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.
Plasma lamps are a type of electrodeless gas-discharge lamp energized by radio frequency (RF) power. They are distinct from the novelty plasma lamps that were popular in the 1980s. The internal-electrodeless lamp was invented by Nikola Tesla after his experimentation with high-frequency currents in evacuated glass tubes for the purposes of ...
A glow discharge is a plasma formed by the passage of electric current through a gas. It is often created by applying a voltage between two electrodes in a glass tube containing a low-pressure gas. When the voltage exceeds a value called the striking voltage , the gas ionization becomes self-sustaining, and the tube glows with a colored light.
A deuterium arc lamp (or simply deuterium lamp) is a low-pressure gas-discharge light source often used in spectroscopy when a continuous spectrum in the ultraviolet region is needed. Plasma "arc" or discharge lamps using hydrogen are notable for their high output in the ultraviolet, with comparatively little output in the visible and infrared.
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.

This work and later experiments using mammalian cells led to the establishment of a new field of research known as plasma medicine. The dielectric barrier discharge configuration was also used in the design of low temperature plasma jets. These plasma jets are produced by fast propagating guided ionization waves known as plasma bullets. [64]
The plasma itself is used to modify or clean (plasma cleaning) surfaces of materials (e.g. polymers, semiconductor surfaces), that can also act as dielectric barrier, or to modify gases [19] applied further to "soft" plasma cleaning and increasing adhesion of surfaces prepared for coating or gluing (flat panel display technologies).
