Modeling Investigation on a Deflecting-Accelerating Composite RF-cavity System for Phase Space Beam Control
Phase space manipulations between the longitudinal and transverse degrees of freedom hold great promise toward the precise control of electron beams. Transverse-to-longitudinal phase space exchange has been shown to be capable of exchanging the transverse and horizontal emittance or controlling the charge distribution of an electron bunch for beam-driven advanced accelerator methods. The main limitation on the performance of this exchange mechanism stems from the external coupling nature of a realistic deflecting cavity, compared to a thin-lens model. As an extended idea from [A. Zholents, PAC11], this paper presents the design of a composite 3.9-GHz RF system consisting of a deflecting and accelerating-mode cavity. The system design analysis is discussed with particle-in-cell (PIC) simulations of the device performance.
