Neutral pressure measurement in TCV tokamak using ASDEX-type pressure gauges

Holger Reimerdes, Marcelo Baquero Ruiz, Guang-Yu Sun, Elena Tonello, Marc Noël, Mateusz Gospodarczyk, Hammam Elaian

Probing the neutral gas distribution at the edge of magnetic confinement fusion devices is critical for plasma exhaust studies. In the TCV tokamak, a set of ASDEX-type hot ionization pressure gauges (APGs) has been installed for fast, in situ measurements ...

SOLPS-ITER validation with TCV L-mode discharges

Basil Duval, Patrick Blanchard, Holger Reimerdes, Christian Gabriel Theiler, Marco Wischmeier, Cedric Kar-Wai Tsui, Kevin Henricus Annemarie Verhaegh, Mirko Wensing, Marcelo Baquero Ruiz, Artur Perek, Hugo De Oliveira, Filippo Bagnato, Lorenzo Martinelli, Sophie Danielle Angelica Gorno, Claudia Colandrea

This work presents a quantitative test of SOLPS-ITER simulations against tokamak a configuration variable (TCV) L-mode experiments. These simulations account for drifts, currents, kinetic neutrals, and carbon impurities providing the most complete edge tra ...

Initial TCV operation with a baffled divertor

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

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

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

Truncated Levy motion through path integrals and applications to nondiffusive suprathermal ion transport

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Marcelo Baquero Ruiz, Oulfa Chellaï, Fabian Manke

Fractional Levy motion has been derived from its generalized Langevin equation via path integrals in earlier works and has since proven to be a useful model for nonlocal and non-Markovian processes, especially in the context of nondiffusive transport. Here ...

A birdcage resonant antenna for helicon wave generation in TORPEX

Ivo Furno, Alan Howling, Robert Bertizzolo, Marcelo Baquero Ruiz, Philippe Frédérique Bruno Guittienne, Rémy Jacquier, Simon Pierre Henri Vincent, Cyrille Joseph Sepulchre, Patrick Campbell Quigley

A birdcage resonant helicon antenna is designed, mounted, and tested in the toroidal device TORPEX. The birdcage resonant antenna is an alternative to the usual Boswell or half-helical antenna designs commonly used for ∼ 10 cm diameter helicon sources in l ...

Modelling of sawtooth-induced fast ion transport in positive and negative triangularity in TCV

Olivier Sauter, Basil Duval, Duccio Testa, Alexander Karpushov, Mario Ludovico Podesta, Antoine Pierre Emmanuel Alexis Merle, Marcelo Baquero Ruiz, Matteo Vallar, Dmytry Mykytchuk, Lorenzo Stipani

Internal kinks are a common magneto hydro-dynamic (MHD) instability observed in tokamak operation when the q profile in the plasma core is close to unity. This MHD instability impacts both the transport of the bulk plasma (current, particle and energy tran ...

Cathodoluminescent screen imaging system for seeded blob detection in toroidal plasma experiment

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Paul Bowen, Marcelo Baquero Ruiz, Fabian Manke, Carlos Morais, Paolo Micheletti

We designed and built a diagnostic based on a cathodoluminescent screen for the detection of turbulent plasma structures with high spatial resolution. The screen is coated with a low threshold energy cathodoluminescent powder that emits light when exposed ...

A new FILDSIM model for improved velocity-space sensitivity modelling and reconstructions

Marcelo Baquero Ruiz, Jesús Poley Sanjuán

We present a new version of the FILDSIM code (Galdon-Quiroga et al 2018 Plasma Phys. Control. Fusion 60 105005), which significantly refines the modelling of the fast-ion loss detector (FILD) signal. We demonstrate that the FILD weight functions computed u ...

4D and 5D phase-space tomography using slowing-down physics regularization

Marcelo Baquero Ruiz, Dmytry Mykytchuk, Jacob Emil Mencke

We compute reconstructions of 4D and 5D fast-ion phase-space distribution functions in fusion plasmas from synthetic projections of these functions. The fast-ion phase-space distribution functions originating from neutral beam injection (NBI) at TCV and We ...
