A plasma ball with filaments extending between the inner and outer spheres. A plasma ball, plasma globe, or plasma lamp is a clear glass container filled with noble gases, usually a mixture of neon, krypton, and xenon, that has a high-voltage electrode in the center of the container.
William P. Parker is an American artist, scientist, and entrepreneur, best known for inventing the modern design of the plasma globe. [1] The invention occurred in 1971, when Parker was working as a student in a physics laboratory at the Massachusetts Institute of Technology and accidentally filled a test chamber to a greater-than-usual pressure with ionized neon and argon.

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.
