The laboratory is located in Hoffman 305 and operated by Dr. William J. Croft. The powder diffractometer employs a theta-theta goniometer. Its operation is controlled by a MicroVAX 3100 computer and generates complete Intensity vs. Scattering angle scans automatically as a basic function. Installed DMS 2000 software also allows pattern indexing, unit cell determination, precision lattice parameter determination, and Reitveld analysis.

The Berman Laboratory honors the work of Associate Professor Harry Berman, one of the world's foremost mineralogists, who lost his life in an aircraft accident in World War II while working on the quartz oscillator project for the U.S. Government. This laboratory is set up with a variety of x-ray powder cameras, including Gandolfi, Guinier, and a micro camera. Single crystal instruments, Weissenberg, Precession, and Laue cameras, are also available.
