Diffraction Facility

About Us

Housed in the Joint Institute for Advanced Materials (JIAM) at The University of Tennessee, Knoxville, we are the JIAM Diffraction Facility.  Individuals from academia, national labs, and industry utilize the facility to perform a wide range of experiments.  Basic usage revolves around the identification and quantification of phases, crystallinity, lattice parameters, crystallite size, and microstrain.  More advanced uses include high-temperature in-situ experiments, investigating preferred orientation with pole figures, determining residual stresses, and studying thin films with X-ray reflectivity, among others.  If you would like more information or have any questions, you can explore this site and/or email Michael Koehler (lab manager).


For X-ray diffraction, we have an Empyrean and X’Pert3 MRD systems from Malvern Panalytical. The Empyrean has both copper and cobalt tubes, and the MRD has only copper. For X-ray fluorescence, we have an Epsilon 1 EDXRF system from Malvern Panalytical. More information can be found here.


Our users include individuals from academia, national labs, and industry. Individuals from UTK can use account numbers for payment.  All others can be direct billed or establish a Facilities Membership with the Center for Materials Processing to gain access to an account number for an easy payment option.  Contact Michael Koehler (lab manager) at Michael Koehler for more information.


We offer training on our instruments and analytical software for individuals who want to perform their own experiments.  If you would rather have us perform the measurements and/or analyze the data for you, that option is also available. Information regarding our rates can be found here.
