Beamline 2-ID-E: Hard X-ray Microprobe Facility

X-ray Science Division, APS
Life Sciences, Environmental Science, Materials Science

Description

The 2-ID-D/E microprobe facility operates three hard x-ray microprobes for x-ray fluorescence mapping, fluorescence spectroscopy, and microdiffraction. Station 2-ID-D houses an x-ray fluorescence and a microdiffraction microprobe that operate independently. Station 2-ID-E houses an x-ray fluorescence microprobe in a side-branch geometry that operates in parallel to either of the 2-ID-D instruments.

Supported Techniques

Microfluorescence (hard x-ray)

Beamline Controls and Data Acquisition

The beamline is run using Sun workstations (UNIX/Solaris) using various EPICS-based applications. A user interface allows simple operation for users with little prior beamline experience. Custom software “MAPS” allows analysis of full fluorescence spectra at each pixel.

Detectors

Silicond Drift Detectors (single element + 4 element), Vortex
Ionization chambers
Configured detector for differential phase contrast

Additional Equipment

Leica DMXRE Epi-fluorescence microscope
