Absence of Ion-scale Core Turbulence

Absence of Ion-scale Core Turbulence and Transport Barrier Formation with Passive/Active Divertor Biasing in the C-2/C-2U Field Reversed Configuration

October 2016 | APS-DPP | Poster

Experimentally measured inverted core density fluctuations spectra show the absence of ion-scale modes in the FRC core, in agreement with linear, local gyrokinetic simulations.

Improved Confinement of C-2 Field Reversed Configuration Plasmas

February 2015 | Fusion Science and Technology | Paper

C-2 is a unique, large compact-toroid (CT) device at Tri Alpha Energy 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.

Overview of C-2 field-reversed configuration experiment plasma diagnostics

August 2014 | Review of Scientific Instruments | Paper

A comprehensive diagnostic suite for field-reversed configuration (FRC) plasmas has been developed and installed on the C-2 device at Tri Alpha Energy to investigate the dynamics of FRC formation as well as to understand key FRC physics properties, e.g., confinement and stability, throughout a discharge.
