A computer-vision-based instrument for nanometer accuracy measurement of runout Open
The performance of experiments in a synchrotron beamline depends on the precision of the motion and positioning of multiple components. Motion errors like the runout of rotary stages are often too large for high spatial resolution experime…

Strategies to minimize beam and sample vibration-induced instabilities at the microfocus MX XAIRA beamline at ALBA Open
The performance of microfocus beamlines, and ultimately the quality of the diffraction data, is very sensitive to vibrations affecting the optical elements and the sample stages and holder. We report here the strategies applied in the desi…
