A quasi-isodynamic configuration with good confinement of fast ions at low plasma
E. Sánchez, J. L. Velasco, I. Calvo +1
A new quasi-isodynamic stellarator configuration optimized for the confinement of energetic ions at low plasma is obtained. The numerical optimization is carried out using the…
First-principles based plasma profile predictions for optimized stellarators
A. Bañón Navarro, A. Di Siena, J. L. Velasco +6
In the present Letter, first-of-its-kind computer simulations predicting plasma profiles for modern optimized stellarators -- while self-consistently retaining neoclassical transpo…
Prevention of core particle depletion in stellarators by turbulence
H. Thienpondt, J. M. García-Regaña, I. Calvo +11
In reactor-relevant plasmas, neoclassical transport drives an outward particle flux in the core of large stellarators and predicts strongly hollow density profiles. However, this t…
Energetic particle loss mechanisms in reactor-scale equilibria close to quasisymmetry
E. J. Paul, A. Bhattacharjee, M. Landreman +3
Collisionless physics primarily determines the transport of fusion-born alpha particles in 3D equilibria. Several transport mechanisms have been implicated in stellarator configura…
Finite orbit width effects in large aspect ratio stellarators
Vincent d'Herbemont, Felix I. Parra, Ivan Calvo +1
New orbit averaged equations for low collisionality neoclassical fluxes in large aspect ratio stellarators with mirror ratios close to unity are derived. The equations retain finit…
