Interaction simulation of an X-band sheet beam klystron

摘要

In this paper, by means of a 3D particle-in-cell (PIC) code, the non-linear calculation of beam-wave interaction in periodic cusped magnetic (PCM) field is presented for the X-band sheet beam klystron with five three-cell, extended interaction cavities. The simulation results show that the output peak power is more than 32.4 MW, with the interaction efficiency of more than 31.2%, and the gain of more than 35.6 dB.
