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…
Constructing the space of quasisymmetric stellarators
Eduardo Rodriguez, Wrick Sengupta, Amitava Bhattacharjee
A simplified view of the space of optimised stellarators has the potential to guide and aid the design efforts of magnetic confinement configurations suitable for future fusion rea…
Research Opportunities in Plasma Astrophysics
Stuart Bale, Amitava Bhattacharjee, Fausto Cattaneo +13
Major scientific questions and research opportunities are described on 10 unprioritized plasma astrophysics topics: (1) magnetic reconnection, (2) collisionless shocks and particle…
On large-scale dynamos with stable stratification and the application to stellar radiative zones
Valentin Skoutnev, Jonathan Squire, Amitava Bhattacharjee
Our understanding of large-scale magnetic fields in stellar radiative zones remains fragmented and incomplete. Such magnetic fields, which must be produced by some form of dynamo m…
Phases and phase-transitions in quasisymmetric configuration space
Eduardo Rodriguez, Wrick Sengupta, Amitava Bhattacharjee
We explore the structure of the space of quasisymmetric configurations identifying them by their magnetic axes, described as 3D closed curves. We demonstrate that this topological…
Interplay of Three-Dimensional Instabilities and Magnetic Reconnection in the Explosive Onset of Magnetospheric Substorms
Samuel R. Totorica, Amitava Bhattacharjee
Magnetospheric substorms are preceded by a slow growth phase of magnetic flux loading and current sheet thinning in the tail. Extensive datasets have provided evidence of the trigg…
