Detachment dynamics and disturbance rejection in the TCV X-Point Target divertor
M. Winkel, K. Verhaegh, B. Kool +11
The X-Point Target divertor is an alternative divertor configuration with a secondary X-point in its divertor volume. In this work, we investigate the dynamic response and disturba…
Real-time Tomography-based Bayesian Inference from TCV Bolometry Data
D. Hamm, C. Theiler, L. Simons +3
Radiated power information is crucial to diagnose and optimize the performance of fusion plasmas. Traditionally, at the TCV tokamak, radiated power analysis has only ever been poss…
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…
Comparison of filament properties in real-size GBS simulations and experiments of TCV-X21
Y. Wang, C. Wüthrich, C. Theiler +7
A direct quantitative comparison of Scrape-Off Layer (SOL) filament properties from fluid turbulence simulations using the GBS code and from experiments on the TCV tokamak is perfo…
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…
