Investigation of a short-period microwave undulator

A cavity-type microwave undulator (MU) based on a corrugated cavity operating at 36 GHz was designed. A short-corrugated section prototype was manufactured and measured to validate the resonance frequency and quality factor. The electron beam trajectory in the MU with a full length of 1-meter was simulated to exam the electron drift distance in the radial direction. The radiation spectrum from the MU shows soft X-ray radiation can be produced with 250 MeV electron bunches.
