ABSTRACT
Describes a Thomson parabola spectrograph that utilizes an electric field parallel to a magnetic field and a two-dimensional imaging detector to uniquely identify the energy-per-charge and mass-per-charge distributions of plasma ions. Characteristics of the spectrograph; Removal of deviations of observed spectra; Applicability of the spectrograph for neutral atom identification.

    The analysis of plasma beam and shear problems in magnetic fields is usually based on a hydromagnetic fluid model. In a low-density collisionless plasma, however, the kinetic effects of the plasma, such as finite Larmor radius effects, are not yet clearly understood. In this paper, the kinetic...
