn[ing] that the lack of small-scale university fusion experiments is keeping young people from entering the field.” While ...

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 ...

Shadowgraph studies suggest that a target disk placed downstream of the anode of a plasma focus may become an auxiliary anode producing a second focusing event when the current sheet climbs over it after the first focus event. A model is put forth in which each event is assumed to comprise three phases: an axial phase, a radial phase, and a radial ...
