The stellarator TJ-K is operated at the University of Stuttgart. Originally intended for operation at high temperatures (as TJ-IU in Madrid), it is now operated at low temperatures. This allows Langmuir probe measurements with good spatial and temporal resolution. This is important to study plasma turbulence, and we have a long standing collaboration with the TJ-K team.
