Soft X-ray source based on the high-current capillary-discharge system

Abstract

This paper reports on the experimental results of interaction of focused XUV laser beam (wavelength 46.9 nm) with Polymethylmethacrylate (PMMA) sample. Laser-beam footprints in the region near the tangential focus of spherical mirror with/without multi-layer reflecting coating are presented and discussed.

Reflection coefficients of these two spherical mirrors are published as well.
