Collaborating with CIEMAT and Aalto University on modelling of fast ions in TJ-II stellarator

From 22 July to 2 August, we enjoyed the visits of two PhD students, Sadig Mulas and Joona Kontula from CIEMAT and Aalto University, respectively, to our group. Sadig and Joona came to work with us within the collaboration between the three institutions (CIEMAT – Aalto University – BSC) on numerical modelling of fast ions in the TJ-II stellarator. The TJ-II stellarator is an experimental fusion device is located at the CIEMAT headquarters in Madrid, Spain, which uses fast ions injected by neutral beam injection to heat the plasma.

The union of the three institutions results in a great scenario for collaboration: CIEMAT provides the experimental machine, the TJ-II stellarator, and the corresponding experimental results; Aalto University provides the numerical code ASCOT to simulate the dynamics of the particles; and BSC provides the computational support with MareNostrum4 together with experience in fast ions and their modelling.

Our work was mainly focused on the first estimations of the current driven by neutral beam injected ions in TJ-II with ASCOT. Our first results will be reported by Sadig in September at the 22nd International Stellarator and Heliotron Workshop, Madison, WI, 2019, organized by University of Wisconsin-Madison.

We are grateful to the HPC-Europa3 Transnational Access programme and EUROfusion Education and Training Work Package for the funding  Joona’s and Sadig’s visits, respectively, and we look forward to welcoming them again for their second visit in October.
