At synchrotron radiation facilities vibration is often a problem causing poor quality of photon beams. At the Canadian Light Source (CLS) Hard X-ray MicroAnalysis (HXMA) beamline, the MicroProbe endstation is particularly sensitive to vibrations since very small beam size (∼ 3μm × 5μm) is required. Thus, a measurement system is desired to investigate vibrations of the X-ray beam at HXMA beamline. This paper presents a design of such a X-ray beam vibration measurement system. The system consists of two sub-systems: (a) measurement system and (b) vibration-isolation platform. Mathematical models are developed and detailed design is conducted. The design is numerically investigated and it shows very promising results.
Vibration is often a problem causing poor quality of photon beams at synchrotron radiation facilities, since beamlines are quite sensitive to vibrations. Therefore, vibration analysis and control at synchrotron radiation facilities is crucial. This paper presents investigations on mechanical vibrations at four beamlines and endstations at the Canadian Light Source, i.e. the Canadian Macromolecular Crystallography Facility 08ID-1 beamline, the Hard X-ray MicroAnalysis 06ID-1 beamline, the Resonant Elastic and Inelastic Soft X-ray Scattering 10ID-2 beamline, and the Scanning Transmission X-ray Microscope endstation at the Spectromicroscopy 10ID-1 beamline. This study identifies vibration sources and investigates the influence of mechanical vibrations on beamline performance. The results show that vibrations caused by movable mechanical equipment significantly affect the data acquired from beamlines.
