Two-Dimensional Modeling of a Radially-Convergent Cylindrical Inertial Electrostatic Confinement (Iec) Fusion Device
De-excitation of charge-exchange fast neutrals is estimated as the dominant source of light in Star-mode beams, and electron-impact excitation is estimated as the dominant light source in the Star-mode core. The spatial distribution of these reactions is also in agreement with experimental …
