Dual cavity arletron

Abstract

In dual cavity arletron, we put an extra modulation cavity just after the first modulation cavity to enhance the beam current modulation. This dual modulation cavity with the post-acceleration voltage allows creating a very dense electron bunches. The dual cavity arletron has been designed with the CST Microwave Studios. The hot (particle-in-cell) simulation has been carried out and a simulation result predicts that the device is capable to generate a microwave peak power of 950MW, which is 250 MW greater than the reported single cavity arletron. The total output of microwave power yielding a power gain of 1.38. © 2019 IEEE.
