PIC SIMULATION OF A NOVEL MICROWAVE OSCILLATOR BASED ON THE SELF-MODULATION OF ANNULAR INTENSE RELATIVISTIC ELECTRON BEAM

摘要：

While an annular intensely relativistic electron beam (IREB) is going through an equi-potential resonant cavity, because of the space-charge effect, static electric field is formed in the cavity, and annular static magnetic field is formed by the IREB itself at the same time. The strong electric field and magnetic field make the electron beam oscillate continuously, which is called self-modulation. Based on this mechanism, the structural design and particle-in-cell (PIC) simulation of a novel microwave oscillator are given. After optimization, 1.7GW microwave output power with a dominant frequency of 4.44GHz can be obtained while a 13.5kA, 1.29MeV electron beam is injected into a 4.5cm long resonant cavity. The efficiency of this oscillator is about 10％.
