Abstract

This paper describes a new method for improved determination of multilayer period using a soft x-ray reflectometer based on a line-emitting high-brightness water-window liquid-jet laser- plasma source. The use of line emission with well-known wavelengths allows accurate measurements of multilayer period without source monochromatization and calibration. By using a new multi-line data analysis procedure the multilayer period of W/B₄C mirrors can be determined with an accuracy of 0.001 nm.
