Performance of the YB(66) soft X-ray monochromator crystal at the wiggler beamline of the UVSOR facility.
Soft X-ray spectra have been measured using a pair of YB(66)(400) monochromator crystals at the double-crystal monochromator beamline BL7A of the UVSOR facility, where the wiggler radiation has a magnetic field of 4 T. Deformation of the YB(66) crystal due to heat load from the synchrotron radiation is almost negligible. The photon flux is about 10(8) photons s(-1) (100 mA)(-1) in the energy region 1.2-2 keV and the energy resolution is 0.7 +/- 0.1 eV around hnu = 1.5 keV. These results show that the YB(66) crystal is suitable for use as a monochromator crystal. Its application to soft X-ray spectroscopy is discussed.
