Non-existence of positive glitches in spectra using the YB(66) double-crystal monochromator of BL15XU at Spring-8.


YB(66) is suitable for dispersing synchrotron radiation in the 1-2 keV energy range with a 2d lattice spacing of 1.17 nm. When used with an undulator there are no positive glitches at 1385.6 and 1438 eV in spectra dispersed by a YB(66) 400 double-crystal monochromator as observed using bending-magnet or wiggler beamlines. The transmission function of a YB… (More)
