The crystallography stations at the Alba synchrotron

摘要: Alba is a 3rd-generation 3 GeV synchrotron facility with an emittance of 4.6nm·rad which has been operational since 2011 and recently started top-up operation. Photons in broad energy range 0.08-80 keV are served to seven beamlines dedicated large variety scientific fields. The portfolio includes two beamlines, XALOC MSPD, fully X-ray crystallography. BL13-XALOC currently the only macromolecular crystallography beamline. end-station high-accuracy single-axis diffractometer removable minikappa stage, sample-mounting robot large-area, photon-counting detector. beamline optics, fed by in-vacuum undulator, deliver tunable photon beam between 5.5 22 keV. size at sample position can be adjusted defocusing mirrors 50-300μm horizontal direction 5.5-300μm vertical direction. Beamline BL04-MSPD, superconducting wiggler, in-line end-stations. first station devoted high-pressure/microdiffraction. It offers \( 15\times 15\) μm 20-50 keV, particularly suited for powder diffraction studies requiring very small beam, e.g. mapping cultural heritage samples high-pressures studies. second high-resolution/high-throughput diffraction. covers 8-50 heavy-duty 3-circle equipped 13-channel multianalyzer detector high-angular resolution ( \Delta 2\theta=0.004^{\circ}\) FWHM) high-throughput, position-sensitive spanning 40^{\circ}\) 2\( \theta\) allowing millisecond data acquisitions.
