Description
SwissFEL, like other SASE-based x-ray FEL facilities, requires the monitoring of the photon spectrum (photon energy and intensity) on a shot-to-shot basis for machine optimization and for experiments. In order to cover the Hard X-ray range variations (4-15keV) for the Aramis beamline, the Photon Single Shot Spectrometer has been designed to measure the spectrum with high resolution over the bandwidth of the SASE FEL beams. Additionally, a new idea and first results of a proof-of-principle experiment for an online device in Tender X-ray regime (2-4keV) will be shown and discussed. The concept is based on dispersive von-Hamos geometry composed with a scattering sample to look at the elastic scattering spectrum.
