The theoretical analysis is carried out within the framework of linearized Vlasov-Maxwell equations. It is assumed that the beam is thin with the radial thickness much smaller than the beam radius. A new and complete dispersion relation for azimuthally symmetric electromagnetic perturbation is derived. In this case, the growth rate of the instability increases but in hollow waveguide decreases due to the increasing self-fields. For both cases the instability band width decreases with the increase in self-fields.
