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…

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.
