AORSA 3D: new insight on ICRH in stellarators

Representation of last closed magnetic flux surfaces in a stellarator.

The tridimensional All-ORder Spectral Algorithm (AORSA-3D) has been adapted to run on the supercomputer MareNostrum, at the Barcelona Supercomputing Center – Centro Nacional de Supercomputación (BSC-CNS). AORSA-3D is designed to study the plasma-wave interaction inside the 3D volume of a stellarator. Its model provides fully three-dimensional solutions of the integral wave equation for Ion Cyclotron Resonance Heating (ICRH) in three-dimensional stellarator plasmas. Its algorithm is based on combining multiple periodic solutions for individual helical field periods in order to obtain complete 3-D wave solutions valid over the entire volume of the stellarator for an arbitrary antenna geometry.

4th Fusion HPC Workshop

On 29 and 30 November 2023, the Fusion Group at Barcelona Supercomputing Center (BSC) actively participated in the yearly workshop regarding research in HPC for Fusion, which has now arrived at its 4th edition.

The Workshop is meant to be a gathering appointment for experts in HPC in the research field of Nuclear Fusion. The covered topics were related to the different ways in which HPC methods and algorithms, spanning across Monte-Carlo methods, Neural Networks, and Parallelization Exploitation, can be extremely valuable for applications, going from the simulation of MHD instabilities to System Analysis, to reach efficient ways of energy production through Nuclear Fusion.

A total of 31 talks have been organized in 11 Zoom Sessions, giving life to an exhaustive program covering all the relevant topics. The 5 keynote talks, of great inspiration for the audience, were:

FuseNet Teacher Day 2023

Teacher Day 2023 announcement

The FuseNet Teacher Day is an annual event organized by FuseNet which closes the gap between research/industry and high school education. Its main purpose is to motivate students in the rich field of fusion physics and technology. It is typically addressed to professors, who receive a nice set of educational material and a gentle overview of fusion technology on the shoulders of the main research labs in each European country. 

We are happy at the Barcelona Supercomputing Center (BSC) to organize together with Fusion for Energy (F4E) the Catalan session, as done in previous editions (see here). This year the session has been covered by Dr Ferran Albajar (F4E) and Dr Dani Gallart (BSC). The Catalan session, which typically lasts 1 hour, is entirely devoted to the understanding of the key features and advantages that fusion technology has to offer. We also elaborate on the educational materials available and after that we engage in an interesting and enthusiastic discussion with all the audience. We appreciate the interest and the time that professors invest in our talk, and we hope all the material and motivation we try to send during the session is useful and ultimately transferred to the students. The students are the future of our society and so, of fusion technology as well.

Research stay at ITER

ITER facility.

From the 10th of April to the 13th of May, one of the members of our Fusion group, Tomas Bensadon, went on a research stay to the ITER Organization (IO) Headquarters in Cadarache, France. The research stay took place as an internship, under the 2022- INTERN-SCOP06- ICRH modelling in various scenarios of the ITER Research Plan program. This internship was made possible by the BSC Mobility Program, which was awarded to Tomas Bensadon on August 2022.
