Spectroscopic investigations of divertor detachment in TCV
K. Verhaegh, B. Lipschultz, B. P. Duval +13
The aim of this work is to provide an understanding of detachment at TCV with emphasis on analysis of the Balmer line emission. A new Divertor Spectroscopy System has been develope…
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…
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…
Experimental Divertor Similarity Database Parameters
I. H. Hutchinson, B. LaBombard, B. Lipschultz
A set of experimentally-determined dimensionless parameters is proposed for characterizing the regime of divertor operation. The objective is to be able to compare as unambiguously…
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…
Novel inferences of ionisation & recombination for particle/power balance during detached discharges using deuterium Balmer line spectroscopy
K. Verhaegh, B. Lipschultz, B. P. Duval +4
The physics of divertor detachment is determined by divertor power, particle and momentum balance. This work provides a novel analysis technique of the Balmer line series to obtain…
