| 内容記述 | Experimental studies have been performed to evaluate the enhancement of diffraction efficiency of diffraction gratings by overcoating with lanthanum series layers on conventional metal coated laminar-type gratings around B-K emission (6.76 nm, 184 eV) spectrum. In the previous study we observed this effect with a laminar-type Ni-coated diffraction grating overcoated with diamond-like carbon (DLC), TiO2, and CeO2 layers which have high reflectivity and small extinction coefficient. In this study, LaF3 and La/C layers were overcoated on Ni-coated gratings, and diffraction efficiency was measured by use of the reflectometer at the PF-BL11D beamline. As the results, the enhancements of spectral flux at 6.76 nm are 3.62 and 4.41 times at the incident angles of 85.005° and 85.050° for LaF3 and La/C overcoated gratings, respectively, compared with that of a conventional Ni coated grating used at an incidence angle of 87.070°. | |||||
