Development of an 11-channel multi wavelength imaging diagnostic for divertor plasmas in MAST Upgrade

Basil Duval, Yanis Andrebe, Artur Perek, Wouter Vijvers

Divertor detachment and alternative divertor magnetic geometries are predicted to be promising approaches to handle the power exhaust of future fusion devices. In order to understand the detachment process caused by volumetric losses in alternative diverto ...

Development of a real-time algorithm for detection of the divertor detachment radiation front using multi-spectral imaging

Christian Gabriel Theiler, Artur Perek, Kevin Henricus Annemarie Verhaegh, Wouter Vijvers

In this paper we present a novel algorithm to extract the optical plasma boundary and radiation front for detached divertor plasmas. We show that reliable detection of the divertor leg and radiation front is possible using lightweight image processing tool ...

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, Benoît Labit, Christian Gabriel Theiler, Umar Sheikh, Marco Wischmeier, Nicola Vianello, Cedric Kar-Wai Tsui, Kevin Henricus Annemarie Verhaegh, Wouter Vijvers, Roberto Maurizio, Mirko Wensing, Hugo De Oliveira

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 ...
