Description
A passive energy dechirper has been installed on CLARA, a 250 MeV/c electron beam user facility at Daresbury Laboratory. The device, comprising two orthogonal sets of planar dielectric-lined waveguides, is designed to manipulate the longitudinal phase space of the electron bunch, reducing energy spread and thereby delivering higher quality beams for user experiments. We present preliminary results from initial conditioning of the dechirper with the CLARA beam, including measurements of the wakefields excited and changes in longitudinal phase space due to the dechirper. We outline plans for further measurements and discuss how the dechirper will support upcoming user programs.
