When the angle radius of the diffraction spot's the first dark ring is big, the effect is relatively small. But when the angle radius is small, especially for turbulent effects being weak, the effect on the beam spreading is very distinct, and the magnitude of the beam spreading is mainly dependent on the jitter item of the scaling relations.

The results show that:(1) The space-charge fields(include dc space-charge fields and ac space-charge fields) have important effect on the beam-wave interaction output power, make the saturated output power lower, saturated position delay;(2) The back-radio excited by the electron beam has little effect on the output power, and can be ignored;(3) The transverse motions of electron beam has some effect of the output power;(4) The means of phase velocity taped and bunch compression can improve the relativistic TWT efficiency, especially bunch compression can greatly improve the efficiency.
