Abstract

The application of large collection optics to image millimeter waves on a detector array improves the spatial resolution and enables the recovery of small-scale structures and fluctuation characteristics of the plasma electron temperature and density from radiometer and reflectometer measurements. Both diagnostic techniques are combined into a single instrument on the TEXTOR tokamak.
