BSC Fusion Group Joins Fusion Panel at Cleantech Forum Europe

The session “Integrating Fusion into the EU Energy Roadmap” is starting at the Cleantech Forum Europe 2025 in Sitges, Spain with the introduction by the session organizer Zainab Gilani.

On 12 November 2025, BSC’s Fusion Group participated in a high-level panel discussion at the Cleantech Forum Europe 2025 in Sitges, Spain. The session, titled “Integrating Fusion into the EU Energy Roadmap,” brought together leading voices from research, industry, and policy to discuss Europe’s evolving role in the global fusion energy landscape.

The panel was moderated by Zainab Gilani (Cleantech Group) and included Mervi Mantsinen (Barcelona Supercomputing Center), Richard Kembleton (Gauss Fusion), and Pierre-Yves Chaffard (Fusion for Energy).

The 25th Topical Conference on Radio-Frequency Power in Plasmas took place from 19 to 22 May 2025 and attracted more than 130 participants. Our group leader, Mervi Mantsinen, delivered an invited talk at this conference reviewing key milestones from four decades of Ion Cyclotron Range of Frequencies (ICRF) physics on the Joint European Torus (JET), highlighting its significant contributions to fusion research and implications for future reactors.

JET, Europe’s leading tokamak device, has achieved exceptional performance surpassing its design specifications, operating with magnetic fields of up to 4 T, plasma currents of 7 MA, and auxiliary heating powers totalling 37 MW. Its versatile ICRF system, with a frequency range of 25–56 MHz, has enabled a wide array of heating and current drive experiments.

Our new journal paper in Nuclear Fusion on modeling of frequency-sweeping Alfvén modes

Alfvénic instabilities driven by energetic particles pose a challenge to the efficient operation of magnetic confinement fusion devices. These modes can dispel fast ions leading to the introduction of significant heat loads onto plasma facing components and degradation of overall plasma confinement. One class of Alfvénic instabilities known as reversed shear Alfvén eigenmodes (RSAEs) are of particular risk in devices with reversed shear rotational transform profiles. Reversed shear configurations have recently been of interest because of their enhancement to confinement quality. With this in mind, further study of RSAEs is necessary.
