A novel understanding of the role of plasma-molecular kinetics on divertor power exhaust
N. Osborne, K. Verhaegh, D. Moulton +12
During detachment, a buffer of neutral atoms and molecules builds up between the target and the ionising plasma. Collisions between the plasma and the molecules play an important r…
Divertor shaping with neutral baffling as a solution to the tokamak power exhaust challenge
K. Verhaegh, J. R. Harrison, D. Moulton +20
Exhausting power from the hot fusion core to the plasma-facing components is one of the biggest challenges in fusion energy. The MAST Upgrade tokamak uniquely integrates strong con…
Ion Temperature Measurements in the MAST-U Divertor During Steady State Plasmas and ELM Burn Through Phenomena
Y. Damizia, S. Elmore, K. Verhaegh +7
This study presents ion temperature (\(T_i\)) measurements in the MAST-U divertor, using a Retarding Field Energy Analyzer (RFEA). Steady state measurements were made during an L-M…
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…
Predictive power-sharing scaling law in double-null L-mode plasmas
K. Lim, P. Ricci, L. Stenger +5
The physical mechanisms regulating the power sharing at the outer targets of L-mode double-null (DN) configurations are investigated using nonlinear, flux-driven, three-dimensional…
