Research activities:
Recent studies in the field of thermonuclear fusion based on magnetic confinement of high temperature plasma have demonstrated that the conditions at the plasma periphery ('plasma edge') play an important role for achieving, sustaining and controlling thermonuclear fusion. In order to understand and elucidate the role of the radiative and collisional processes in this plasma region, it is essential to have available detailed and quantitative knowledge on the corresponding elementary reactions proceeding in the volume and at the wall. Today's situation in terms of accurate data on these processes is far from satisfying. The plasma and materials physics group pursues three areas of research in order to provide quantitative information involving various plasma edge constituents:

1. Experimental studies about the ionization of neutrals and ions (cross sections, ionization energies, kinetic energy releases);
2. Theoretical studies about the ionization of neutrals and ions (cross sections) and;
3. Reactive interaction (erosion) of molecular ions with surfaces (elastic scattering, chemical sputtering, dissociation, chemical reactions).

These studies are carried out with four different experimental set-ups, including crossed-beams apparatus (using high resolution electron beams, atomic and molecular beams) in combination with high resolution mass spectrometry.

All activities since 15 Nov. 1996 have been performed within the Association EURATOM-OEAW.

Research activities:
The laboratory consists at present of three experimental devices, the Innsbruck Q-machine (''quiescent plasma machine''-IQ), the Innsbruck DP-machine (''double plasma machine''-IDP) and a test chamber.

International collaborations: ISTTOK group, Instituto Superior Técnico (Lisbon, Portugal), CASTOR tokamak group at the Czech Academy of Sciences (Prague, Czech Republic), Probe and Particle Physics Group at CIEMAT (Madrid, Spain).

Fields of Research

• Electrostatic edge plasma turbulence in magnetised plasmas: By means of electron emissive probes the true value of the plasma potential and its fluctuations are determined in the SOL of smaller fusion devices (see collaboration partners listed above);
• Non-linear potential structures in plasmas: Anode double layers, fireballs, potential relaxation instability, electrostatic ion-cyclotron instability;
• Electron current-driven low-frequency instabilities: Universal drift instability and electron current drift instability.

Work on test and development of electron-emissive probes has been performed since 15 Nov. 1996 within the Association EURATOM-OEAW.
