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 ...

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.

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.

Structure of plasma sheath in a plasma focus device
1990 Plasma Science IEEE Conference Record - Abstracts, 1990Summary form only given. Experiments were conducted on a device consisting of a condenser bank with 81 mF at 20-30 kV. The propagation of the plasma sheath in the rundown phase and pinch phase was studied by laser interferometry. The di/dt signal and X-ray yield were measured at the same time.

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 ...

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.

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 ...

The name Plasma Focus (PF) has been bestowed upon a development of the fast dynamic Z-pinch characterized by a new type of electrode configuration which lends itself to the production of a non-cylindrical implosion of the current sheath. It produces a short lived, rather dense plasma, whose properties are dominated by the occurrence of macroscopic and ...

Electron kinematics in a plasma focus
The Physics of Fluids, 1977The results of numerical integrations of the three-dimensional relativistic equations of motion of electrons subject to given electric and magnetic fields are presented. Fields due to two different models are studied: (i) a circular distribution of current filaments, and (ii) a uniform current distribution; both the collapse and the current reduction ...
