Acquisition software, an upgrade of which we completed in 2001, provided the ability to perform step scans (for high precision), transmission pole figures and azimuth scans (both for preferred orientation analysis). Scans were highly customizable, either coupled or with independent control of each individual axis (3 circles). Up to 16 individual zones can be programmed in a single acquisition.
The available data-processing software included routines to find and fit peaks, remove background, determine integrated peak areas, display and compare spectra graphically, and search the PDF database for matching patterns.
NOTE for New Users: The Radiation Safety Section of OEHS requires that all new XRD users read a manual section on XRD-safety procedures and, along with their advisor, sign a statement indicating they have read and understood the material. Ideally this should precede the start of XRD training. The manual section is available on the OEHS website. The required forms are available in the lab. The training process we employ is rather direct, comprised initially of proceeding through all steps while you observe, then in the next subsequent session you proceeding through all steps while we observe that you are observing all the relevant procedures and protocols.
