Plasma focus devices

Physica B+C, 1976
Abstract Plasma focus devices are presently investigated in about 20 laboratories. All these devices generate hot (some 100 eV-some keV), dense (10 17 −10 20 particles cm −3 ) and short-lived (5−200 ns) plasmas. Due to improved diagnostics and theoretical models considerable progress in the understanding of these devices has been made since their ...

Unconventional plasma focus devices

IEEE Transactions on Plasma Science, 2006
The 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.

Formation of the plasma layer in a plasma focus device

Physics Letters A, 1980
Abstract Optical and probe measurements show the formation of a double layer produced by a discharge along the insulator and radial filamentary discharges.

The initial phase in plasma focus devices

Plasma Physics and Controlled Fusion, 1993
A discussion of the initial phase in plasma focus devices is given, in the light of the available experimental and theoretical knowledge on this subject. The influence of this phase on the focus phase is also discussed.

Structure of plasma sheath in a plasma focus device

1990 Plasma Science IEEE Conference Record - Abstracts, 1990
Summary 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.

Beam acceleration in plasma focus device

Radiation Measurements, 2001
The proton beam emission from the small 8 kJ plasma focus device operated with the H2 4lling was analyzed. Maximum energy and yield were obtained using NTD. The fast protons were registered with the energy up to 500 keV using the polycarbonate absorbers with the di9erent thickness. c 2001 Elsevier Science Ltd. All rights reserved.

Magnetohydrodynamic simulation for plasma focus devices

Plasma Devices and Operations, 2007
To overcome the discontinuity between the axial phase and the radial phase in the plasma focus, a new model (the Masoud model) has been developed. It is assumed that, according to the snowplough model, the radial phase moves in the angular direction with continuity between the axial and the radial phases.

A scaling law for plasma focus devices

Physics Letters A, 1981
Abstract The neutron yield N in plasma focus devices is scalable with the sheet current I s according to N ∼ I 3.2 s . The efficiency of the current transfer into the sheet can be computed by means of a scaling law based on a simple fluid model.
