Self-consistent theory of cyclotron maser instability for intense hollow electron beams

Technical Report ·
OSTI ID:5583712

This paper develops a self-consistent theory of the cyclotron maser instability, assuming azimuthally symmetric perturbations about a slowly rotating hollow electron beam propagating parallel to a uniform axial magnetic field (B sub 0) (e sub z). The stability analysis is carried out within the framework of the linearized Vlasov-Maxwell equations. The analysis is carried out for the specific choice of equilibrium electron distribution function in which all electrons have the same value of canonical angular momentum and the same value of energy in a frame of reference moving with axial velocity c(beta sub b). Stability properties are investigated including the important influence of finite radial geometry, finite beam temperature, and transverse magnetic perturbations.
