Gerwin, R A

A cylindrical plasma was assumed in an infiritely strong axial magnetic field. Taking only longitudinal temperature into account, a dispersion relation (including Landau damping) was calculated for electron charge oscillations whose wavelengths are much larger than the plasma radius. The Landau damping was found to be far larger than that of waves in an infinite plasma of the same density and temperature, and for the same wavelength. The radiation damping of these oscillations was also calculated. It was found that these oscillations do not radiate at all from an infinitely long cylinder. For a plasma cylinder of finite length it was found that the radiation damping of these oscillations can be made negligible compared to Landau damping for reasonable laboratory parameters. It was assumed throughout that the unperturbed state is a Maxwellian velocity distribution. (auth)
