Tracking Analysis of a Sheet Electron Beam for Clinotron Tube

Effective operation of a clinotron, as well as any other Cherenkov electron vacuum device, critically depends on electron beam formation quality and velocity spreads. Main results, related with an electron gun analysis and electron beam formation for a clinotron are presented in this paper. To study the longitudinal velocity spreads, the sheet electron beam has been investigated by means of 3D particle tracking simulations. Verification of obtained results was carried out by simulation in CST Particle Studio.
