Next-generation X-ray Optics for High Resolution Applications

Optics for coherent X-ray applications

Developments of X-ray optics for full utilization of diffraction-limited storage rings (DLSRs) are presented. The expected performance of DLSRs is introduced using the design parameters of SPring-8 II. To develop optical elements applicable to manipulation of coherent X-rays, advanced technologies on precise processing and metrology were invented. With propagation-based coherent X-rays at the 1...

Beam collimation with polycapillary x-ray optics for high contrast high resolution monochromatic imaging.

Monochromatic imaging can provide better contrast and resolution than conventional broadband radiography. In broadband systems, low energy photons do not contribute to the image, but are merely absorbed, while high energy photons produce scattering that degrades the image. By tuning to the optimal energy, one can eliminate undesirable lower and higher energies. Monochromatization is achieved by...

Next Generation Adaptive Optics

INTRODUCTION 3 This document discusses considerations for the DAVINCI instrument’s pupil image quality and pupil mask selections. The DAVINCI instrument (Adkins et al., 2010) requires a cold pupil mask to control background, especially in the near-IR wavelengths. Different size masks may be required to balance throughput loss and background suppression, with additional masks required for the DA...

Next-generation Polymers for High Power Uv Replicated Optics

Ultra-high resolution zone-doubled diffractive X-ray optics for the multi-keV regime.

X-ray microscopy based on Fresnel zone plates is a powerful technique for sub-100 nm resolution imaging of biological and inorganic materials. Here, we report on the modeling, fabrication and characterization of zone-doubled Fresnel zone plates for the multi-keV regime (4-12 keV). We demonstrate unprecedented spatial resolution by resolving 15 nm lines and spaces in scanning transmission X-ray ...
