Abstract
Time-resolved flux distribution has been measured with a rotatable col lector probe in an ohmically heated divertor discharge of deuterium. T he transient flux at the beginning of the discharge is found to affect largely the time-integrated flux distribution in the whole SOL. Withi n a middle part of the SOL region the spatial flux distribution of deu terium is found to have two exponentially decreasing components, due t o a shielding effect of a fixed limiter.
