Development of a three-wave far-infrared laser interferometry and polarimetry diagnostic system for the C-2W field-reversed configuration plasmas

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.

Collisional merging process of field-reversed configuration plasmas in the FAT-CM device

July 2018 | F. Tanaka (Nihon Univ.) | Plasma and Fusion Research | Paper

In order to investigate the collisional merging process of field-reversed configurations (FRCs), the FAT device has recently been upgraded to FAT-CM, consisting of two field-reversed theta-pinch (FRTP) formation sections and the confinement section.

Internal Magnetic Field Measurements of Translated and Merged Field-Reversed Configuration Plasmas in the FAT-CM Device

August 2018 | H. Gota | Review of Scientific Instruments | Paper

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.
