Initial observations in X-point target divertor discharges on MAST-U
N. Lonigro, K. Verhaegh, J. Harrison +14
The first high-power (> 3 MW) H-mode experiments using a double-null X-point-target (XPT) divertor configuration have been performed on MAST-U. The XPT geometry is obtained by comb…
2D electron density profile evolution during detachment in Super-X divertor L-mode discharges on MAST-U
N. Lonigro, R. S. Doyle, K. Verhaegh +12
2D electron density profiles obtained from coherence imaging spectroscopy in different MAST-U divertor conditions are compared. The data includes variations of strike point positio…
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…
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 2D electron density measurements using Coherence Imaging Spectroscopy in the MAST-U Super-X divertor
N. Lonigro, R. Doyle, J. S. Allcock +11
2D profiles of electron density and neutral temperature are inferred from multi-delay Coherence Imaging Spectroscopy data of divertor plasmas using a non-linear inversion technique…
