Evidence on the effects of main-chamber neutrals on density shoulder broadening

Basil Duval, Holger Reimerdes, Christian Gabriel Theiler, Umar Sheikh, Marcelo Baquero Ruiz, Artur Perek, Nicola Vianello, Cedric Kar-Wai Tsui, Mirko Wensing, Sophie Danielle Angelica Gorno

Evidence that density shoulder broadening is dependent on high main-chamber neutral density is presented. Shoulder broadening does notoccur when the sources for main-chamber neutrals are minimized using divertor baffles and wide gaps to the first wall (sim ...

Initial TCV operation with a baffled divertor

Ambrogio Fasoli, Holger Reimerdes, Basil Duval, Jean-Marc Moret, Duccio Testa, Patrick Blanchard, Christian Gabriel Theiler, Umar Sheikh, Matthieu Toussaint, Marcelo Baquero Ruiz

The Tokamak à Configuration Variable (TCV) tokamak is in the midst of an upgrade to further its capability to investigate conventional and alternative divertor configurations. To that end, modular and removable gas baffles have been installed to decrease t ...

Measurement of the 2D emission profiles of hydrogen and impurity ions in the TCV divertor

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

Plasma emission of hydrogen and impurities is measured with use of filtered camera imaging in TCV divertor. The measurement technique is discussed in detail including: selection choice of filters, the absolute calibration procedure and the tomographic inve ...

Numerical investigation of optimal divertor gas baffle closure on TCV

Stefano Coda, Holger Reimerdes, Benoît Labit, Christian Gabriel Theiler, Davide Galassi, Mirko Wensing

A first set of divertor gas baffles has recently been installed in the TCV tokamak. In order to explore the physics determining the benefits and limitations of divertor baffling and to guide the design of a possible second generation of baffles, the effect ...

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 ...
