Petra Kluger, Prof. Dr.

The IGVP takes an interdisciplinary approach at the intersection of materials science, life sciences, and engineering, developing sustainable processes and technologies for medicine, the environment, and industry, while leveraging its close collaboration with the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB, true to the guiding principle: Innovation happens at interfaces.

The IGVP hosts the stellarator TJ-K and has expertise in plasma dynamics, microwave heating, microwave diagnostics, and plasma diagnostics.

TJ-K

1999 - Present

Description

The experiment TJ-K is a fusion device of stellarator type. Although TJ-K was originally constructed to be operated with a fusion plasma, at IGVP it is operated with a low-temperature plasma. The reduced temperature enables probe measurements inside the plasma with high temporal and spatial resolution. At the same time, dimensionless plasma parameters, which control the turbulent dynamics, are similar to those in the edge region of fusion plasmas. Three microwave heating sources operating at different frequencies allow for plasma generation at background magnetic fields from 50 mT up to 500 mT. The research topics are on the one hand the investigation of plasma dynamics by multi-probe arrays and a high-speed camera and comparing the results with numerical simulations and on the other hand the experimental and numerical investigation of plasma-microwave interaction.
