Applications for Beam Time: Advanced Photon Source


Friday, July 10, 2015

The Advanced Photon Source is a synchrotron light source that produces high-energy, high-brilliance x-ray beams. The source is optimized to put large quantities of high-energy photons into a very small area in a very short time.

The x-ray beam is customized at each beamline to meet particular needs. With more than 40 beamlines already operational, and more under development, the APS offers an exceptionally broad range of experimental conditions at a single facility. It is also conveniently located at Argonne National Laboratory, 30 miles southwest of Chicago, Illinois, with two nearby airports offering many travel options.

Scientists from around the world come to the APS to conduct forefront basic and applied research in the fields of materials science; biological science; physics; chemistry; environmental, geophysical, and planetary science; and innovative x-ray instrumentation. To get an idea of the range of work currently being done at the APS, please see the Science section.

All beam time at the APS must be requested each cycle through the web-based Beam Time Access System. Five types of requests are possible: General User, Partner User, Collaborative Access Team (CAT) member, CAT staff, and APS staff. Each beam time request (BTR) must be associated with a proposal, but the requirements for each proposal type differ.
