Chemically selective soft X-ray patterning of polymers

J. Wang, H. D. H. Stöver, A. P. Hitchcock and T. Tyliszczak

Synopsis: A bilayer of two polymers (PMMA/PAN) was successfully patterned at 150 nm spatial resolution in a chemically selective manner by using tuned synchrotron X-rays focused by a Fresnel zone plate in a scanning transmission X-ray microscope.

Diffraction-based automated crystal centering

J. Song, D. Mathew, S. A. Jacob, L. Corbett, P. Moorhead and S. M. Soltis

Synopsis: A fully automated procedure for detecting and centering protein crystals in the X-ray beam of a macromolecular crystallography beamline has been developed. Because the procedure is based on the number of `good' diffraction spots, the best diffracting part of the crystal is aligned to the X-ray beam.

Estimation of soft X-ray and EUV transition radiation power emitted from the MIRRORCLE-type tabletop synchrotron

N. Toyosugi, H. Yamada, D. Minkov, M. Morita, T. Yamaguchi and S. Imai

Synopsis: The total soft X-ray and EUV power which can be emitted by a transition radiation target in the storage rings MIRRORCLE-6X and MIRRORCLE-20SX is estimated. The calculations are performed based on experimental transition radiation data from MIRRORCLE-6X, using optimized one-foil targets, and operating the storage rings at full power.

The effect of CO₂ on the speciation of bromine in low-temperature geological solutions: an XANES study

K. A. Evans, J. Mavrogenes and M. Newville

Synopsis: Br in fluid-inclusion-hosted CO₂-bearing solutions exhibits a pre-edge peak not found in CO₂-free Br-bearing solutions. The peak is attributed to the effects of CO₂ on the hydration and hence the charge density of Br^- ions in solution.

Submicrometer hard X-ray focusing using a single-bounce ellipsoidal capillary combined with a Fresnel zone plate

A. Snigirev, A. Bjeoumikhov, A. Erko, I. Snigireva, M. Grigoriev, V. Yunkin, M. Erko and S. Bjeoumikhova

Synopsis: A two-step focusing set-up combining a Fresnel zone plate with an ellipsoidal capillary is presented. An X-ray beam with 15 keV energy was focused down to 250 nm, demonstrating the best spot size that has been achieved up to now for single-bounce capillaries.
