X-Ray Facility

A broad range of x-ray diffraction capabilities are available within the School of Materials Engineering.

Armstrong Hall of Engineering XRD Facility

This is the School of Materials Engineering's main facility which is located in ARMS 2093.  The diffractometers are available to Purdue University students, faculty and researchers who have received the necessary safety and practical training.  Undergraduate students gain experience on these instruments in MSE 335 and MSE 367.  Many undergraduate students then go on to use these instruments for their Senior Design (MSE 430 and 440) and independent research projects (MSE 499s).   

Instruments

Bruker D8 Focus X-Ray Diffractometer:

This instrument is equipped with a Cu Kα source, a rotating stage, and a high speed 1D Lynxeye detector.  It is configured in vertical theta/2theta Bragg-Bretano geometry.  There is an ICDD PDF2 database for indexing patterns.

Measurement Capabilities are:

  • Qualititative phase analysis
  • Quantitative phase analysis
  • Structure solution and refinement
  • Crystallite size determination

Bruker D8 Focus X-Ray Diffractometer:

Bruker D8 Discover X-Ray Diffractometer with GADDS (General Area Detector Diffraction System):

This instrument uses a High Star 2D detector to collect large amounts of data simultaneously. This allows for very fast phase identification, as well as the ability to quickly identify preferred orientation and collect pole figures to quantify the orientation distribution. It is equipped with Cu Kα or Cr Kα sources and a choice of incident-beam collimators to probe specific areas of a sample (microdiffraction). It is configured with an Open Eularian Cradle for tilt (ψ) and rotation (φ) of sample and a motorized xyz stage for positioning of sample.

Measurement Capabilities are:

  • Rapid powder characterization
  • Texture analysis
  • Small Angle X-Ray Scattering
  • Residual Stress analysis
  • Single Crystal Diffraction

 Access

To gain access to the Materials Engineering's Armstrong Hall of Engineering XRD Facility, individuals must complete the following steps.

  1. Complete REM X-Ray Safety Training: Analytical & Diagnostic.
    • Go to: www.purdue.edu/rem/rs/rstrain.htm#XT .  Select the Analytical & Diagnostic training module, read the information, complete and submit the exam.
    • Print out your completion email to confirm that you passed the online exam.
    • Fill out your Form A-4, but do not send it to REM.  It must be signed by the MSE Project Director  Jameson Root ARMS 2309  and he will forward it to REM.
  2. Become a registered user of the Materials Engineering’s XRD Faculties.
    • You must have an ECN login and Coral Account prior to scheduling training.  If you are outside of the College of Engineering, contact ECN to obtain an account at engineering.purdue.edu/ECN/Support/Accounts/Request/.
    • Prior to being trained, your advisor needs to set up a Coral account for you at engineering.purdue.edu/CORAL/.  Contact coral@ecn.purdue.edu if you have problems setting up the account.
    • To schedule Instrument Training, send a message to mse-xrd-admin@ecn.purdue.edu.  (You can not be trained on the GADDS until you have been trained on the D8 Focus.  You should contact the GADDS mail list and request training from one of the superusers.  It will take a  number of sessions to complete GADDS training and become an independent user.)
    • Bring proof of REM training and a blank copy of Form A-4: http://www.purdue.edu/rem/home/forms/A-4.docx to the training.
    • Also bring a sample to be examined to the training session.
  3. When the training is complete, join the Mail List for the instrument or instruments of interest.  engineering.purdue.edu/ECN/mailman/listinfo
  4. Reservations are made using Coral.
    • Users who have completed the above steps will be granted access to the Materials Engineering: XRD Facility and be able to reserve time on the instruments that they have been trained to use. 
  5. To request card swipe access:  /MSE/Research/Facilities/CardSwipeAccess XRD/index_html
