Description
An emittance exchange (EEX) beamline may provide a unique capability in transferring a transverse beam density modulation into longitudinal bunching. This process can be advantageous for generating coherent radiation below the micron level, through super-radiant emission in a radiating system, or by providing a large input signal for a high gain FEL. Indeed, this mechanism has been proposed to enable FEL action down to the few nm scale for a future facility now under construction at ASU. We investigate the feasibility of creating longitudinal density modulation at the Argonne Wakefield Accelerator, beginning with 800 nm bunching in a pC-level beam. We discuss plans for modulated beam creation, also addressing collective and nonlinear effects in the EEX beamline and subsequent radiation-based diagnosis via CTR or FEL processes.
