Full-F turbulent simulation in a linear plasma device using a gyro-moment approach
Paolo Ricci, Baptiste Jimmy Frei
Simulations of plasma turbulence in a linear plasma device configuration are presented. These simulations are based on a simplified version of the gyrokinetic (GK) model proposed by Frei et al. [J. Plasma Phys. 86, 905860205 (2020)], where the full-F distr ...
Melville2024Error field detection and correction studies towards ITER operation
Olivier Sauter, Bernhard Sieglin, Leonardo Pigatto
In magnetic fusion devices, error field (EF) sources, spurious magnetic field perturbations, need to be identified and corrected for safe and stable (disruption-free) tokamak operation. Within Work Package Tokamak Exploitation RT04, a series of studies hav ...
Iop Publishing Ltd2024Gyrokinetic simulations of turbulence in magnetic fusion plasmas using a delta-f PIC scheme with evolving background
Using the GKEngine code which simulates an electrostatic plasma with adiabatic electron response under a sheared-slab geometry, an attempt at developing a hybrid approach between the delta-f and full-f schemes to describe plasma profiles exhibiting high fl ...
EPFL2024Nonlinear simulation of plasma turbulence using a gyrokinetic moment-based approach
Plasma turbulence plays a fundamental role in determining the performances of magnetic confinement fusion devices, such as tokamaks. Advances in computer science, combined with the development of efficient physical models, have significantly improved our u ...
EPFL2024Interpretative 3D MHD modelling of deuterium SPI into a JET H-mode plasma
Cristian Sommariva, Umar Sheikh, Haomin Sun, Mengdi Kong
The pre-thermal quench (pre-TQ) dynamics of a pure deuterium ( D 2 ) shattered pellet injection (SPI) into a 3 MA / 7 MJ JET H-mode plasma is studied via 3D non-linear MHD modelling with the JOREK code. The interpretative modelling captures the overall evo ...
Iop Publishing Ltd2024Disruption avoidance and investigation of the H-Mode density limit in ASDEX Upgrade
Alessandro Pau, Federico Alberto Alfredo Felici, Bernhard Sieglin
In recent years a strong effort has been made to investigate disruption avoidance schemes in order to aid the development of integrated operational scenarios for ITER. Within the EUROfusion programme the disruptive H-mode density limit (HDL) has been studi ...
Bristol2024Global fluid simulations of plasma turbulence in stellarators
António João Caeiro Heitor Coelho
In order to cope with the decarbonization challenge faced by many countries, fusion is one of the few alternatives to fossil fuels for the production of electricity. Two devices invented in the middle of the previous century have emerged as the most promis ...
EPFL2024Tangentially viewing phase contrast imaging for turbulence measurements in toroidal fusion devices
Phase contrast imaging (PCI) is an established and powerful technique for measuring density fluctuations in plasmas and has been successfully applied to several fusion devices. Rooted in a concept first developed for microscopy, PCI belongs to the category ...
