 Condensed Matter & Materials
Inelastic X-ray & Nuclear Resonant Scattering (IXN)

Primary Contact: Thomas Gog
Research Disciplines: Condensed Matter Physics, Geophysics, Materials Science

The IXN Group uses the brilliance and unique timing structure of the APS to study the dynamical properties of matter. For inelastic x-ray scattering, the APS provides the energy resolution and access to large volumes of reciprocal space for probing the lattice and electron dynamics of novel materials, while for nuclear resonant scattering, it provides timing patterns that allow access to a wide range of Mössbauer isotopes.

Magnetic Materials (MM)

Primary Contact: Daniel Haskel
Research Disciplines: Physics, Materials Science

The MM group operates 5 beamlines (4-ID, 6-ID, 29-ID) that focus on the study of magnetic, electronic, and structural properties of condensed matter systems using x-ray scattering and spectroscopy techniques.

Materials Physics and Engineering (MPE)

Primary Contact: Jonathan Almer
Research Disciplines: Materials Science and Engineering, Condensed-Matter Physics

The MPE group exploits the unique properties of high-energy x-rays for in situ studies of materials under a range of temperatures, pressures, and electro-chemical conditions. A large fraction of these studies cannot be done at any other facility in the United States. The high penetration of these x-rays enables a range of sample environments to be utilized and bulk studies to be performed on realistically-sized samples. 

Surface Scattering and Microdiffraction (SSM)

Primary Contact: Jon Tischler
Research Disciplines: Materials Science, Physics, Chemistry

The SSM group develops and applies x-ray capabilities for determining the structure of surfaces, interfaces, and thin films. Research in the group focuses on characterization of epitaxial films including during growth in a molecular beam epitaxy (MBE) chamber and using a unique white beam µ-Laue setup to determine the polycrystalline configuration of surfaces and films in functional materials.

Time-Resolved Research (TRR)

Primary Contact: Alec Sandy
Research Disciplines: Materials Science, Condensed Matter Physics, Atomic and Molecular Physics

The TRR group operates a set of beamlines (7-BM, 7-ID, 8-ID) that apply x-ray techniques (XPCS, GSAXS, pump-probe) to measure the dynamic behavior of a variety of systems on times scales from ns to seconds.

 Chemistry and Imaging
Chemical and Materials Science (CMS)

Primary Contact: Randy Winans
Research Disciplines: Chemistry, Materials Science

The CMS operates 3 beamlines for small-angle and wide-angle scattering, grazing-incidence scattering, spectroscopy equiped with specialized reaction cells for in situ and operando experiments. The beamlines are used to primarily address problems in energy storage  and catalysis.

GMCA Structural Biology Facility (MX)

Primary Contact: Robert Fischetti
Research Disciplines: Biology, Life Sciences

Imaging (IMG)

Primary Contact: Francesco De Carlo
Research Disciplines: Materials Science, Biology, Physics, Life Sciences

The IMG group designs, supports, and operates state-of-the-art x-ray instrumentation and scientific software for 2-D and 3-D full-field imaging.  Development efforts focus on optimizing for speed, sensitivity, and resolution by taking full advantage of the unique properties of the APS source, such as the time structure, the high energy, and the low emittance. This allows for multi-scale imaging of real materials — in real time — and under real conditions

Microscopy (MIC)

Primary Contact: Stefan Vogt
Research Disciplines: Materials Science, Biology, Physics, Life Sciences

The MIC Group carries works on the development and applications of hard x-ray microscopy.  The program uses x-ray optics-based microprobes and nanoprobes to probe real space, reciprocal space, and in particular, elemental content and local chemistry, and coherent diffractive imaging-based approaches to extend achievable spatial resolution in x-ray microscopy beyond limitations set by x-ray optics.  

Spectroscopy (SPC)

Primary Contact: Steve Heald
Research Disciplines: Materials Science, Environmental Science, Chemistry, GeoScience

Structural Science (SRS)

Primary Contact: Pete Chupas
Research Disciplines: Materials Science, GeoScience, Physics, Chemistry, Environmental Science

The scientific programs of the SRS group focus on the study of the structure of materials, both on a short-range scale using PDF methods and x-ray absorption spectroscopy, and also on a longer‑ length scale using high-resolution powder diffraction and single-crystal diffuse scattering. In situ, operando or time-resolved (i.e., pump-probe) studies are major themes of the group. 

Beamline Technologies
Beamline Controls (BC)

Primary Contact: Pete Jemian

The BC group develops software and electronic hardware for synchrotron radiation beamlines that serves the common needs of APS researchers, and implements software for the APS Beamlines.

Beamline Instrumentation (BI)

Primary Contact: Michael Fisher

Beamline Instrumentation group provides engineering support for novel synchrotron radiation equipment.

Detectors (DET)

Primary Contact: Antonino Miceli

The detector group develops new types of detectors for synchrotron radiation research that are not available commercially.  In addition, it manages the detector pool which provides novel detector systems to all APS beamlines.

Primary Contact: Lahsen Assoufid

The Optics group operates and develops instruments to fabricate and characterize x-ray optical elements, such as single crystal monochromators, mirrors, multilayers, and other special substrates.

Scientific Software Engineering and Data Management (SDM)

Primary Contact: Nicholas Schwarz

The Scientific Software Engineering and Data Managment group provides flexible, customer-oriented software services to the accelerator and beamlines in support of world-class photon science at the APS. These services are rendered through the application of our core competencies: embedded software, software engineering, distributed control systems, information systems, high performance computing, and graphical user interfaces.

The Computational X-ray Science group supports activities in XSD through:

  • Development of algorithms and core competencies in computation & theory.
  • Collaboration with XSD scientists and software engineers on scientific data solutions.
  • Coordination with APS, Argonne, and external organizations on present & future XSD computational needs.
