The collective response of charged particles to intense fields is intrinsic to plasma accelerators and radiation sources, relativistic optics and many astrophysical phenomena. Here we show that a ...

Distinguished for his pioneering studies in X-ray diffraction physics, especially for his development of the technique of X-ray topography, Andrew Lang will be greatly missed by many researchers for ...

This page contains hints, solutions, and advanced challenges for our diffraction grating challenge. If you would like a grating (or a set for your class if you are a teacher), please contact us at ...

A new X-ray diffraction technique that works on single organic molecules has been demonstrated by an international team of researchers. The team hopes that, with further development, the method could ...

In 1967 the Russian physicist Victor Veselago predicted the existence of a material with a negative index of refraction, which he termed “left-handed.” He concluded that in the presence of such a ...

Although electron backscatter diffraction (EBSD) was first discovered by Kikuchi in 1928, its potential for microstructural characterization became fully realized only after the technique was ...

Andrew Lang, Emeritus Professor of Physics at the University of Bristol, died in June. He joined the University in 1960 and was promoted to Professor of Physics in 1979. Andrew Lang, Emeritus ...
