Undergrad High Resolution X-Ray Diffraction: Explained

Click For Summary
High resolution X-ray diffraction (HRXRD) refers to a technique that offers greater angular resolution compared to standard X-ray diffraction, allowing for more precise measurement of crystal spacing. The term "regular" X-ray diffraction may not be commonly used, as HRXRD is simply a more refined version of the technique. HRXRD is particularly useful for studying deviations in crystal structures, analyzing individual diffraction peaks, and examining defects in materials. It is often employed in the characterization of thin layers with potentially distorted structures. The enhanced resolution is achieved through the use of advanced components like monochromators and mirrors, while the fundamental principles of X-ray diffraction remain consistent.

Hello
What does it mean when people say high resolution xray diffraction? What is the difference between regular Xray diffraction and high resolution X-ray diffraction?

Thank you

Is there a such thing as "regular" X-ray diffraction?

It's possible that the hi-rez is simply describing that X-ray diffraction is higher-rez than other forms of diffraction (say, visible light). This because X-rays are higher frequency.
 
The resolution in this case refers to the angular resolution of the system, which in turn translates into how precise the crystal spacing can be measured. The HRXRD is usually used to study deviations from the ideal crystal structure, the structure of individual diffraction peaks, defects and probably other things. It is used in characterization of thin layers, which may have distorted structure. As I understand, it is just a matter of more sophisticated components (monochromators, windows, mirrors, mechanics) but the principle is the same as for any XRD.

Thread 'Time rondeau crystals, experimental observations'

A relative asked me about the following article: Experimental observation of a time rondeau crystal https://www.nature.com/articles/s41567-025-03028-y I pointed my relative to following article: Scientists Discovered a Time Crystal That Reveals a New Way to Order Time https://www.yahoo.com/news/articles/scientists-discovered-time-crystal-reveals-180055389.html This area is outside of my regular experience. I'm interested in radiation effects in polycrystalline material, i.e., grain...
