Paper Abstract

Asdex Upgrade (AUG) is a toroidal magnetic plasma confinement experiment for nuclear fusion research. It is of the tokamak type, having maximum values for toroidal plasma current and magnetic field of 2 MA and 3.9 T respectively. The experiment will go into operation this year. Measurement of electron temperature and density are of extreme importance for the understanding of basic plasma phenomena. One of the most unambiguous measuring methods is Thomson scattering with pulsed high power lasers as a light source. The scattering system for AUG described here is an improved version of the existing device on ASDEX. Special emphasis has been put on wide flexibility to match different discharge conditions, and operating reliability combined with high total optical transmission and spacial and temporal resolution without losing the capability of recording the long term development of plasma parameters during a discharge.
