| Abstract: | Assuming that the fast ions inject continually into coronal loop, the evolution of the fast ion stream introduced by the ion cyclotron ins ability in coronal loop and the process of the electron acceleration can be studied separately. In this paper, the quantitative expressions for the spectrum and flux of the accelerated electrons induced by the ion cyclotron instability are given in detail. Finally, some characteristics of the acceleration process and their possible applications are discussed. |
