Welcome to the 1-ID beamline at the Advanced Photon Source (APS) located at Argonne National Laboratory (ANL). This beamline is operated by the Materials Physics & Engineering Group (MPE) of the APS X-ray Science Division (XSD).

1-ID provides brilliant, high-energy x-ray beams which combine high penetration power with spatio-temporal resolution.  Approximately 80% of the available 1-ID beamtime is accessible to users through the General User program. 

Techniques available at the two end-stations (1-ID-C and 1-ID-E) are listed below.  These are frequently conducted in-situ, with environments provided by the APS or brought by users.

• High-energy small- and wide-angle x-ray scattering (SAXS/WAXS)
• High-energy diffraction microscopy, in near-field, far-field and very-far-field modes (NF-, FF-, VFF-HEDM)
• High-energy x-ray tomography
• Pair-distribution function (PDF) including resonant PDF.
• Up to 3D imaging through use of diffracted beam apertures

The 1-ID beamline has been operational since the start of the APS in the mid 1990s, and has been used to develop a variety of synchrotron techniques and instrumentation, many of which are now in use at other APS beamlines.  Since ~2010 it has been more dedicated to developing and delivering the high-energy x-ray techniques listed above.
