Machine learning methods for modelling local, linear gyrokinetic simulations of MAST-U pedestal turbulence
Anna Niemelä, Daniel Jordan, Aaro Järvinen +8
Gyrokinetic (GK) stability strongly influences the performance of high-confinement-mode pedestals in spherical tokamak plasmas. High-fidelity gyrokinetic codes such as GENE can mod…
First demonstration of Super-X divertor exhaust control for transient heat load management in compact fusion reactors
B. Kool, K. Verhaegh, G. L. Derks +14
Nuclear fusion could offer clean, abundant energy. However, managing the immense power exhausted from the core fusion plasma towards the divertor remains a major challenge. This is…
First Ion Temperature Measurements in the MAST-U Divertor via Retarding Field Energy Analyzer
Y. Damizia, S. Elmore, P. Ryan +5
This study presents the first ion temperature (\(T_i\)) measurements from the MAST-U divertor using a Retarding Field Energy Analyzer (RFEA). Embedded within the flat tile of the c…
Initial Fulcher band observations from high resolution spectroscopy in the MAST-U divertor
N. Osborne, K. Verhaegh, M. D. Bowden +8
High resolution Fulcher band spectroscopy was used in the MAST-U divertors during Super-X and elongated conventional divertor density ramps with fuelling from the mi…
