Abstract

Abstract

Properties of coherent radiation of millimeter wave generated by a intense rotating annular relativistic electron beam (E-layer) which is from a cusp magnetic field are investigated. The linearized Vlasov-Maxwell equations are used to analyze the interaction between E-layer and re-sonnator of magnetron. The dispersion relation is deduced and numerical calculation is made. The results show that the frequency of microwave radiation is r(r = l∥ where ∥ is the electron relativistic cyclotron frequency in the axial magnetic field; l is the aximuthal mode number, l=n+mN; N is the number of side resonnators, n=0, 1, 2, N/2, m is any integer). The growth rate of radiation is still large enough even if l is good for generating millimeter wave radiation at low axial magnetic field. If the modes can be controlled well, a tunable, high power millimeter wave device can be made.
