The development of reduced models provide efficient methods that can be used to perform
short term experimental data analysis or narrow down the parametric range of more …

This paper is dealing with the physics basis used for the design of the Divertor Tokamak Test
facility (DTT), under construction in Frascati (DTT 2019 DTT interim design report (2019)) …

In this paper we report on the implementation and verification of a phase-space resolved
energetic particle (EP) transport model. It is based on a first-principle theoretical framework …

In a tokamak fusion reactor operated at steady state, the equilibrium magnetic field is likely
to have reversed shear in the core region, as the noninductive bootstrap current profile …

This work provides a general description of the self-consistent energetic particle phase
space transport in burning plasmas, based on nonlinear gyrokinetic theory. The self …

The theory, development, and validation of reduced quasilinear models of gyrokinetic
turbulent transport in the closed flux surface core of tokamaks is reviewed. In combination …

Nonlinear simulations of Alfvén modes (AMs) driven by energetic particles (EPs) in the
presence of turbulence are performed with the gyrokinetic particle-in-cell code ORB5. The …

In this work, gyrokinetic theory of drift waves (DWs) self-regulation via the beat-driven zonal
flow (ZF) is presented, and finite diamagnetic drift frequency due to plasma nonuniformity is …

By employing both nonlinear gyrokinetic simulation and analytical theory, we have
investigated the effects of zonal (electromagnetic) fields on the energetic particle's (EPs) …

The Alfvén instability nonlinearly excited the energetic-particle-driven geodesic acoustic
mode on the ASDEX-Upgrade tokamak, as demonstrated experimentally. The mechanism of …
