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…
An upper pressure limit for low-Z benign termination of runaway electron beams in TCV
M Hoppe, J Decker, U Sheikh +17
We present a model for the particle balance in the post-disruption runaway electron plateau phase of a tokamak discharge. The model is constructed with the help of, and applied to,…
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…
Tomographic reconstruction of the runaway distribution function in TCV using multispectral synchrotron images
T. A. Wijkamp, A. Perek, J. Decker +8
Synchrotron radiation observed in a quiescent TCV runaway discharge is studied using filtered camera images targeting three distinct wavelength intervals. Through the tomographic S…
Runaway electron synchrotron radiation in a vertically translated plasma
M. Hoppe, G. Papp, T. Wikjamp +6
Synchrotron radiation observed from runaway electrons (REs) in tokamaks depends upon the position and size of the RE beam, the RE energy and pitch distributions, as well as the loc…
