A zone-plate X-ray microscope.

Laboratory arrangement for soft x-ray zone plate efficiency measurements.

We demonstrate a laboratory-scale arrangement for rapid and accurate measurements of the absolute and local efficiency of soft x-ray micro zone plates in the water window. This in-house instrument is based on a single-line lambda = 2.88 nm liquid-jet laser-plasma source. Measurements are performed by a simultaneous comparison of first diffraction-order photon flux with the flux in a calibrated ...

Towards 10-nm Soft X-Ray Zone Plate Fabrication

In this paper the latest efforts to improve our nanofabrication process for soft x-ray zone plates is presented. The resolving power, which is proportional to the smallest outermost zone width of the zone plate, is increased by introducing cold development of the electron beam resist that is used for the patterning. With this process we have fabricated Ni zone plates with 13-nm outermost zone a...

A High-resolution X-ray Microscope

92 LLE Review, Volume 74 A soft x-ray microscope (E & 3 keV) with high spatial resolution (~3 μm) has been characterized at LLE and used for initial experiments on the OMEGA laser system to study the hydrodynamic stability of directly driven planar foils. The microscope, which is an optimized Kirkpatrick-Baez (KB)–type design, is used to obtain four x-ray radiographs of laser-driven foils. Time...

A Framed Monochromatic X-ray Microscope

Detector Crystal The Laser Fusion Experiments Groups from the Laboratory for Laser Energetics (LLE) and the Los Alamos National Laboratory (LANL) have jointly developed an instrument capable of simultaneously space-, time-, and spectrally resolving x-ray emission from inertial confinement fusion (ICF) targets. Uses of the instrument include framed imaging of line emission from fuel or shell dop...
