SOLPS-ITER simulations of the TCV divertor upgrade

Basil Duval, Holger Reimerdes, Christian Gabriel Theiler, Artur Perek, Marco Wischmeier, Davide Galassi, Kevin Henricus Annemarie Verhaegh, Mirko Wensing

The effect of the upcoming TCV divertor upgrade on the distribution of neutrals and the onset of detachment is studied using 2D transport code simulations. The divertor upgrade is centered around the installation of a gas baffle to form a divertor chamber ...

Novel inferences of ionisation and recombination for particle/power balance during detached discharges using deuterium Balmer line spectroscopy

Basil Duval, Kevin Henricus Annemarie Verhaegh, Mirko Wensing

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 a full particle/power balance measurement of the divertor. This supplies ne ...

Conduction-based model of the Scrape-Off Layer power sharing between inner and outer divertor in diverted low-density tokamak plasmas

Basil Duval, Holger Reimerdes, Christian Gabriel Theiler, Benoît Labit, Mirko Wensing, Umar Sheikh, Marco Wischmeier, Nicola Vianello, Cedric Kar-Wai Tsui, Kevin Henricus Annemarie Verhaegh

A simple analytic model for the repartition of the Scrape-Off Layer (SOL) exhaust power between the inner and outer divertors in a diverted low-density tokamak plasma is introduced. Electron heat conduction is assumed to dominate the heat transport, from t ...
