Characterization of compact-toroid injection during formation, translation, and field-penetration

July 2016 | T. Matsumoto | Review of Scientific Instruments | Paper

We have developed a compact toroid (CT) injector system for particle refueling of the advanced beam- driven C-2U field-reversed configuration (FRC) plasma. The CT injector is a magnetized coaxial plasma gun (MCPG), and the produced CT must cross the perpendicular magnetic field surrounding the FRC for the refueling of C-2U.

A mass resolved, high resolution neutral particle analyzer for C-2U

July 2016 | Ryan Clary | Review of Scientific Instruments | Paper

C-2U is a high-confinement, advanced beam driven field-reversed configuration plasma experiment which sustains the configuration for >5 ms, in excess of typical MHD and fast particle instability times, as well as fast particle slowing down times.

Innovative high-gain optically pumped far-infrared laser

July 2016 | B. Deng | Applied Optics | Paper

A new optically pumped far-infrared (FIR) laser with separate pump beam reflector and FIR output coupler has been developed. The new design greatly simplifies the tuning of the laser and enables the optimization of the pump beam absorption without affecting the laser alignment.
