Reducing turbulent transport in tokamaks by combining intrinsic rotation and the low momentum diffusivity regime

Autor: Sun, Haomin, Ball, Justin, Brunner, Stephan, Field, Anthony, Patel, Bhavin, Kennedy, Daniel, Roach, Colin, Cruz-Zabala, Diego Jose, Del Pozo, Fernando Puentes, Viezzer, Eleonora, Munoz, Manuel Garcia

Based on the analysis of a large number of high-fidelity nonlinear gyrokinetic simulations, we propose a novel strategy to improve confinement in tokamak plasmas by combining up-down asymmetric flux surface shaping with the Low Momentum Diffusivity (

Physics of the low momentum diffusivity regime in tokamaks and its experimental applicability

Autor: Sun, Haomin, Ball, Justin, Brunner, Stephan, Field, Anthony, Patel, Bhavin, Balestri, Alessandro, Kennedy, Daniel, Roach, Colin, Cruz-Zabala, Diego Jose, Del Pozo, Fernando Puentes, Viezzer, Eleonora, Munoz, Manuel Garcia

Strong $E\times B$ plasma flow shear is beneficial for reducing turbulent transport. However, traditional methods of driving flow shear do not scale well to large devices such as future fusion power plants. In this paper, we use a large number of non

Physical insights from the aspect ratio dependence of turbulence in negative triangularity plasmas

Autor: Balestri, Alessandro, Ball, Justin, Coda, Stefano, Cruz-Zabala, Diego Jose, Garcia-Munoz, Manuel, Viezzer, Eleonora

In this work, we study the impact of aspect ratio A = R0 /r (the ratio of major radius R0 to minor radius r) on the confinement benefits of Negative Triangularity (NT) plasma shaping. We use high-fidelity flux tube gyrokinetic GENE simulations and co

Prospects of Core–edge Integrated No-ELM and Small-ELM Scenarios for Future Fusion Devices

Autor: Viezzer, Eleonora, Austin, M. E., Bernert, M., Burrell, K. H., Cano Megías, Pilar, Chen, X., Cruz Zabala, Diego José, Coda, S., Faitsch, M., Février, O., Oyola Domínguez, Pablo, Solano, E. R.

One of our grand challenges towards fusion energy is the achievement of a high-performance plasma core coupled to a boundary solution. The high confinement mode (H-mode) provides such a high-performance fusion core due to the build-up of an edge tran

Edge poloidal impurity asymmetry studies using gas puff based charge exchange recombination spectroscopy at the ASDEX Upgrade tokamak

Autor: Cruz Zabala, Diego José

Nuclear fusion, the energy source of the stars, is expected to be a clean and abundant source of energy on Earth in the near future. However, fusion reactors have to face different challenges due to the high temperatures required to reach ignition. O
