Description

RUEDI is a proposed relativistic ultrafast electron diffraction and imaging facility. It will have two beamlines: a diffraction beamline and an imaging beamline. This proceeding discusses the beam dynamics design of the diffraction beamline. The diffraction beamline needs to have the best temporal resolution possible which requires short bunch length and minimal time of arrival jitter at the sample. To achieve this a magnetic bunch compressor operated in a jitter cancelling configuration is used. To achieve compression as well as jitter cancellation the beam’s longitudinal space charge forces are used to modify the chirp to compress the beam. The RUEDI diffraction line will operate at 4 MeV meaning that both space charge forces and ballistic effects are significant and need to be accounted for in the design. The diffraction line will be operated in three modes: single-shot, stroboscopic and streaking.
