RF dispersion relations in FRC geometries and HHFW regime

February 2024 | F. Ceccherini | Physics of Plasmas | Paper

Field reversed configurations (FRC) are characterized by a magnetic field topology, which exhibits the inversion of the external magnetic field through plasma sustained current and the subsequent presence of a null field surface

Stabilization of the Alfven-ion cyclotron instability through short plasmas: Fully kinetic simulations in a high-beta regime

October 2023 | B. Nicks | Physics of Plasmas | Paper

The Alfven-ion cyclotron (AIC) mode is an instability that can be driven in magnetized plasmas with anisotropic pressure. Its chief deleterious effect is the driving of enhanced pitch-angle scattering of ions

Potential development and electron energy confinement in an expanding magnetic field divertor geometry

August 2023 | S. Gupta | Physics of Plasmas | Paper

The formation of electrostatic potential in an expanding magnetic field divertor is numerically simulated using a kinetic model. As theoretically expected, the electrostatic potential is formed in the expanding magnetic field…
