Radio‐frequency plasma‐display cell

Journal of the Society for Information Display, 2003
Abstract— This paper demonstrates that it is possible to improve the basic parameters of plasma displays (efficiency, primarily) using AC voltages with frequencies so high that the amplitude of the electron‐drift oscillations is smaller than the inter‐electrode gap.

Plasma Paramagnetism in Radio-Frequency Fields

Physical Review Letters, 1979
A study by experiment, simulation, and theory has found that a plasma responds paramagnetically to the external rf magnetic field applied perpendicular to the static magnetic field with frequency $\ensuremath{\omega}l{\ensuremath{\omega}}_{m}$, ${\ensuremath{\omega}}_{m}$ being the Alfv\'en ion cyclotron frequency.

Radio-frequency heating of a plasma

Canadian Journal of Physics, 1970
If a uniform plasma is surrounded by a heating coil in the presence of a steady axial magnetic field, it is shown that a considerable increase in power absorption may be expected if the operating frequency is chosen to be close to a magneto-acoustic resonance of the plasma column. This effect is due to a very large increase in the oscillating field at

Radio-frequency fields in magnetoactive plasma

Journal of Applied Physics, 1974
Electric field componenets produced by a single-turn current sheet concentric with a finite magnetoactive plasma cylinder are calculated for frequencies corresponding to resonant peaks in the series loading resistance near the lower hybrid resonance. The radial electric fields are found to be quite large and to penetrate well into the plasma.

Laser Diagnostic of Radio-Frequency Oxygen Plasma

1990
We started the investigation of radio-frequency discharges of oxygen-noble mixtures because they are known to be efficient “generators” of atomic oxygen. In addition the discharge, in absence of chemical reactions at the electrodes, is particularly clean to allow high resolution laser spectroscopy investigations [1],[2],[3] which were our main purpose.

Radio-frequency coupling to plasmas

Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films, 1988
A survey of the physics associated with coupling rf power to plasmas is given with emphasis on methods of analysis relevant to applications in the fields of plasma production, processing, and fusion research. The significance of resonant versus nonresonant coupling methods is discussed and specific applications are described where these phenomena ...

Micro-arcing in radio frequency plasmas

Journal of Physics D: Applied Physics, 2004
Micro-arcing and breakdown of the wall plasma sheath in radio frequency (RF) plasmas is studied in a hollow cathode system, using a Langmuir probe to measure the floating potential. Micro-arcing was induced reproducibly by controlling the floating potential. By dc grounding the hollow cathode, a negative current can flow to ground resulting in a higher

Resonances of Radio Frequency Probe in a Plasma

Journal of the Physical Society of Japan, 1966
An RF probe experiment was carried out with a low density plasma, the resonances of the probe impedance were studied. The resonances were observed in a frequency range between the sheath-plasma resonance and the plasma frequencies. The mechanism of these additional resonances is discussed.

The Radio-Frequency Driven Plasma Sheath: Asymptotics and Analysis

SIAM Journal on Applied Mathematics, 2003
Summary: This paper considers the dynamics of a radio-frequency driven plasma consisting of ions and electrons. The method of matched asymptotic expansions is used to derive the dynamics in bulk quasi-neutral plasma, transition, and sheath regions. Furthermore, a constructive existence theorem is presented for solutions of the system governing sheath ...
