Welcome to Sector 1 of the Advanced Photon Source (APS) located at Argonne National Laboratory (ANL). The Sector 1 beamlines are part of APS X-ray Operations and Research (XOR) organization and are operated by the X-ray Physics Group, which is part of the APS Experimental Facilities Division (XFD).

Sector 1 consists of the 1-ID and 1-BM beamlines, and 80% of the available beamtime is accessible to outside users through the General User program. The main programs pursued at these two beamlines are described below.

1-ID is dedicated to providing and using high-energy x-ray beams (45-180 keV) for the following activities:

• High-energy x-ray optics development
• High-energy x-ray scattering techniques
  • Pair distribution function measurements
  • Powder diffraction
  • Single grain observations in polycrystals
  • Stress/strain/texture studies
  • Diffuse scattering
  • Small angle scattering
  • Flourescence

1-BM is a multi-purpose beamline delivering x-rays in the 6-24 keV range for the following activities:

• Powder diffraction
• Fuel spray studies
• Reflectivity
• Small angle scattering
