A laboratory plasma is an ionized gas produced and confined under controlled experimental conditions to study fundamental plasma behavior and simulate space, astrophysical, or fusion-relevant environments. It is generated by applying electric fields, electromagnetic waves, lasers, or discharge currents to a neutral gas, creating a quasi-neutral mixture of ions, electrons, and neutrals characterized by collective interactions and long-range Coulomb forces. Laboratory plasmas span regimes from low-temperature, weakly ionized discharges to high-temperature, magnetically confined fusion plasmas, enabling investigation of transport, turbulence, wave–particle interactions, reconnection, and plasma–surface or plasma–material interactions under reproducible, diagnosable conditions.
Temperatures of more than 10,000°C and a hail of charged particles from the fusion fuel (plasma): These are extreme conditions that the exhaust wall (divertor) of future fusion power plants will need to withstand. It makes ...
