BL13-XALOC is currently the only macromolecular crystallography beamline at 3 GeV ALBA synchrotron near Barcelona, Spain. The optics design based on an in-vacuum undulator, a Si(111) channel-cut crystal monochromator and pair of KB mirrors. It allows three main operation modes: focused configuration, where both mirrors can focus beam sample position to 52 µm × 5.5 FWHM (H V); defocused configuration that match size dimensions crystals or detector; unfocused one are removed from photon path....

We present an adaptive mirror system capable of controlling the figure surface with resolution and stability below one nanometer, in operation conditions. This allows correcting wavefront deformations caused by static or dynamic sources, like thermal bump on optics, gravity sag, clamping effects, to level highest quality errors. The bender includes usual torque actuators at ends as well a number force correctors along length, which introduce desired deformation substrate. substrate is...
The ALBA synchrotron (Barcelona, Spain) is building MINERVA a new X-ray beamline designed to support the development of ATHENA mission (Advanced Telescope for High Energy Astrophysics). design originally based on monochromatic pencil beam XPBF 2.0 at Physikalisch-Technische Bundesanstalt (PTB), BESSY II. will provide metrology capabilities integrate stacks produced by cosine company into mirror module (MM) and characterize them. It photons with fixed energy 1.0 keV residual divergence below...
The XALOC beamline is dedicated to macromolecular crystallography. position and angle of the X-ray beam at sample change in horizontal vertical directions.
