Field-reversed configuration (FRC) Amplification via Translation–Collisional Merging (FAT-CM) experiments have recently commenced to study physics phenomena of colliding and merged FRC plasma states.

Calibration and applications of visible imaging cameras on the C-2U advanced beam-driven field-reversed configuration device

August 2018 | E. M. Granstedt | Review of Scientific Instruments | Paper

Two filtered, fast-imaging instruments, with radial and axial views, respectively, were used on the C-2U device to visualize line emission from impurities and hydrogenic neutrals.

Magnetic diagnostic suite of the C-2W field-reversed configuration experiment

July 2018 | T. Roche | Review of Scientific Instruments | Paper

A fundamental component of any magnetically confined fusion experiment is a firm understanding of the magnetic field. The increased complexity of the C-2W machine warrants an equally enhanced diagnostic capability.

Measuring dynamic fast ion spatial profiles with fusion protons in the Madison Symmetric Torus

July 2018 | R. M. Magee | Review of Scientific Instruments | Paper

Neutral beam injected fast ions play a dominant role in both the field reversed configuration (FRC) at TAE Technologies and the Madison Symmetric Torus (MST) reversed field pinch (RFP), making fast ion diagnosis a major pillar of both research programs.

Performance Improvement of a Magnetized Coaxial Plasma Gun by adopting Iron-Core Bias Coil and Pre-Ionization Systems

March 2018 | T. Edo | Plasma and Fusion Research | Paper

A magnetized coaxial plasma gun (MCPG) is utilized to generate a compact toroid (CT). An MCPG-type CT injector had been developed as a particle refueling system for C-2/C-2U field-reversed configuration (FRC) plasmas. To inject CTs repetitively for a long-lived plasma, the injector has been upgraded.
