Shafranov shift and finite effects on Alfvén Eigenmodes and microinstabilities in global electromagnetic gyrokinetic simulations
B. Rofman, G. Di Giannatale, A. Mishchenko +8
Future nuclear fusion reactors will have to confine plasma with strong kinetic gradients and small fractions of fusion-born energetic particles (EP) that are ~100 times hotter than…
Role of Shafranov shift, zonal structures on the behavior of TAEs, AAEs and microinstabilities in the presence of energetic particles
B. Rofman, G. Di Giannatale, A. Mishchenko +8
In future nuclear fusion reactors, even a small fraction of fusion-born energetic particles (EP) about 100 times hotter than the thermal bulk species, contributes substantially to…
Global electromagnetic gyrokinetic simulations of internal transport barriers in reversed-shear tokamaks
Giovanni Di Giannatale, Arnas VolÄokas, Justin Ball +6
This work aims at improving our understanding of the conditions enabling the development of an Internal transport barriers (ITB), using a more comprehensive physical model, includi…
Turbulence-Induced Safety Factor Profile Flattening at Rational Surfaces in Tokamaks with Low Magnetic Shear
Arnas VolÄokas, Justin Ball, Giovanni Di Giannatale +1
In this paper, we investigate the effects of ion-scale turbulence-generated currents on the local safety factor profile under conditions of low magnetic shear and proximity to rati…
