Beamline 2-BM-A,B: Micro tomography Imaging

X-ray Science Division, APS
Physics, Life Sciences, GeoScience, Materials Science


The sector 2 bending magnet beamline is fully dedicated to microtomography with capability to perform large field of view (20x2 mm^2) fast 2D phase contrast imaging for slow dynamic phenomena studies (0.1m/s). The applications of this beamline range from life science [1], geoscience [2, 3], physics [4], material science and engineering [5, 6], and paleontology [7]. The flexibility of switching setups and capabilities of developing on-demand accessory experimental techniques make this beamline versatile in tomography applications.


Supported Techniques

  • Tomography
  • Phase contrast imaging

Beamline Controls and Data Acquisition

The beamline is run using Linux Workstations (RedHat). Tomographic data analysis is performed using TomoPy (http://www.aps.anl.gov/tomopy/), an open source Python toolbox developed by the APS Imaging Group to perform tomographic data processing and image reconstruction tasks. Beamline control is done though VME crates and EPICS.


  • CCD/CMOS detectors
  • Scintillation detectors
  • Energy dispersive solid state detector

Additional Equipment

  • Fast x-ray tomography system
  • Micropositioning system
