Abstract: | A class of pulsar models which provide a stationary beam-plasma system as the source of radiation is considered. Since the beam-plasma system is stable near the pulsar where the coherent curvature radiation damps the longitudinal mode, we consider the beam-plasma system away from the star so that the effects of curvature radiation may be neglected. We find that the total wave energy density may attain a significant fraction of the beam energy density provided that the beam and plasma carry away a comparable amount of energy from the star. It should be noted that the attained high wave energy density is peculiar to a relativistic beam-plasma interaction. |
