Theory and Simulation of High-Performance Beam-Driven FRCs
April 2016 | Sean Dettrick | Sherwood | Presentation
The TAE research program has been successful due to the agility and close interaction between experiment, theory, and engineering groups.
Transport simulations of the C-2 and C-2U Field Reversed Configurations with the Q2D code
April 2016 | Marco Onofri | Sherwood | Poster
The Q2D code is a 2D MHD code, which includes a neutral fluid and separate ion and electron temperatures, coupled with a 3D Monte Carlo code, which is used to calculate source terms due to neutral beams.
Control of ion gyroscale fluctuations via electrostatic biasing and sheared E×B flow in the C-2 field reversed configuration
March 2016 | L. Schmitz | AIP Conference Proceedings | Paper
Control of radial particle and thermal transport is instrumental for achieving and sustaining well-confined high-β plasma in a Field-Reversed Configuration (FRC). Radial profiles of low frequency ion gyro-scale density fluctuations (0.5 ≤ kρs ≤ 40), consistent with drift- or drift-interchange modes, have been measured in the scrape-off layer (SOL) and core of the C-2 Field-Reversed Configuration (FRC), together with the toroidal ExB velocity.
Robustness of waves with a high phase velocity
March 2016 | T. Tajima | AIP Conference Proceedings | Paper
Norman Rostoker pioneered research of (1) plasma-driven accelerators and (2) beam-driven fusion reactors. The collective acceleration, coined by Veksler, advocates to drive above-ionization plasma waves by an electron beam to accelerate ions. The research on this, among others, by the Rostoker group incubated the idea that eventually led to the birth of the laser wakefield acceleration (LWFA), by which a large and robust accelerating collective fields may be generated in plasma in which plasma remains robust and undisrupted.
End loss analyzer system for measurements of plasma flux at the C-2U divertor electrode
March 2016 | M. E. Griswold | AIP Conference Proceedings | Paper
An end loss analyzer system was developed to study thermal transport on the open field lines that surround the advanced beam-driven field-reversed configuration (FRC) core of the C-2U experiment. The system is mounted directly to the divertor electrode and consists of gridded retarding-potential analyzers that measure ion current density and ion energy as well as pyroelectric crystal bolometers that measure the total power flux.
Overview of C-2U FRC Experimental Program and Plans for C-2W
October 2016 | Hiroshi Gota | EPR2016 | Poster
The experimental program at TAE Technologies has been focused on a demonstration of reliable field-reversed configuration (FRC) formation and sustainment, driven by fast ions via high-power neutral-beam (NB) injection.
