Abstract
An instrument is described to perform laser-scattering fundamental
studies on an analytical planar-cathode glow discharge. Electron
properties such as electron number-density, electron temperature and the
shape of the electron energy distribution function were successfully
obtained via Thomson scattering. It is observed that several groups of
electrons contribute to the Thomson scattering spectrum and the
existence of a non-Maxwellian electron energy distribution was
confirmed. The measured temperature for slow electrons is comparable to
that found in previous studies performed with alternative methods. In
addition, Rayleigh scattering was used to acquire argon gas-kinetic
temperatures. The performance of the instrument as well as the
significance of the results will be discussed.
