Fusion plasmas

Within Association EURATOM-ÖAW we develop:

• Fusion plasma diagnostics: Based on the injection of fast neutral Li - and He-beams, to measure spacial and temporally resolved profiles of electron and ion densities as well as temperatures. Diagnostic experiments are conducted at large (JET) and medium size (ASDEX-upgrade) tokamaks and stellerators (WENDELSTEIN 7-AS). The interaction of the injected beam with the plasma is modeled using collisional-radiative codes. To this purpose atomic collision data for the relevant reactions are collected and evaluated.

• Plasma-wall interaction

• Atomic data for fusion ADAS-EU

In addition we construct and build our own ion sources to produce beams of highly charged ions for our collision experiments:

• ECR ion source development: An all-permananet magnet 14.5 GHz Electron Cyclotron Resonance (ECR) ion sources (SOPHIE) has been built and is used for production of highly charged ion beams.
