A brief description of the monochromator built in-house for the SEXAFS and X-Ray Standing Wave beamline of ESRF is given. The monochromator covers the energy range 2-40 keV with two sets of diffracting crystals and has provisions for adding a third pair. The two first crystals are ciyogenically cooled and the second ones can be sagittally bent. The height of the beam at the mirror position 11.5 m- downstream is inherently almost fixed during energy scans and can be pinned to the sample slits by simply controlling the pitch of the second crystals.
