Our facility is located in room A353 Weeks Hall. Campus researchers trained in the use of the instrument are encouraged to make full use of the analytical capabilities and expertise offered by this laboratory at a modest cost. We offer training in basic theory and technique. Download a copy of our User's Manual (pdf).

Sign up for time on the calender. Check out the scheduling rules. Latest information about the status of the instrument is posted on the calender, at the very top of the page. Always check out that message. Our laboratory features a Scintag PADV X-ray Diffractometer. Review its analytical capabilities. To learn more about XRD, visit links at the Univ. of New Mexico XRD lab's page. There are also class notes from the course that Jim Connelly teaches there. Excellent!

Professor Huifang Xu (email) is in charge of the XRD lab and is assisted by Dr. Hiromi Konishi (email), phone (608) 262-0915 (lab); (608) 262-9784 (office).

XRD Costs

• Hourly charge for machine is $15/hour.
• Hourly charge for training is $40/hour for labor. The training cost can be split by having several (maximum 3) students being trained at the same time.
• Previously prepared samples may be run by Hiromi or Huifang for individuals upon prior consultation.

Training

New Users: All new users MUST undergo training in order to use this machine. While previous XRD experience on similar machines will facilitate your learning experience, training (1-2 hours) on the Scintag hardware and software is MANDATORY. Violators of this rule are responsible for all repair costs and will be denied further access to this facility.

Scheduling Rules

General use hours are Mon noon-5, and Tues-Fri 8-5, advanced users may use the XRD after hours. No one may use the XRD overnight (10 pm -6 am) without permission from Hiromi or Huifang. No one may use the XRD on the weekend (10 pm Friday night-6 am Monday morning) without permission from Hiromi or Huifang.

Please be on time for your session! We have many users competing for time and the schedule fills up quickly. If no one is using the instrument 20 minutes after a scheduled session, that time is then freely available. Therefore, if you if you are more than twenty minutes late for your session, you may lose your time. Caveat emptor.

Capabilities of Scintag PAD V

On May 28, we installed a new Cu Ka X-ray tube, rated at 2000 Watts. We intend to operate it at 45 kV and 40 mA (exceptions: previous users who wish to continue to run their samples at 40 kV and 35 mA will be permitted).

Analytical capabilities:

Powder Diffraction: Particle sizing, Strain analysis, Phase identification, Structure refinement, Quantitative phase composition, Lattice parameter determination, Characterization of amorphous components, Pole Figures Texture (preferred orientation), Single crystal orientation determination, Bicrystal orientation determination.
