Description
In the past year, a UCLA-NIU-ANL-LANL-SLAC collaboration has begun a dedicated experimental program investigating a technique to produce microbunching and associated coherent radiation by manipulating electron beams using the emittance exchange (EEX) beamline at the Argonne Wakefield Accelerator (AWA). This type of scheme, while awaiting first tests of its efficacy, underpins the ambitious compact short wavelength FEL program at ASU, the CXFEL project. The goal of this study is to experimentally determine the practical limits to create longitudinally pre-modulated electron beams, subject to collective effects such as space-charge and coherent synchrotron radiation. We give here an overview of the experimental setup, including beam optics layout, beam diagnostics, coherent radiation diagnostics. We review simulation and theoretical modeling issues, and discuss hardware development and near term run plans.
