Research Collaborations

X-ray Absorption Fine Structure Spectroscopy Studies,


The research in this group involves the use of x-rays and electrons for probing the structure of solids, liquids, surfaces, and interfaces. Specifically, we use x-ray absorption spectroscopy, x-ray scattering and x-ray reflectometry to study the structure of materials and nanoscience for energy-related research, and is involved in collaborations on a variety of environmental and biological problems, such as biomineralization and the structure of biofilms. In addition to x-ray experiments, we use transmission electron microscopy and diffraction, optical measurements, and a number of other materials characterization tools.

The x-ray research largely requires the use of very intense x-rays available only at national synchrotron-radiation sources. To that end, the group is part of the Materials Research Collaborative Access Team (MRCAT) a multiple-institution consortium that constructed and now operates two x-ray beamlines at the Advanced Photon Source located at Argonne National Laboratory. Experimental instrumentation includes microfocussing optics, an 8-circle goniometer, 2D CCD detector, and multielement x-ray fluorescence detectors for time- and spatially-resolved x-ray scattering, reflectivity, and XAFS to study a variety of materials, environmental, and biological problems.



The Joint Institute for Nuclear Astrophysics - Center for the Evolution of Elements (JINA-CEE)

Jina Cee

The Joint Institute for Nuclear Astrophysics - Center for the Evolution of the Elements (JINA-CEE) is the successor institution of JINA. JINA-CEE research addresses fundamental questions about the evolution and properties of matter in the cosmos, and the origin of the chemical elements that makeup our world, as Carl Sagan aptly summarized: "we are made of star stuff". Understanding the origin and evolution of matter requires to study detailed features of atomic nuclei and connect them with observations of stars and stellar explosions. 

JINA-CEE brings together nuclear experimentalists, nuclear theorists, astronomers, theoretical astrophysicists, and computational physicists in a unique cross-disciplinary research network that enables rapid communication and coordination across field boundaries and connects research at new accelerator facilities, observatories, and model codes in new ways. 

JINA fosters interdisciplinary collaborations, workshops, research programs, and educational initiatives at its participating institutions as well as within the field of nuclear astrophysics at large. We invite the scientific community - astrophysicists and nuclear physicists - theorists and experimentalists - in the US and world wide to actively participate in this endeavor to advance science and make this project a useful resource for the field of nuclear astrophysics. 

The Large Binocular Telescope (LBT)


The Large Binocular Telescope Observatory (LBTO) is located in southeastern Arizona near Safford in the Pinaleno Mountains on Emerald Peak at an altitude of 3200m. This area is part of the Coronado National Forest. LBTO is headquartered on the Tucson campus of the University of Arizona. 

The binocular design of the Large Binocular Telescope (LBT) has two identical 8.4 m telescopes mounted side-by-side on a common altitude-azimuth mounting for a combined collecting area of a single 11.8 m telescope. The entire telescope and enclosure are very compact by virtue of the fast focal ratio (F/1.14) of the primary mirrors. 

The two primary mirrors are separated by 14.4 m center-to-center and provide an interferometric baseline of 22.8 m edge-to-edge. The binocular design, combined with integrated adaptive optics utilizing adaptive Gregorian secondary mirrors to compensate for atmospheric phase errors, provides a large effective aperture, high angular resolution, low thermal background, and exceptional sensitivity for the detection of faint objects. 

The LBT is an international collaboration of the University of Arizona, Italy (INAF: Istituto Nazionale di Astrofisica), Germany (LBTB: LBT Beteiligungsgesellschaft), The Ohio State University, and the Tucson–based Research Corporation representing the University of Minnesota, the University of Virginia, and the University of Notre Dame.

Vatican Advanced Technology Telescope (VATT)


The Vatican Observatory Research Group (VORG) operates the 1.8m Alice P. Lennon Telescope with its Thomas J. Bannan Astrophysics Facility, known together as the Vatican Advanced Technology Telescope (VATT), at the Mount Graham International Observatory (MGIO) in southeastern Arizona where sky conditions are among the best in the world and certainly the Continental United States.

Fermilab DØ Experiment:
1.8 TeV Proton Antiproton Collisions


The DØ Experiment consists of a worldwide collaboration of scientists conducting research on the fundamental nature of matter. The experiment is located at the world's premier high-energy physics laboratory the Fermi National Accelerator Laboratory (Fermilab) in Batavia, Illinois, USA. The research is focused on precise studies of interactions of protons and antiprotons at the highest available energies provided by the Tevatron collider. It involves an intense search for subatomic clues that reveal the character of the building blocks of the universe. The DØ experiment finished data collection in 2011 when the Tevatron collider run ended and now is analyzing the collected data set..

CERN Compact Muon Solenoid, CMS


The CMS Collaboration brings together members of the particle physics community from across the globe in a quest to advance humanity’s knowledge of the very basic laws of our Universe. CMS has over 4000 particle physicists, engineers, computer scientists, technicians and students from around 200 institutes and universities from more than 40 countries.

The collaboration operates and collects data from the Compact Muon Solenoid, one of the general-purpose particle detectors at CERN’s Large Hadron Collider. Collaborators from all over the world helped design and fabricate components of the detector, which were brought to CERN for final assembly. Data collected by CMS are shared with several computing centres via the Worldwide LHC Computing Grid. From there, they are distributed to CMS institutions in over forty countries for physics analysis.

In keeping with CERN’s commitment to open access for high-energy physics, the scientific results from CMS are shared openly with the world.


The BaBar Collaboration


Building on the original 2200-meter PEP storage ring and in cooperation with LBNL and LLNL, SLAC is constructing an extensive upgrade called the B Factory which will produce millions of B mesons. This upgrade includes modifications to the PEP storage ring and a new type of detector, called BaBar. The BaBar detector consists of a silicon vertex detector, a drift chamber, a particle identification system, a CsI electromagnetic calorimeter, and a magnet with an instrumented flux return. The B Factory will include a second ring of magnets and other devices to increase the particle collision rate 50 times more than the original facility. This high collision rate is necessary for the study of the matter-antimatter asymmetry. The BaBar collaboration consists of around 600 physicists and engineers from 72 institutions in 9 countries.
