Beam-Plasma Heating Model

IEEE Transactions on Plasma Science, 1979
A one-dimensional ionization and heating model is applied to results of several electron-beam-plasma interaction experiments. Beam energy is deposited resistively in the plasma at a rate ?j2, where j is the return current density and ? the plasma resistivity both classical and anomalous due to ion acoustic or e-e-mode turbulence.

I.3.1. Plasma heating

Journal of Fusion Energy, 1983
Typical neutral-beam injectors for present-day physics experiments are turning to a commercial base and users. The machine parameters of the typical NBI are an acceleration voltage of 20 to 40 kV and a maximum output of 1 MW per beam line with a pulse duration of about 100 ms.

Antiprotons for plasma heating

Hyperfine Interactions, 1997
The design of the new Antiproton Decelerator (AD) at CERN will allow the easy measurement of the energy deposit of the antiproton-proton annihilation remnants within a hydrogen plasma. For this purpose, a reaction chamber filled with gaseous hydrogen is put into the beam line.

Plasma Heating with Electrically Biased Plasma Guns

Transactions of the Kansas Academy of Science (1903-), 1994
Electrically biased plasma guns firing across the magnetic field are an effective way to heat a magnetically confined plasma. INTRODUCTION AND THEORY It is well established that intense plasma beams can propagate across a magnetic field and refuel a plasma in a closed magnetic trap (Robertson et al., 1981; Demidenko et al., 1971; Demidenko, Lomino, and

Turbulent Plasma Heating.

1979
Abstract : This research involved measurements of plasma heating using electron beams, anomalous dc resistivity, and double layers. In addition, the development of a compact x-ray source is being investigated. An extensive set of measurements of the interactions of an electron beam with a collisionless plasma is summarized.

Plasma Wall Interactions in Heated Plasmas

1986
With the development of larger, more powerful magnetic confinement devices, the study of plasma-wall interactions becomes increasingly relevant to the controlled thermonuclear fusion program. To increase the plasma temperature in Tokamaks from the value reached by ohmic heating (1 – 2 keV), toward the value necessary for self sustaining fusion ...

Plasma actuated heat transfer

Applied Physics Letters, 2008
We introduce plasmas for film cooling enhancement in gas turbines and other engineering applications. We identify mechanisms to actuate essentially stagnant fluid just downstream of the cooling hole by employing three-dimensional body force for different hole geometries.

Nanophotonics for plasma heating

Nature Photonics, 2013
Vertically aligned nanowires on a solid surface in conjunction with table-top lasers create an ultrahigh-energy-density plasma with extremely high ionization in the laboratory.

Semicollisional heat flux in laser heated plasmas

Physics of Plasmas, 2002
The semicollisional transport theory in laser heated plasmas is presented. The Fokker–Planck equation that includes the electron–electron interaction up to the first anisotropy is solved numerically for arbitrary collisionality range. The inverse bremsstrahlung absorption of the laser energy by the electrons is taken into account.
