Synchrotron-Related Theory
Synchrotron-Related Theory (SRT) provides a link between x-ray experiments and
materials science and theory. Areas of expertise include x-ray spectroscopy, magnetism,
spin transport and strongly-correlated materials. SRT is a joint program supported by Northern
Illinois University and the APS.

Beamline Technical Support
Beamline Technical Support maintains an x-ray detector pool to assist APS users with data collection, and
an equipment pool to provide various experimental hardware for short-term loan.
Primary Contact: Patricia Fernandez, fernandz@aps.anl.gov
Optics Fabrication and Metrology
Optics Fabrication and Metrology (OFM) operates and develops instruments to fabricate
and characterize x-ray optical elements, such as single crystal-monochromators, mirrors, multilayers,
and other special substrates. In addition, OFM works with the APS user community to develop new optics for special beamline applications.
Primary Contact: Albert Macrander, atm@aps.anl.gov
User Administration and Support
User Administration and Support (APS User Office) provides direct and indirect administrative
and support services to APS and CNM users. Direct services include registration, orientation/training/badging,
developing and maintaining user information Web pages, writing and distributing electronic newsletters and other
electronic communications, and administering scientific access systems (General and Partner User programs).
Indirect services include workshop, conference, and meeting support, (especially for the annual Users Meeting,
the quarterly APSUO Steering Committee and Partner Users Council meetings, the annual Scientific Advisory
Committee meeting, and Sector Reviews), as well as outreach activities that promote the availability of beam
time at the APS.
