Abstract

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(66) double-crystal monochromator has been measured by means of a Si PIN photodetector, and X-ray absorption near-edge structure (XANES) of Mg, Al and Si were measured at high resolution. From all of these experiments it has been clarified that a YB(66) double-crystal monochromator is well suited for soft X-ray beamlines on third-generation light sources.

摘要

YB(66)适用于在1-2千电子伏特能量范围内分散同步辐射，其二维晶格间距为1.17纳米。当与波荡器配合使用时，在使用弯铁或摆动器光束线观察到的由YB(66) 400双晶单色仪色散的光谱中，1385.6和1438电子伏特处没有正毛刺。已通过硅PIN光电探测器测量了YB(66)双晶单色仪的传输函数，并在高分辨率下测量了镁、铝和硅的X射线吸收近边结构（XANES）。从所有这些实验中可以明确，YB(66)双晶单色仪非常适合第三代光源上的软X射线光束线。
