Abstract
Efficiency, scattering, and spectral resolution measurements were made on two equivalent varied-line-spacing plane (VLS) gratings with a central groove density of 1200 1/mm, one a blazed grating made by mechanical ruling and the other holographically recorded and ion etched to a laminar groove profile. The line spacing variation of the holographic grating was obtained by interfering a plane wave and a spherical wave. Both gratings were designed to be used in the monochromator of the Calibration and Standards beamline built and operated by the Center for X-ray Optics at the Advanced Light Source, and all measurements were made efficient in the 600-850 eV region but more efficient below 600 eV and above 850 eV. Substitution of the holographic grating into the beamline extended the energy range from 1000 eV to 1300 eV. The holographic grating exhibited considerably less scattering, but its spectral resolution was lower at an energy of 400 eV. It is likely that this resolution can be improved by adopting a holographic recording system which employs interference of a plane and an aspheric wave.
