文摘Electron motion in the combined ion-channel,helical wiggler and axial magnetic fields is analyzed in the absence of a radiation field.Detailed analysis of the gain equation in a free-electron laser is presented.Numerical calculations are made to illustrate the effects of the two electron-beam guiding devices on the gain when applied separately and simultaneously.
