Nuclear fusion using magnetic confinement, in particular in the tokamak configuration, is a promising path towards sustainable energy. A core challenge is to shape and maintain a high-temperature plasma within the tokamak vessel. This requires high-dimensi ...

Initial TCV operation with a baffled divertor

Ambrogio Fasoli, Basil Duval, Jean-Marc Moret, Duccio Testa, Patrick Blanchard, Holger Reimerdes, Christian Gabriel Theiler, Umar Sheikh, Matthieu Toussaint, Marcelo Baquero Ruiz, Artur Perek, Sophie Danielle Angelica Gorno, Claudia Colandrea, Davide Galassi, Cedric Kar-Wai Tsui, Roberto Maurizio, Mirko Wensing, Hugo De Oliveira, Filippo Bagnato, Lorenzo Martinelli, Harshita Raj

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 ...

Thermal, electromagnetic and structural analysis of gas baffles for the TCV divertor upgrade

Basil Duval, Jean-Marc Moret, Holger Reimerdes, Christian Gabriel Theiler, Matthieu Toussaint, Dario Vaccaro

As part of an ongoing divertor upgrade of the TCV tokamak it is planned to add gas baffles to form a divertor chamber of variable closure. The baffles promise to increase the compression of neutral particles in the divertor and, thereby, extend the researc ...

Real time magnetic control of the snowflake plasma configuration in the TCV tokamak

Stefano Coda, Jean-Marc Moret, Holger Reimerdes, Benoît Labit, Federico Alberto Alfredo Felici, Cristian Galperti, Roberto Maurizio, Himank Anand

The novel plasma position and shape controller of the TCV tokamak aids in the precise control of complex configurations such as snowflake (SF) divertors. The ability of the controller design to simultaneously control the position, shape, divertor leg and X ...

In this paper we validate the finite element code RAPLICASOL, which models radiofrequency wave propagation in edge plasmas near ICRF antennas, against calculations with the TOPICA code. We compare the output of both codes for the ASDEX Upgrade 2-strap ante ...

The aim of this paper is to present a signal processing algorithm that, applied to the raw Locked Mode signal, allows us to obtain a disruption indicator in principle exploitable on different tokamaks. A common definition of such an indicator for different ...
