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, which has, after a canting upgrade in 2011, 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 into 34ID-C for coherent diffraction imaging experiments.
The development of the microbeam experimental capabilities were sponsored by the DOE Office of Science.

Data Analysis
|
- Analysis and visualization are mostly done with LaueGo, a package developed at 34ID-E based on IGOR Pro, runs on any PC or Mac.
- Data from depth-resolved measurements requires reconstruction, which is carried out by a multi-node Linux cluster at APS.
