Designed through research of electron beam transmission characteristic in different coupled cavity structures, long periodic permanent magnetic focusing system solves problems of factors influencing electron trajectories such as transverse magnetic field, open magnetic ring and magnetic field in transition region. 3D program simulation of electron optics system for X-band coupled cavity traveling wave tube shows 100% transfer efficiency of electron beam and 9% ripple of electron beam, which accords with requirements of coupled cavity traveling wave tube experiment.
