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.
