The design of the FURKA RIXS for the SwissFEL is similar to the hRIXS for the European XFEL (see P470) and benefited from the prior development of the hRIXS. The challenge here was to realize the required variable incidence angle on the detector, which is rigidly connected to the detector chamber, without blocking part of the beam and the detector.
The hRIXS for the SCS beamline had to be developed as a mobile instrument regardless of its size and stability requirements to allow for the use of different experimental stations at the beamline. The optical design without beam focusing or collimation in the non-dispersive direction required large diameter bellows between the grating and the detector module and thereby an appropriate…
This soft X-ray diffractometer also serves as a low-temperature sample station for the hRIXS at the SCS beamline at the European XFEL. A triple rotating flange system is integrated into the vacuum chamber allowing for variation of the angle of the scattered radiation from the sample, which is analyzed in the hRIXS. Alignment and sample transfer can be controlled remotely,…
This very compact experimental station was designed for near ambient pressure operation at the SCS beamline of the European XFEL. A short differential pumping unit had to account for a pressure factor of 106. Alignment can be controlled remotely, considering access and space constrains at the installation site.
This grating unit was developed and built to be integrated into the high energy resolution RIXS system at I21-IXS at DLS. The challenge was to accomodate all components for standard functionality and for compensation of spectrometer related spurious movements into a very limited space, without perfomance lost.
