Sweden

Swedish fusion research encompasses a range of competencies important for the ITER project’s long-term goal of achieving a prototype fusion reactor. Research is carried out at the Royal Institute of Technology (KTH) in Stockholm, Chalmers University of Technology in Göteborg, Uppsala University, Lund University and RISE (Research Institutes of Sweden).

Fusion research in Sweden is mainly carried out at universities and research institutes and is focused on fundamental research in areas such as transport of particles and energy, plasma stability (including active control of instabilities), heating (mainly Ion Cyclotron Resonant Heating), energetic particle physics, plasma wall interaction and materials studies, diagnostic development and implementations, in particular spectroscopy and neutron diagnostics, and accelerator physics. The research includes both experimental and theoretical work with a strong element of modelling, including innovative methods, and computer code development.

The key contributions of the Swedish researchers can be summarised in six areas:

• Confinement and pedestal physics
• Ion cyclotron range of frequency (ICRF) heating studies and Magnetohydrodynamic (MHD) control
• Fusion product studies and fast ions
• Plasma-wall interaction and the new ITER-like wall (ILW)
• Transport analysis of ILW and C-wall discharges
• Neutron emission spectroscopy
