Kaznacheyev, KV; Karunakaran, C; He, F; Siegrist, M; Summers, T; Obst, M; Hitchcock, AP: CLS ID-10 chicane configuration: From “Simple Sharing” to extended performance with high-speed polarization switching, Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 582(1), 103-106 (2007), online: 2009-08-12, doi:10.1016/j.nima.2007.08.082 [Link]
Abstract:

The chicane scheme adopted for the elliptically polarized undulators (EPU) in the ID10 section at the Canadian Light Source (CLS) not only permits independent operation of two beamlines, but also allows to redirect beams from two EPUs into a single beamline with a performance similar to a “dedicated” configuration. Fast switching at kHz rates will be achieved by piezo shutters located after exit slits which will block the light of alternate polarization.
