Abstract

Detachment is required to mitigate the power exhaust of future fusion reactors. It is induced by a complex chain of plasma-atom and molecule interactions resulting in simultaneous power, particle and momentum losses. Dissecting these processes experimentally using plasma spectroscopy and novel analysis of the Balmer line series indicated that the reduction of divertor ion sources during detachment, brought on by power limitation, reduces the ion target flux initially. As detachment evolves, lower target temperatures are obtained, which lead to volumetric momentum losses, enhanced molecular densities that lead to molecularactivated recombination; and ultimately electron-ion recombination.
