Experiment for Evaluating a K -Band Space TWT Electron Beam
IEEE Transactions on Electron Devices(2021)
Abstract
The electron beam of a ${K}$ -band space traveling-wave tube (TWT) has been investigated in a beam measurement system in this article. The primary beam emitted from a Pierce-type electron gun is scanned by a Faraday cup probe, and the beam current density distribution and envelope are determined. The spent beam is also diagnosed with a novel retarding field energy analyzer (RFEA) by using the mon...
