𝑋-Point Target Radiator Regime in Tokamak Divertor Plasmas

Basil Duval, Holger Reimerdes, Christian Gabriel Theiler, Artur Perek, Luke Simons, Garance Hélène Salomé Durr-Legoupil-Nicoud, Daniele Hamm, Francesco Pastore, Sophie Danielle Angelica Gorno, Curdin Tobias Wüthrich

Fusion plasma regimes with a strongly radiating magnetic 𝑋 point are promising candidates to tackle the outstanding power exhaust challenge in reactor-scale devices. In this Letter, we report on a new type of 𝑋-point radiator, the XPTR (𝑋-point target radi ...

Interpretation of divertor ion temperature measurements from an attached towards a detached regime

Basil Duval, Patrick Blanchard, Holger Reimerdes, Christian Gabriel Theiler, Artur Perek, Luke Simons, Christine Stollberg, Olivier Claude Martin Février, Lorenzo Martinelli, Sophie Danielle Angelica Gorno

We present simultaneous profiles of the poloidal distribution of electron temperature and density (Te, ne), the poloidal emissivity distributions of a range of spectral lines together with the corresponding ion temperatures, Ti, in the TCV divertor plasma. ...

Access to an ELM-suppressed X-point radiator regime in TCV snowflake minus configurations

Basil Duval, Holger Reimerdes, Christian Gabriel Theiler, Artur Perek, Guang-Yu Sun, Luke Simons, Daniele Hamm, Olivier Claude Martin Février, Sophie Danielle Angelica Gorno, Curdin Tobias Wüthrich

TCV’s operating regime with an X-point radiator (XPR) has been broadened by changing the magnetic geometry. XPRs have properties that could make them an attractive power exhaust solution for fusion reactors. These include the conversion of a high fraction ...

Comparison of detachment in Ohmic plasmas with positive and negative triangularity

Olivier Sauter, Basil Duval, Stefano Coda, Holger Reimerdes, Christian Gabriel Theiler, Laurie Porte, Artur Perek, Garance Hélène Salomé Durr-Legoupil-Nicoud, Olivier Claude Martin Février, Sophie Danielle Angelica Gorno

In recent years, negative triangularity (NT) has emerged as a potential high-confinement L-mode reactor solution. In this work, detachment is investigated using core density ramps in lower single null Ohmic L-mode plasmas across a wide range of upper, lowe ...

X-point radiator and power exhaust control in configurations with multiple X-points in TCV

Holger Reimerdes, Christian Gabriel Theiler, Federico Alberto Alfredo Felici, Antoine Pierre Emmanuel Alexis Merle, Artur Perek, Guang-Yu Sun, Luke Simons, Garance Hélène Salomé Durr-Legoupil-Nicoud, Olivier Claude Martin Février, Filippo Bagnato

Novel power exhaust solutions are being developed to address the challenge of integrating a high performance fusion core plasma with a well-protected divertor, if the single null configuration does not scale to a reactor device. This work aims to elucidate ...

Modelling of power exhaust in TCV positive and negative triangularity L-mode plasmas

Holger Reimerdes, Christian Gabriel Theiler, Garance Hélène Salomé Durr-Legoupil-Nicoud, Olivier Claude Martin Février, Sophie Danielle Angelica Gorno

L-mode negative triangularity (NT) operation is a promising alternative to the positive triangularity (PT) H-mode as a high-confinement edge localised mode-free operational regime. In this work, two TCV Ohmic L-mode core density ramps with opposite triangu ...
