Laue Camera
Our group has access to a real-time Laue camera system, using a Cu radiation x-ray source. We use this for the characterization and alignment of crystals grown in our lab.

X-ray Scattering
X-ray scattering is one of the main techniques that our group uses to investigate new materials. Our group operates a rotating anode x-ray source at the NHMFL which is equipped with an image plate Guinier camera and low temperature stage. This enables us to conduct high-resolution scattering experiments down to at least 8 K. With our current set-up, powder patterns take less than 5 minutes to obtain a reasonable dataset from 0 degrees to 90 degrees in two theta.

The combination of the rotating anode plus the Guinier camera will enable us to study a wide variety of problems, such as:
- Lattice distortions which relieve frustration in transition metal oxides
- The existence of exotic order parameters in heavy fermion systems
- Spin-Peierls transitions in transition metal oxides
- Charge ordering in spinels and other materials
- Charge inhomogeneity in high-Tc cuprates and other highly correlated electron systems
The long-term goals of our group consist of:
- Expanding our measurements down to a temperature scale of 1 K or less.
- Building a proto-type magnet to conduct high resolution diffraction in magnetic fields of up to 6 T.
- Combining these efforts to have the capability to conduct low-T, high magnetic field diffraction experiments on single crystals and powders.
