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.
Recent Progress in Simulation and Theory of the C-2W Experiment and Beyond
June 2022 | A.Necas | TOFE | Poster
The C-2W experiment is a FRC with the addition of external actuators including NB injection, EB, and magnetic expander divertors to provide SOL pumping
Ion temperature effects on plasma flow in the magnetic mirror configuration
November 2022 | A. Sabo | Physics of Plasmas | Paper
Effects of finite ion temperature on the plasma flow in the converging–diverging magnetic field, the magnetic mirror, or equivalently,
magnetic nozzle configuration are studied using a quasineutral paraxial two-fluid MHD model with isothermal electrons and warm magnetized ions.
Kinetic Simulation of Recycling Bifurcation in an Expander Divertor
November 2021 | S. Dettrick | APS-DPP 2021 | Poster
An expander divertor can be used to expand the Scrape-Off-Layer flux-tube of a linear device to arbitrary size, providing reduced energy flux to the wall, increased pumping capacity, formation of a pre-sheath for electrostatic confinement of electrons, and…
Neighboring equilibria and integrity of elongated FRC configurations
November 2021 | L. Zakharov | APS-DPP 2021 | Poster
In the TAE C-2W experiment, confinement and stability of Field Reversed Configurations (FRC) relies on the presence of energetic ions from neutral beam injection and their relatively large Larmor radius.
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.
