The Barcelona Supercomputing Center (BSC) hosts one of the Advanced Computing Hub (ACH) that EUROfusion has created to improve fusion codes following its European Research Roadmap. These codes are essential for advancing fusion energy research, which is a promising sustainable energy source for the future.

On 11-15 March our group leader, ICREA Research Prof. Mervi Mantsinen visited the JET tokamak at Culham, United Kingdom, to take part in the Analysis and Modelling Meeting of the EUROfusion Work Package Tokamak Exploitation (WPTE). In total, approximately 85 fusion scientists from all around Europe participated in this meeting in person.
Unveiling the power of MAGNET for HTS simulation
In the realm of computational research, a new tool for HTS simulation has emerged: MAGNET. MAGNET stands as a revolutionary module designed for simulating the magnetic behavior of High Temperature Superconductors (HTS). Embedded within the renowned Alya suite, a software developed by the Barcelona Supercomputing Center (BSC) and optimized for High-Performance Computing (HPC), MAGNET has recently undergone benchmarking that unveils its potential.
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.

A recent study examines heat transport in stochastic magnetic fields, focusing on an-isotropic temperature diffusion. This research dives into the differences between parallel and perpendicular thermal conductivity.
Recent research on plasma heating by the Fusion Group
![](http://fusion.bsc.es/wp-content/uploads/logo_ppacf-400x95.png)
The Fusion Group has been working hard to improve our understanding of the deuterium-tritium (D-T) plasmas carried out at JET during late 2021. These experiments broke the world fusion energy record and are providing us with invaluable physical insight in preparation of ITER’s experiments.
Our research has culminated in two recent papers published at Plasma Physics and Controlled Fusion. One tackles the optimization of the H and 3He minority heating schemes for D-T, while the other describes a recent upgrade we developed for the calculation of the diffusion operator. A brief overview is given together with their links to the journal version as follows.
