Description
RUEDI (Relativistic Ultrafast Diffraction and Imaging) is a planned UK national user facility. It has a diffraction beamline optimised for temporal resolution. This beamline uses an S-band normal conducting RF gun followed by a triple bend achromat magnetic compressor which simultaneously compresses the bunch and suppresses the time of arrival jitter to the 10 fs scale. The compressor has variable R56, sextupoles for control of T566 and optics designed to mitigate space charge degradation of the electron beam quality. After the sample the diffraction patterns are magnified onto the detector using flexible variable camera length solenoid optics.
