Plasma detachment in tokamaks is useful for reducing heat flux to the target. It involves interactions of the plasma with impurities and
neutral particles, leading to significant losses of plasma power, momentum, and particles. Accurate mapping of plasma emissivity
in the divertor and X-point region is essential for assessing the relationship bet…
During detachment, a buffer of neutral atoms and molecules builds up between the target and the ionising plasma. Collisions between the plasma and the molecules play an important role in the detachment process. Studies of plasma-molecular kinetics indicate that the gas temperature is increased during detachment for a wide range of conditions on the…
