  • Stellarator TJ-K

The experiment TJ-K is a fusion device of stellarator type, located at the Institute of Interfacial Process Engineering and Plasma Technology, Stuttgart (IGVP). 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.

Use and Access

Bachelor, master and doctoral theses are regularly performed at TJ-K. Topics for potential theses are provided upon request.
