Laser-induced fluorescence of metal-atom impurities in a neutral beam
Abstract
The need to limit impurities in fusion devices to low levels is well known. By the technique of laser-induced fluorescence, the concentration of heavy-metal atoms in a neutral beam caused by their evaporation from the hot filaments in a conventional high-current multifilament hydrogen-ion source was investigated.
