Sector/Beamline Locations & Phone Numbers

Building numbers are for sections (pentagons) of the Lab Office Modules (LOMs) located around the ring. The Beamlines page provides a map.

Phone numbers are for the work areas on the Experiment Hall floor. From on site, dial 2, then the four-digit number listed for the beamline. From off site, dial 630-252-xxxx (the four-digit number listed).

APS beamlines are managed and operated either by a group in the X-ray Science Division (XSD) or by a Collaborative Access Team (CAT) or Collaborative Development Team (CDT). For contact information for a particular beamline scientist or for details about the beamline, consult the link on beamline number in the Beamline Directory.
