Figure 2
hRIXS spectrometer grating efficiency. Lines represent the computed values at four incidence angles with Au coating, aspect ratios c/d = 0.60 and 0.65, and groove depths h = 5 nm and 9 nm for the high-resolution grating (HRG) and high-transmission grating (HTG), respectively (Schäfers & Krumrey, 1996). The measured values for the HTG are shown by symbols (measurement performed at PM1 at BESSY II). |
