Design of a Deflecting Cavity with a Racetrack Cell

We designed a new deflecting cavity to verify the longitudinal characteristics of a 10-GeV electron beam. The new deflecting cavity is operated in the 2π/3 mode at 11.424 GHz. A regular cell with a racetrack shape is proposed to separate the parasitic mode. In this paper, we will compare the RF characteristics of the newly proposed type of cavity and to those of previous types of deflecting cavities, such as the LOLA cavity and the pocket cell cavity.
