Achieving a long-lived high-beta plasma state by energetic beam injection
April 2015 | H. Guo | Nature Communications | Paper
Developing a stable plasma state with high-beta (ratio of plasma to magnetic pressures) is of critical importance for an economic magnetic fusion reactor.
Improved Confinement of C-2 Field Reversed Configuration Plasmas
February 2015 | H. Gota | Fusion Science and Technology | Paper
C-2 is a unique, large compact-toroid (CT) device at TAE Technologies that produces field-reversed configuration (FRC) plasmas by colliding and merging oppositely directed CTs. Significant progress has recently been made on C-2, achieving ,5 ms stable plasmas with a dramatic improvement in confinement, far beyond the prediction from the conventional FRC scaling.
Feasibility study of microwave electron heating on the C-2 field-reversed configuration device
February 2015 | X. Yang | AIP Conference Proceedings | Paper
Different microwave heating scenarios for the C-2 plasmas have been investigated recently with use of both the Genray ray-racing code and the IPF-FDMC full-wave code, and the study was focused on the excitation of the electron Bernstein wave (EBW) with O-mode launch.
Development of Compact Toroid Injector for C-2 FRCs
October 30, 2014 | T. Matsumoto | APS-DPP | Poster
A collaborative research project with TAE Technologies has been started and we have developed a new compact toroid (CT) injector for the C-2 device, mainly for fueling field-reversed configurations (FRCs).

October 2014 | D. Gupta | APS-DPP | Poster
Measurements of ion temperature profile and its time evolution is important for the understanding of FRC confinement and transport properties.
Numerical study of rotational instabilities and beam ion effects in FRC using the HYM code
October 2014 | E. Belova | APS-DPP | Presentation
Numerical study of FRC spin-up and the effects of end-biasing on FRC stability has been performed using a 3D nonlinear hybrid version of the HYM code for TAE FRC experimental parameters.
Propagation and dynamics of microwaves in the ECRH frequency range for the FRC
October 2014 | F. Ceccherini | APS-DPP | Poster
A previously developed Finite Larmor Radius (FLR) code for ICRH studies in cylindrical geometry has been recently extended to include the frequency range of interest for ECRH applications.
Z-Effective from Bremsstrahlung Light in the C-2 FRC
October 2014 | E. Garate | APS-DPP | Poster
An absolutely-calibrated 12-chord Bremsstrahlung array has been implemented on C-2 and is being used to infer Z-effective profiles and line-averaged values.
