There has been a strong demand for monochromator crystals with a large lattice spacing in order to measure EXAFS spectra at the Mg and Al K‐edges. We have introduced a pair of KTP crystal at BL1A of the UVSOR facility and examined its performance in the energy range between 1200 and 2000 eV. This crystal monochromator can supply stable photon beams enough to measure the EXAFS spectra for the Mg and Al K‐edges. Advantages of the KTP crystal are discussed in comparison with a YB 66 crystal monochromator.
