Future fusion reactors should be operated at the highest possible plasma density. However, the maximum achievable density is limited by turbulent processes. [more]
After first measurements with the new Thomson scattering diagnostics in the divertor (Divertor-TS), the spectral channels for the analysis of the photon spectra and the laser beam guidance in the vacuum vessel of ASDEX Upgrade were optimized. [more]
With the thermal helium beam diagnostics the dynamics of plasma edge fluctuations can be observed from the confined region up to the far scrape-off layer. [more]
