Abstract

Reflective optics operated at grazing angle of incidence has a good polarization transfer function and was preferred to focus or steer the X-ray beam on the ESRF beamline ID12A which is dedicated to X-ray dichroism. The present paper reports on the design of a double mirror device (VF-2M) that is located downstream with respect to the monochromator and can refocus the X-ray beam vertically very near the sample location. This system combines two identical mirrors (L equals 600 mm; W equals 40 mm; T equals 12 mm) made of bulk CVD-SiC which were polished to a very precise cylindrical shape: when no bending forces are applied, each mirror has a concave curvature radius of 1 km with a slope error
