Efficiently heating a magnetically confined plasma to thermonuclear temperatures remains a central issue in fusion energy research. One well-established technique is to inject beams of neutral particles into the plasma, a process known as neutral beam injection.

Development of a three-wave far-infrared laser interferometry and polarimetry diagnostics for the C-2W FRC experiment

Development of a three-wave far-infrared laser interferometry and polarimetry diagnostics for the C-2W FRC experiment

August 2018 | B. Deng | Review of Scientific Instruments | Paper

Great advancements in modern field-reversed configuration (FRC) experiments motivated the development of a 14-chord three-wave far infrared (FIR) laser interferometry and polarimetry diagnostic system, which can provide simultaneous high temporal resolution measurements of density and Faraday rotation profiles with high accuracy.

First experimental measurements of a new fast ion driven micro-burst instability in a field-reversed configuration plasma

In modern F experiments at TAE Technologies, classical FRC instabilities are suppressed
by advanced neutral beam injection and edge biasing methods, leading to high plasma confinement and fast ion pressure built-up which is comparable to the bulk plasma pressure.

Characterization and calibration of the Thomson scattering diagnostic suite for the C-2W field-reversed configuration experiment

Characterization and calibration of the Thomson scattering diagnostic suite for the C-2W field-reversed configuration experiment

October 2018 | A. Ottaviano | Review of Scientific Instruments | Paper

The new C-2W Thomson scattering (TS) diagnostic consists of two individual subsystems for monitoring electron temperature (Te) and density (ne): one system in the central region is currently operational, and the second system is being commissioned to monitor the open field line region.
