LAUE: Laue Back-Reflection of X-Rays

X-rays scattering is one of the most powerful methods used worldwide to understand the structure of materials, from high temperature superconductors to proteins and other macromolecules. This experiment primarily looks at crystal planes in single crystals using a technique involving constructive interference of X-rays.

Max von Laue won the Nobel Prize in Physics in 1914 "for his discovery of the diffraction of X-rays by crystals". Other Nobel Prizes involving crystallography include Lawrence Bragg and William Bragg (Physics 1915), Peter Debye (Chemistry 1936), Watson, Crick, and Wilkins (Medicine 1962), Dorothy Hodgkin (Chemistry 1964), Bertram Brockhouse and Clifford Shull (Physics 1994), Ramakrishnan, Steitz, and Yonath (Chemistry 2009), Dan Shechtman (Chemistry 2011), and many more
