PIC Simulation of a double side-cavity reltron, calculation of cavity reactance and comparison with conventional reltron

Abstract

A double side-cavity reltron is proposed and simulated using CST particle studio which predicts ∼20 % increase in the pulse duration than a conventional reltron. A comparison of the beam wave interaction study and the cavity reactance in the first three normal modes (0, π/2 and π) among the conventional reltron and the double side-cavity reltron is also presented. The inductance and capacitance are calculated from loaded quality factor (Ql), by assuming the tank circuit equivalent model of a cavity resonator. The frequency domain solver of CST microwave studio is used to find the Ql of the cavity from normalized S11 © 2019 IEEE.
