HELIOS · High Energy Laboratory for Magnetised Plasma Studies

The HELIOS project focuses on advancing the understanding of high-power, high-density expanding magnetised plasmas, with an emphasis on charged particle dynamics. The primary objective is to develop and experimentally test an innovative high-power radio-frequency plasma source with a magnetic nozzle, which will be used for topics spanning space propulsion technologies, fusion research and fundamental space plasma physics. Through a combination of advanced diagnostic techniques, the project seeks to address both unresolved plasma physics questions and engineering challenges related to high-density magnetised plasmas. A comprehensive experimental campaign will allow the investigation of the high-density plasma behaviour, with a particular focus on ion acceleration, charged-particle transport, and plume instabilities. Advanced diagnostic techniques, such as Laser-Induced Fluorescence, Thomson Scattering and custom-build high-density intrusive diagnostics, will be employed to characterise the plasma. The project will also include a significant data analysis phase, where the gathered experimental results will be interpreted. These results will lay the base for future research in plasma physics (with focus on space weather and fusion research), and spacecraft propulsion. International collaboration is a key component of HELIOS, with secondments at prestigious institutions like the Australian National University and Tohoku University. These collaborations will enable knowledge exchange and provide access to specialized expertise and resources, further enhancing the project’s outcomes. By leveraging this international expertise, the project aims to position Europe at the forefront of research in understanding the plasma behaviour in a magnetic field and its engineering applications. The ultimate goal of the project is to establish a world-class multidisciplinary laboratory environment in the EU that will serve as a hub for future research in experimental plasma physics.
