Optical layout of the BM26A beamline at ESRF. The optical elements are an (optional) collimating mirror, a double-crystal sagittal focusing monochromator and a vertically focusing mirror. Both mirrors have a strip with a bare silicon surface as well as a strip with a Pt coating. Depending on the energy range and the requirement for higher harmonic rejection, one of the strips can be brought into the beam by a sideways translation. |
