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.

Radio Frequency Plasma in Water

Japanese Journal of Applied Physics, 2006
We generate a radio frequency (RF) plasma in water at an atmospheric pressure by applying an RF power of 13.56 MHz from an electrode. The plasma is in a bubble formed in water. On the basis of hydrogen spectral lines under the assumption of thermal equilibrium, the temperature of the plasma is estimated to be 4000–4500 K. Spectroscopic measurements

Inductive coupled radio frequency plasma bridge neutralizer

Review of Scientific Instruments, 2008
A 13.56MHz radio frequency plasma bridge neutralizer (rf-PBN) for ion thruster applications as well as ion beam surface processing of insulating materials is presented. The energy for the plasma excitation is inductively coupled into the plasma chamber.

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

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.

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.
