Plasma acceleration — is a technique for accelerating charged particles, such as electrons, positrons and ions, using an electric field associated with an electron plasma wave. The wave is created by the passage of a very brief laser or electron pulse through the… … Wikipedia
Plasma parameters — define various characteristics of a plasma, an electrically conductive collection of charged particles that responds collectively to electromagnetic forces. Plasma typically takes the form of neutral gas like clouds or charged ion beams, but may… … Wikipedia
Plasma stealth — is a proposed process that uses ionized gas (plasma) to reduce the radar cross section (RCS) of an aircraft. Interactions between electromagnetic radiation and ionized gas have been extensively studied for a variety of purposes, including the… … Wikipedia
Plasma diagnostics — are experimental techniques used to measure properties of a plasma such as temperature and density. Langmuir probe Measurements with electric probes, called Langmuir probes, are the oldest and most often used procedures for low temperature… … Wikipedia
Plasma oscillation — Plasma oscillations, also known as Langmuir waves (after Irving Langmuir), are rapid oscillations of the electron density in conducting media such as plasmas or metals. The frequency only depends weakly on the wavelength. The quasiparticle… … Wikipedia
Plasma lamp — Plasma lamps (also variously plasma globes, balls, domes, spheres, or orbs) are novelty items which were most popular in the 1980s. The plasma lamp was invented by Nikola Tesla after his experimentation with high frequency currents in an… … Wikipedia
Plasma Contactor — Plasma contactors are devices used on spacecraft in order to prevent accumulation of electrostatic charge through the expulsion of plasma (often Xenon).An electrical contactor is an electrically controlled switch which closes a power or high… … Wikipedia
Plasma source — Plasma sources generate plasmas. Excitation of a plasma requires partial ionization of neutral atoms and/or molecules of a medium. There are several ways to cause ionization:collisions of energetic particles, strong electric fields acting on bond … Wikipedia
