The μ-APPJ is a well-investigated atmospheric pressure RF plasma jet. Up to now, it has mainly been operated using helium as feed gas due to stability restrictions. However, the COST-Jet design including precise electrical probes now offers the stability

Plasma heat pump and heat engine
Physics of Plasmas, 2010A model system where cold charged particles are locally confined in a volume VP within a warm plasma of volume V (VP⪡V) is studied. Charged particles mutually repel via a shielded repulsion which is like an effective pressure, i.e., electrostatic pressure PE. The law of thermodynamics involving PE and an equation of state for PE are obtained.

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.

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, 1997The 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-), 1994Electrically 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

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
1986With 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 ...

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.
