On January 14, our group leader Prof. Mervi Mantsinen had the honour of chairing the evaluation panel of Mathias Hoppe’s thesis entitled “Runaway-electron model development and validation in tokamaks” at the Chalmers University of Technology, Gothenburg, Sweden.

Super fast electrons, so called “runaway electrons”, can sometimes appear in fusion devices and can cause severe damage to the device wall. To develop technologies to prevent the generation of runaway electrons, advanced computer models accounting for all the relevant physics mechanisms playing a role in a fusion device are required, which constitutes the first part of Mathias Hoppe’s thesis. To ensure that the models are correct they must also be tested on the fusion experiments of today, which can be done using synchrotron radiation and the techniques developed in the second part of Mathias Hoppe’s thesis.

Looking back to 2021 in our group

Collage of images from our most accessed posts and other highlights in 2021.

The year 2021 is coming to its end and it is time for us to take a small break to disconnect, rest and celebrate. We would like to thank all our followers for their continued interest in our work.

For us here at the BSC Fusion group it has been a good year despite being still affected by the COVID-19 pandemic in our daily lives, including our work.

Join us! We are looking for new group members for numerical modelling in fusion

We are looking for researchers in computational physics, computers science, engineering or related fields to join our Fusion group ( at the Department of Computer Applications in Science and Engineering (CASE) of Barcelona Supercomputing Center. The objective of our group is to enhance modelling capabilities in fusion by code development, validation, integration and optimization including the use of advanced HPC techniques.

We work closely towards the objectives of EUROfusion (, the European fusion research programme for Horizon 2020 and Horizon Europe, in collaboration with Fusion for Energy (F4E), ITER, International Tokamak Physics Activity, and the Spanish national fusion laboratory CIEMAT. Given the number of projects we are involved in, we have the possibility to match our project needs and the candidate interests and profile when deciding on the tasks to be carried out.

Please check here for more details and for a link to send in your application.

Join us for PRACE Summer of HPC 2021 on computational atomic-scale modelling of materials for fusion

Are you interested in collaborating with our Fusion group at Barcelona Supercomputing Center (BSC) during July and August 2021? PRACE Summer of HPC 2021 is now open for applications to late-stage undergraduate and Master’s students. The deadline for applications is March 15, 2021.

In this edition, BSC offers six projects to join. One of them is in our Fusion Group under the supervision of Dr Julio Gutiérrez and our group leader Prof. Dr Mervi Mantsinen.

The project is on computational atomic-scale modelling of materials for fusion reactors and it contributes to the efforts to mitigate climate change which is one of the most important humankind challenges at the time.
