Abstract

A combined visible and vacuum ultraviolet (VUV) scanning spectrometerfor the investigation of the boundary layer of ASDEX Upgrade has beendeveloped. A rotating mirror is used for poloidal scanning. This mirror can be tilted perpendicular to its rotation axis, enabling observation in the toroidal direction too. The broad spectral range opens a variety of investigation possibilities. Here we present poloidal radiation profiles of different ion species in the VUV. Regions of special interest such as the divertor for target erosion studies and the upper boundary for the estimation of ion penetration depths were investigatedwith high spatial resolution. Additionally, the application of this instrument is shown for measuring the spatial distributions of impurities injected for radiation cooling. (C) 1997 Elsevier Science S.A.
