34ID-E is an [[wikipedia:undulator | undulator]] [[wikipedia:Beamline#Synchrotron_radiation_beamline | beamline]] dedicated to [[wikipedia:x-ray|x-ray]] micro/nano-diffraction activities at the [[Wikipedia:Advanced Photon Source | Advanced Photon Source]] (APS).


Beamline 34ID-E uses monochromatic and polychromatic micro-beam diffraction to examine the structure of materials with sub-micron spatial resolution in all three dimensions. Properties that can be measured include local crystallographic orientations, orientation gradients and strains.
The x-ray micro/nano-diffraction facility [[X-ray Focusing at 34ID-E | focuses]] x-ray beam to smaller than 0.5&mu;m &times; 0.5&mu;m for use in diffraction techniques using Kirkpatrick-Baez (K-B) mirrors. A specially designed micro-monochromator allows the selection of either polychromatic or monochromatic conditions with a fixed focal spot on the sample.  


The science area brings together a very large and scientifically diverse community with interests in materials deformation processes, recrystallization, electromigration, solid-solution precipitation, high pressure environments, and condensed matter physics
Polychromatic x-ray microscopy utilizes Laue diffraction method to characterize crystalline structure in materials. By scanning a [[differential aperture]], spatially resolved microdiffraction measurements can be made in all three dimensions with sub-&mu;m resolution. Properties that can be measured include the local crystalline phase, local texture (orientation), and the local strains.


== History ==
34ID-E is part of Sector 34ID. After a canting upgrade in 2011, 34ID now has two independently-operated undulators placed in tandem along the ring. X-rays generated by them are horizontally separated. 34ID-E takes the inboard beam, while the outboard beam goes to 34ID-C for [[wikipedia:coherent diffraction imaging|coherent diffraction imaging]] experiments.

Overview

34ID-E is an undulator beamline dedicated to x-ray micro/nano-diffraction activities at the Advanced Photon Source (APS).

The x-ray micro/nano-diffraction facility focuses x-ray beam to smaller than 0.5μm × 0.5μm for use in diffraction techniques using Kirkpatrick-Baez (K-B) mirrors. A specially designed micro-monochromator allows the selection of either polychromatic or monochromatic conditions with a fixed focal spot on the sample.

Polychromatic x-ray microscopy utilizes Laue diffraction method to characterize crystalline structure in materials. By scanning a differential aperture, spatially resolved microdiffraction measurements can be made in all three dimensions with sub-μm resolution. Properties that can be measured include the local crystalline phase, local texture (orientation), and the local strains.

34ID-E is part of Sector 34ID. After a canting upgrade in 2011, 34ID now has two independently-operated undulators placed in tandem along the ring. X-rays generated by them are horizontally separated. 34ID-E takes the inboard beam, while the outboard beam goes to 34ID-C for coherent diffraction imaging experiments.

The development of the microbeam experimental capabilities were sponsored by the DOE Office of Science.
