Abstract

We demonstrate a water-window condenser arrangement for transmission x-ray microscopy based on table-top sources. A spherical normal-incidence multilayer mirror is used to focus and monochromatize water-window x-ray emission from a high-brightness droplet-target laser-plasma source. The condenser arrangement is compact, has high collection efficiency, and is easy to align. The maximum normal- incidence reflectivity at the desired wavelength, (lambda) equals 3.37 nm, was determined to be up to 3 percent. The potential for compact water-window transmission x-ray microscopy using the condenser arrangement is discussed.
