Gyrokinetic transport driven by ubiquitous modes in LTX-like tokamak with ‘flat’ temperature

Laurent Villard, Emmanuel Lanti

A global, gyro-kinetic nonlinear study of the ubiquitous mode (UM) for Lithium Tokamak eXperiment (LTX)-like profiles, under flat electron and ion temperature scenarios is conducted using a global gyrokinetic model. Exact MHD equilibria with circular shape ...

Suppression of temperature-gradient-driven turbulence by sheared flows in fusion plasmas

Plamen Georgiev Ivanov

Starting from the assumption that saturation of plasma turbulence driven by temperature-gradient instabilities in fusion plasmas is achieved by a local energy cascade between a long-wavelength outer scale, where energy is injected into the fluctuations, an ...

L-H power threshold for neutral beam heated plasmas with Deuterium, Hydrogen, Helium and mixed ion species in TCV

Basil Duval, Yves Martin, Olivier Sauter, Alexander Karpushov, Benoît Labit, Alessandro Pau, Dmytry Mykytchuk, Artur Perek

A systematic study of the power threshold for L-H transition has been conducted in TCV. Only results from NB heated plasmas are reported. The dependencies of PLH on plasma current, plasma density and main ion species have been investigated. For Deuterium&# ...

Overview of the TCV digital real-time plasma control system and its applications

Basil Duval, Blaise Marlétaz, Olivier Sauter, Stefano Coda, Alexander Karpushov, Federico Alberto Alfredo Felici, Antoine Pierre Emmanuel Alexis Merle, Joan Decker, Marcelo Baquero Ruiz, Mengdi Kong, Francesco Carpanese, Federico Pesamosca, Anna Ngoc Minh Trang Vu, Aude Maier, Alessandro Pau, Mateusz Gospodarczyk, Benjamin Alexandre Vincent, Gino Marceca, Stefano Marchioni, Artur Perek, Luca Emmanuel Segovia

Real-time plasma control systems are at the heart of operation of modern tokamaks. The control system of the TCV tokamak has recently seen a major upgrade in terms of its hardware and software components. Control algorithms are entirely programmed and test ...
