Impact of FBG array embedded on/in helix support rods on TWT performance

Abstract

In order to obtain the temperature distribution along inner helix of working TWTs, fiber Bragg grating array (FBGA) can be considered to be used in testing the temperature. Two testing methods based on FBGA embedded on/in support rod helix structure are proposed. The influence of the FBGA on beam-wave interaction is analyzed through CST. The results show… (More)
