Helicon waves in FRC configurations
October 2022 | F. Ceccherini | APS-DPP 2022 | Poster
The full-wave code RF_Pisa has been extended to model the so-called Helicon regime. These waves are whistler-type waves with a two-branch dispersion relation.
Evolution and consequences of orbit type distributions in FRCs
November 2021 | F. Ceccherini | APS-DPP 2021 | Poster
Field Reversed Configurations (FRCs) are characterized by particular electric and magnetic field geometries that are due to the presence of unique particle orbit types as so-called Betatron, Drift, Fig8 and Type 1 orbits.
RF Transfer of Momentum and Angular Momentum in FRC plasmas
November 2020 | F. Ceccherini | APS-DPP | Poster
TAE Technologies RF code, RF-Pisa, has been upgraded to study the transfer of momentum and angular momentum from RF waves to plasma species in an FRC configuration.
Onset of Tilt Instability in FRC Plasmas
October 2018 | F. Ceccherini | APS-DPP | Poster
Tilt instability in FRC plasmas1 is a well-known MHD phenomenon that has been extensively investigated over the years by different authors and an empirical scaling law
Propagation and dynamics of microwaves in the ECRH frequency range for the FRC
October 2014 | F. Ceccherini | APS-DPP | Poster
A previously developed Finite Larmor Radius (FLR) code for ICRH studies in cylindrical geometry has been recently extended to include the frequency range of interest for ECRH applications.
