Abstract

Toroidal visible array to measure toroidal distribution of H-alpha and He-I, ratio of helium to hydrogen: H/(H+He) or D/(D+He), and particle recycling and edge tau_p. H-alpha and He-I line emissions are detected by photomultipliers passing through an interference filter. H/D influx ratio can be also minitored by resolving H-alpha and D-alpha line profiles.
