Beam manipulation in the longitudinal direction is not straightforward due to the speed and duration of the bunch. Longitudinal manipulation usually require dedicated radio-frequency (RF) cavities and anisochronous beamlines (e.g., chicane) to control beam’s time-energy correlation (called chirp). In this talk, a new method using a double emittance exchange (DEEX) beamline was demonstrated for the first time at the Argonne Wakefield Accelerator Facility. It allows control of the longitudinal phase space using relatively simple transverse manipulation techniques. This method enables various longitudinal manipulations such as tunable bunch compression, longitudinal chirp control, and nonlinearity compensation in a remarkably flexible manner. We report proof-of-principle experiment results demonstrating three key functions of the DEEX bunch compressor.
