The APS is a open user facility that makes beam time available to the international scientific community through a peer-reviewed proposal process.
Two access modes are available: General Users and Partner Users. General Users are those who require less than 10% of the beam time on a beamline in a given cycle. Partner Users are those whose work involves a greater scope and greater commitment by both the user and the APS. Specific requirements govern both modes of access.
