Emittance Exchange Based Bunch Compression at Argonne Wakefield Accelerator Facility

An emittance exchange (EEX) beamline can manipulate longitudinal phase space via control of the transverse one at the entrance to the beamline. This EEX beamline can compress a bunch length to a sub-fs level when a specific transverse focusing is applied to the small beam at the entrance of the beamline. The Argonne Wakefield Accelerator Facility (AWA) plans to generate the sub-fs bunch for applications to wakefield accelerators. A preliminary experiment has been performed using the existing EEX beamline at AWA. In this poster, results of the experiment and feasibility of sub-fs bunch compression with a modified EEX beamline are presented.
