Design and Simulation Beam-Wave Interactions of 263GHz Extended Interaction Klystron For Dynamic Nuclear Polarization
2023 Cross Strait Radio Science and Wireless Technology Conference (CSRSWTC)(2023)
摘要
The 263 GHz extended interaction klystron (EIK) based on “Pre-Bunch”(PB) cavity structure is proposed in this paper. Compared with the conventional EIK design, the PB-cavity structured EIK has higher electron interaction efficiency. The results of 3-D particle-in-cell (PIC) simulation shows that with the voltage and the current are 22.56kV and 0.15A, respectively the output power is over 32 W and 3dB bandwidth is 320MHz.
