Abstract

This report describes the hardware and software components of the ASDEX-Upgrade multichord visible spectroscopy system. The main emphasis is on a detailed description of the detector, a free programmable charge-coupled device intensified by a microchannel plate. As an experimental application, flux measurements of different impurity species from the inner heat shield are presented. Poloidal profiles of the released impurity amount obtained for various experimental situations are used to check the plasma position which is derived by the function parametrisation analysis.
