A double crystal X-ray monochromator for the SpLine diffraction and absorption synchrotron bending magnet beamline at the ESRF

The CRG BM25-SpLine Beamline is located at bending magnet 25 of the ESRF. The beamline, which is split in two branches, is devoted to XAS, XRD and HAXPES. The photon energy covered by both branches range between 5 and 45 keV. The beamline double crystal monochromator (DCM) uses two parallel Si(111)...

Description
Summary:The CRG BM25-SpLine Beamline is located at bending magnet 25 of the ESRF. The beamline, which is split in two branches, is devoted to XAS, XRD and HAXPES. The photon energy covered by both branches range between 5 and 45 keV. The beamline double crystal monochromator (DCM) uses two parallel Si(111) crystals in (+, −) configuration to produce a monochromatic exit beam parallel to the incident white X-ray beam. It accepts 2mrad of radiation from the bending magnet. The DCM has been recently upgraded. Several special features concerning the cooling of the first crystal, second crystal positioning and sagittal focusing mechanism has been improved. In this work a detailed description of the performed modifications is presented.
