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

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 (, 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
