We investigate the influence of relativistic effects and radiative damping on beam instability. Expressions are obtained for the increment, the effective excitation width of the waves, and the criteria for the occurrence of instability, enabling one to draw a number of new physical conclusions. In particular, in a dense enough plasma the beam instability can be suppressed by radiative damping. We make numerical estimates. For large values of the plasma density and beam energy the effective excitation width of the waves can be so small that excitation of plasma waves becomes practically impossible.
