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.

Development of a magnetized coaxial plasma gun for compact toroid injection into the C-2 field-reversed configuration device

Development of a magnetized coaxial plasma gun for compact toroid injection into the C-2 field-reversed configuration device

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

A compact toroid (CT) injector was developed for the C-2 device, primarily for refueling of field- reversed configurations. The CTs are formed by a magnetized coaxial plasma gun (MCPG), which consists of coaxial cylindrical electrodes and a bias coil for creating a magnetic field.
