A plasma is characterized by a large ratio of gyrofrequency, omega x beta, to plasma frequency, omega sub zero, in order to provide a foundation for the evaluation of recent theoretical models of pulsars. The model is a cold electron-positron plasma of density 2n sub 0 in a strong uniform magnetic field, through which a low density, monoenergetic relativistic beam of energy streams along the field. The collective mode structure of the cold plasma is analyzed. Linearly polarized modes are eigenoscillations for parallel propagation, and there is a purely transverse, linearly polarized mode whose properties are independent of the angle of propagation. The Cerenkov and cyclotron beam-plasma instabilities are investigated analytically for all angles of propagation. Instabilities occur in two frequency bands; at low frequencies (omega less than or equal to nu sub 2 x omega sub zero) and at high frequencies (omega approx. equal to omega x beta).
