Theoretical design and simulation of three transmission lines based on TPG2000

The scheme of three spiral transmission lines is presented, according to the concept that multiple electron beams produced by single pulsed power generator drive multiple HPM sources. Since the three pulses output by the scheme are produced by single main pulse, their time synchronization accuracy is high. Based on the Tesla-type pulsed power generator TPG2000, design results of three transmission lines are presented by theoretical simulation. Through simulation of pulse transmission process and optimization of structure, three pulses of the same parameters are obtained, and two of them have a 20 ns delay compared with the other one.
