X-Ray Diffraction

X-ray diffraction (XRD) has a wide variety of applications including phase characterization, crystalline fraction, residual stress, and texture measurements for bulk and powder crystalline materials.

XRD can be performed in reflection transmission geometries.

All XRD machines in the School of Materials Engineering are 'cabinet' analytical X-ray systems that fully shield all high energy radiation from escaping the enclosure and will automatically power off if shielding doors are opened. Radiological and Environmental Management (REM) requires all users to take the online X-Rays (Analytical) online training and submit the results to "MSE-lab-admin@ecn.purdue.edu" prior to training on the XRD equipment.

All new XRD users must first qualify on the D-8 Focus prior to using the more advanced XRD systems.

Training Requirements

  • Valid iLab account
  • Users must be trained on the basic XRD (D-8 Focus) prior to advanced training on either the GADDS or Rotating Anode system including:
    • Complete the Initial Online Training for X-ray Diffraction and Crystallography, take the quiz at the end of the presentation, and email the test results to "MSE-lab-admin@ecn.purdue.edu" (this option is provided on the second page of the online quiz)
  • Subscription to the relevant equipment listserv (individual links provided in the instrument pages) is required before access will be granted. Note: you will receive a confirmation email that you must read and reply to in order to complete registration
  • Training by department lab staff/superuser (request from iLab)
  • ALL of these requirements must be met before Coral permission to an instrument will be granted
  • NOTE: the A-4 form is no longer required by REM for XRD training
