DOI: 10.3791/54660-v
What you'll learn
  • Set up and optimize single crystal X-ray diffraction in a diamond anvil cell
  • Collect high-pressure diffraction data using synchrotron radiation
  • Process and analyze diffraction data using ATREX and RSV software
Protocol

In this report, we describe detailed procedures for carrying out single crystal X-ray diffraction experiments with a diamond anvil cell at the GSECARS 13-BM-C beamline at the Advanced Photon Source. ATREX and RSV programs are used to analyze the data.

Difficulty
advanced
Total time
~4–6 hours per sample (including setup, data collection, and preliminary analysis)

Steps

1
Collect single crystal diffraction data at beamline

Position the diamond anvil cell and sample at the GSECARS 13-BM-C beamline, align optics, and acquire X-ray diffraction images under controlled pressure conditions.
