Abstract

This paper presents the design and the measurement of a short section of a 36 GHz microwave undulator, as well as the electron beam dynamic and the spectrum of the FEL radiation based on the microwave undulator. The operation of the microwave undulator at a higher frequency of 94 GHz is also discussed.
