Powder X-Ray Diffraction

Procedures for powder X-ray diffraction samples will be changing, please check back often.

To submit samples for powder X-ray diffraction, complete this form, and bring it and your sample to Dr. Unruh. At present, only simple collection of powder-diffraction data is available without prior discussion of requirements.

User Training

Those wanting to collect their own data must adhere to the following procedure.

  • Complete EHS Radiation Safety Training here.
  • Apply to Dr. Unruh to get added to the radiation sub-license
  • Be trained to the satisfaction of lab personnel in all necessary aspects of instrument use, including: instrument preparation, sample handling and mounting, data collection and processing.
  • Demonstrate the ability to correctly handle the instrument for setup, data collection, processing, and returning the instrument to its ready state.

After this, users will be considered trained and capable of using the Ultima III.

Booking sheets are available for trained users to book time-slots for data collection on the Ultima III. All users must book their time-slots, and fill in instrument logbooks in a timely manner; otherwise they will lose access to the instruments. Trained users wanting non-standard data-collections, or unusual conditions, must first discuss these in advance of their booked session with Dr. Unruh.
