Performance assessment of a tightly baffled, long-legged divertor configuration in TCV with SOLPS-ITER

Basil Duval, Holger Reimerdes, Christian Gabriel Theiler, Guang-Yu Sun, Olivier Claude Martin Février, Claudia Colandrea

Numerical simulations explore a possible tightly baffled, long-legged divertor (TBLLD) concept in a future upgrade of the tokamak à configuration variable (TCV). The SOLPS-ITER code package is used to compare the exhaust performance of several TBLLD config ...

Power exhaust and core-divertor compatibility of the baffled snowflake divertor in TCV

Basil Duval, Holger Reimerdes, Christian Gabriel Theiler, Umar Sheikh, Luke Simons, Olivier Claude Martin Février, Sophie Danielle Angelica Gorno, Claudia Colandrea

A baffled snowflake minus low-field side (SF-LFS) is geometrically-optimised in tokamak a` configuration variable, increasing divertor neutral pressure, to evaluate the roles of divertor closure (comparing with an unbaffled SF-LFS) and magnetic geometry (c ...

Maximum likelihood bolometry for ASDEX upgrade experiments

Olivier Claude Martin Février, Riccardo Rossi

Bolometry is an essential diagnostic for calculating the power balances and for the understanding of different physical aspects of tokamak experiments. The reconstruction method based on the Maximum Likelihood (ML) principle, developed initially for JET, h ...

X-point and divertor filament dynamics from gas puff imaging on TCV

Basil Duval, Christian Gabriel Theiler, Olivier Claude Martin Février, Davide Galassi, Curdin Tobias Wüthrich, Nicola Offeddu

A new gas puff imaging diagnostic has been installed on the TCV tokamak, providing two-dimensional insights into scrape-off-layer (SOL) turbulence dynamics above, at and below the magnetic X-point. A detailed study in L-mode, attached, lower single-null di ...

Systematic extraction of a control-oriented model from perturbative experiments and SOLPS-ITER for emission front control in TCV

Artur Perek, Olivier Claude Martin Février, Mirko Wensing

Systematic extraction of locally valid dynamic models from experiments is necessary for controller design and the validation of high fidelity models. This paper describes the extraction of a dynamic model in the form of a transfer function, giving the dyna ...

Overview of the TCV tokamak experimental programme

Olivier Sauter, Ambrogio Fasoli, Basil Duval, Timothy Goodman, Jonathan Graves, Yves Martin, Jean-Marc Moret, Stefano Alberti, Ivo Furno, Duccio Testa

The tokamak a configuration variable (TCV) continues to leverage its unique shaping capabilities, flexible heating systems and modern control system to address critical issues in preparation for ITER and a fusion power plant. For the 2019-20 campaign its c ...

Gas puff imaging on the TCV tokamak

Basil Duval, Christian Gabriel Theiler, Cristian Galperti, Jean-Daniel Landis, Yanis Andrebe, Olivier Claude Martin Février, Robert Bertizzolo, Curdin Tobias Wüthrich, Nicola Offeddu

We present the design and operation of a suite of Gas Puff Imaging (GPI) diagnostic systems installed on the Tokamak a Configuration Variable (TCV) for the study of turbulence in the plasma edge and Scrape-Off-Layer (SOL). These systems provide the unique ...

Power exhaust by core radiation at COMPASS tokamak

Olivier Claude Martin Février, Davide Mancini

Substantial power dissipation in the edge plasma is required for the safe operation of ITER and next-step fusion reactors, otherwise unmitigated heat fluxes at the divertor plasma-facing components (PFCs) would easily exceed their material limits. Traditio ...
