TAE Technologies, Inc. (TAE) pursues an alternate approach to magnetically-confined fusion, relying on field-reversed configuration (FRC) plasmas.
Fast Ion Stabilization of the Internal Tilt Mode in C-2W
November 2021 | T. DeHaas | APS-DPP 2021 | Poster
Traditional FRCs are known to be theoretically unstable to an internal tilt mode whose threshold is characterized by the parameter S*/E.
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…

Long-lived, hot FRCs with excluded flux radius up to 50 cm are sustained in steady-state in the central confinement vessel by utilizing several advanced subsystems.
Upgraded Diagnostic Array for End Losses from C-2W’s Open Field Line Plasma
November 2021 | M. Griswold | APS-DPP 2021 | Poster
An upgraded array of energy analyzers and bolometers has been installed in the divertors of C-2W to measure axial power losses as well as the electron temperature and ion energy distribution function (IEDF) of the plasma at the termination point of the open field lines. relatively large Larmor radius.
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.
