TL;DR: A new facility for microdiffraction strain measurements and microfluorescence mapping has been built at the advanced light source of the Lawrence Berkeley National Laboratory and allows a variety of experiments, which have in common the need of spatial resolution.
Journal ArticleDOI
Images of the Antiferromagnetic Structure of a NiO(100) Surface by Means of X-Ray Magnetic Linear Dichroism Spectromicroscopy
Joachim Stöhr,Andreas Scholl,T. J. Regan,Simone Anders,Jan Lüning,M. R. Scheinfein,Howard A. Padmore,Robert L. White +7 more
TL;DR: In this article, the first images of a surface showing clear antiferromagnetic contrast were obtained for 1080thinspthinpnm thick NiO(100) films grown on Mg(100), by means of x-ray magnetic linear dichroism spectroscopy in conjunction with high resolution photoelectron emission microscopy.
Journal ArticleDOI
A beamline for high-pressure studies at the advanced light source with a superconducting bending magnet as the source

Gleason,James Glossinger,Nicholas Kelez,D. Plate,Tony Yu,Joeseph M. Zaug,Howard A. Padmore,Raymond Jeanloz,A. Paul Alivisatos,Simon M. Clark +18 more
TL;DR: A new facility for high-pressure diffraction and spectroscopy using diamond anvil high- pressure cells has been built at the Advanced Light Source and the experimental enclosure contains an automated beam-positioning system, a set of slits, ion chambers, the sample positioning goniometry and area detector.
Journal ArticleDOI
A new bend-magnet beamline for scanning transmission X-ray microscopy at the Advanced Light Source
Tony Warwick,Harald Ade,A. L. David Kilcoyne,Michael Kritscher,Tolek Tylisczcak,Sirine C. Fakra,Adam P. Hitchcock,Peter Hitchcock,Howard A. Padmore +8 more
TL;DR: This is the first diffraction-limited scanning X-ray microscope to operate with a useful count rate on a synchrotron bend-magnet source and it provides radiation for C 1s, N 1s and O 1s near-edge X- Ray absorption spectromicroscopy with STXM count rates in excess of 1 MHz and with spectral resolution typically 1:2000.
Journal ArticleDOI

TL;DR: The inversion of a diffraction pattern offers aberration-free diffraction-limited 3D images without the resolution and depth-of-field limitations of lens-based tomographic systems, the only limitation being radiation damage.
