Abstract :
In this paper the beam transmission of a millimeter wave free-electron laser (FEL) experiment is investigated. The simulation results show a total loss of 34% of the electron beam current in the Group-I orbits regime, which is far smaller than the previous simulations, but no loss of the e-beam current is found in the Group-II orbits regime and the reversed guide magnetic field regime. The influence of the initial transverse velocity of the electron beam on the output power for the reversed guide magnetic field regime is also investigated.
