摘要：

An X-band klystron-like relativistic backward wave oscillator (RBWO) has been designed and studied for its efficiency enhancement by implementing triple extraction and dual modulation cavities. The proposed dual modulation cavities klystron-like RBWO have been modeled in a finite-difference time-domain (FDTD)-based particle-in-cell (PIC) code to illustrate its beam-wave interaction behavior and to study the effect upon the fundamental harmonic current and growth of axial electric field. The PIC simulation of klystron-like RBWO operating at the magnetic field of similar to 2.9 T predicted an RF output power similar to 2.79 GW with operating frequency similar to 9.5 GHz and the power conversion efficiency similar to 73% without the shortening of the pulse up to similar to 300 ns of simulation time.
