The main principle of Relativistic Two-Stream Amplifier (RTSA) is the two-stream interaction mechanism. This two-stream interaction mechanism generates the two-stream instability. In the R TSA, there are two concentric circular beams and they propagate through the wave guide in the same direction. The energy exchanging is between the inner beam and outer beam, and the output power of microwave at the end cavity (output cavity) of RTSA is only pumped from the outer electron beam. The effect of inner beam supports the two-stream instability. And for a high power signal, the linear theory does not fit and the nonlinear theory is adopted. Using the MA GIC PIC simulation program, the author simulated the S-band RTSA, studied the two-stream interaction mechanism and deeply understood the two-str
