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 ...

IEEE Transactions on Plasma Science, 1991
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 ...

Microinstabilities in the plasma focus
Physics Letters A, 1977Abstract Experimentally observed suprathermal microwave emission correlated to soft X-rays emitted with high anisotropy are indicating the existence of current driven microinstabilities in the plasma focus.

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 ...

Computational simulation of plasma focus
AIP Conference Proceedings, 2001The movement and shaping of the plasma sheet in a plasma focus is modeled by means of finite elements. The sheet is represented by conical segments carrying mass, internal energy and momentum. The Lorentz force accelerates each element in its normal direction, which leads to the continuous reshaping of the sheet.

Generation of compact plasma objects in plasma focus discharge
EPL (Europhysics Letters), 2020This paper provides the results of studies of plasma flows generated in the plasma focus facility PF-1000U. Regimes are found, involving the formation of compact plasma objects propagating in the variable-density background environment to the distances exceeding the initial crosswise dimensions of these objects by dozens of times.

Comparison of plasma focus calculations
The Physics of Fluids, 1982A simple model for the current history of plasma focus experiments is presented. The presence of a leak current which does not pass through the plasma sheath is allowed. Results are found to compare quite well with those of much more sophisticated two-dimensional magnetohydrodynamic calculations.

Types of fresh plasma with focus on therapeutic plasma exchange
Transfusion and Apheresis Science, 2019Among blood components for transfusion, plasma for direct therapeutic use is one which has the most diverse presentations as it can either be a labile (fresh) component or a drug when industrially manufactured after pooling of thousands of individual plasma collections.

Publisher Summary This chapter describes the dense plasma focus. Dense plasma focus (DPF) is a plasma discharge with plasma densities n > l0 l9 /cm 3 and temperatures of a few kilo electron volts lasting 100 to 150 nsec. The focus is conjectured to be a short but finite two-dimensional z -pinch forming near or at the end of a coaxial plasma ...
