A uniform density (n̂b) relativistic nonneutral electron beam with radius Rb propagates parallel to a uniform magnetic guide field B0êz. The current density is assumed to be uniform with J0bz(r)=−n̂beβbc=const within the beam (0<r<Rb). The spontaneous emission from a test electron is calculated for emission in the forward direction (along êz ) including the important influence of equilibrium radial self-electric and azimuthal self-magnetic fields. For an electron beam with νb/γb≪1 (here, νb is Budker’s parameter, and γbmc2=const is the characteristic electron energy), it is found that the spontaneous emission spectrum is peaked for oscillation frequency (ω) and wavenumber (k) satisfying the resonance conditions ω−kvz= ω−≡(ωcb/2) ×[1−(1−s)1/2] and ω−kvz≡ω+≡(ωcb/2)[1+(1−s)1/2], where s=(2ω2pb/ω2cb)(1−βzβb) is the self-field parameter. Here, vz=βzc is the axial electron velocity, ωcb=eB0/γbmc is the electron cyclotron frequency, and ω2pb=4πn̂be2/γbm is the electron plasma frequency-squared. Finally, an applied helical wiggler field δB=δB(cos k0zêx+sin k0zêy) is added to the field configuration, and the influence of equilibrium self-fields on the wiggler-induced spontaneous emission in the forward direction is calculated for emission near the free-electron-laser resonance condition ω−kvz=k0vz.
