Xenonplasma

Xenonplasma refers to a plasma in which xenon is the dominant constituent. It forms when xenon gas is ionized by electric discharge, intense laser pulses, or other energy sources. The plasma contains xenon ions in various charge states and free electrons, and it emits spectral lines from xenon transitions, producing a bright glow. Xenon, a heavy noble gas, leads to high radiative efficiency and strong line emission compared with lighter plasmas.

Production and properties: Xenonplasma is produced in xenon arc lamps, high-intensity discharge lamps, and laboratory plasmas created by pulsed power, RF, or lasers. Ionization yields Xe+, Xe2+, Xe3+ and higher, depending on temperature and density. Temperatures range from thousands to tens of thousands of kelvin, with varying densities. The plasma can be optically thick, and radiation influences energy balance and cooling.

Applications and research: Xenon plasmas are used in lighting and display technology for bright emission and short pulses. They serve as propellants in ion engines and Hall-effect thrusters, where ionized xenon is accelerated to produce thrust. In plasma physics and spectroscopy, xenon plasmas provide a rich set of emission lines for diagnostic work.

Terminology: Xenonplasma is not a standardized category but a descriptive term for xenon-dominated plasmas. Properties depend on energy source, pressure, and gas admixtures. Safety follows standard noble-gas and high-energy-plasma precautions, noting hot temperatures and radiation hazards.
