  2. Direct-current plasma - Wikipedia

    en.wikipedia.org/wiki/Direct-current_plasma

    Direct-current plasma (DCP) is a type of plasma source used for atomic emission spectroscopy that utilizes three electrodes to produce a plasma stream. [1] The most common three-electrode DCP apparatus consists of two graphite anode blocks and a tungsten cathode block arranged in an inverted-Y arrangement.

  3. Plasma (physics) - Wikipedia

    The plasma approximation: The plasma approximation applies when the plasma parameter Λ, [26] representing the number of charge carriers within the Debye sphere is much higher than unity. [ 19 ] [ 20 ] It can be readily shown that this criterion is equivalent to smallness of the ratio of the plasma electrostatic and thermal energy densities.

    Plasma is the fourth state of matter. Atoms and normal matter have a nucleus with orbiting electrons. In plasma, the atoms have been torn apart and the electrons ripped away.

    The various modes can also be classified according to whether they propagate in an unmagnetized plasma or parallel, perpendicular, or oblique to the stationary magnetic field. Finally, for perpendicular electromagnetic electron waves, the perturbed electric field can be parallel or perpendicular to the stationary magnetic field.

  6. Non-neutral plasma - Wikipedia

    en.wikipedia.org/wiki/Non-neutral_plasma

    In physics a non-neutral plasma is a plasma whose net charge creates an electric field large enough to play an important or even dominant role in the plasma dynamics. [1] The simplest non-neutral plasmas are plasmas consisting of a single charge species.

  8. Plasma modeling - Wikipedia

    en.wikipedia.org/wiki/Plasma_modeling

    Plasma modeling refers to solving equations of motion that describe the state of a plasma. It is generally coupled with Maxwell's equations for electromagnetic fields or Poisson's equation for electrostatic fields. There are several main types of plasma models: single particle, kinetic, fluid, hybrid kinetic/fluid, gyrokinetic and as system of ...

  9. Category:Plasma types - Wikipedia

    en.wikipedia.org/wiki/Category:Plasma_types

    This is a loosely defined category listing types of plasma named by a prominent characteristic, such as the location (e.g., astrophysical plasma), a property (e.g., nonthermal plasma), mode of its generation (e.g., induction plasma), etc.
