Plasma interactions as a research area investigates the fundamental processes governing how plasmas interact with fields, particles, and material boundaries in laboratory, space, and astrophysical environments. It encompasses collisional and collisionless regimes, wave–particle and wave–wave interactions, magnetic reconnection, sheath formation at surfaces, and energy and momentum transfer between charged and neutral species. This field integrates kinetic and fluid (MHD, two-fluid, gyrokinetic) descriptions, advanced diagnostics, and numerical simulations to study phenomena such as turbulence, transport, instabilities, and nonlinear structure formation, with implications for fusion devices, space weather, propulsion, and high-energy-density plasma systems.
Fusion researchers are increasingly turning to the element tungsten when looking for an ideal material for components that will directly face the plasma inside fusion reactors known as tokamaks and stellarators. But under ...
