Paper Abstract

The ion-channel laser (ICL), which make use of an electromagnetic instability of an ion-focused relativistic electron beam, is a new form of free-electron laser. In this paper, we introduce a cyclotron electron beam into the ion channel and study the circular polarized ion-channel laser (CPICL) with an axial guiding magnetic field. Using 3D fluid theory, the dispersion relation of the CPICL has been derived. A new kind of radiation mode-ion electrostatic gyro-penitron mode--is found, and the growth rate of this new mode has been obtained for the first time. The effect of axial guiding magnetic field on CPICL is also investigated.
