EDN: BXVVKZ
Abstract
The concept and design of a relativistic two-cavity reflex klystron with a magnetic mirror is proposed. A 2.5-D computer particle-in-cell (PIC) model of a relativistic two-cavity reflex klystron with magnetic mirror based on the KARAT PIC code was created. The model takes into account the input of an external microwave from the master oscillator, allows self-consistent calculation of the electron dynamics and output characteristic of the klystron. Comparative simulation of relativistic two-cavity reflex klystron with magnetic mirror and relativistic two-cavity transit klystron without magnetic mirror was carried out. It was been shown that the spectral characteristics of both klystrons are close. The output power of the reflex klystron and the transit klystron are compared. It was found that the output power of the reflex klystron is about 1.4 times more that of the transit klystron. The influence of magnetic mirror position on the value of the generated microwave power of the reflex klystron has been studied.
