Leybold Products Digital Laue Diagrams: Investigating The Lattice Structure of Monocrystals

The X-ray image sensor allows capturing the Laue pattern in one minute (much faster than conventional film) and the digital evaluation eases the determination of the diffraction angles on the computer.

To create Laue diagrams of NaCl and LiF monocrystals, the bremsstrahlung of the X-ray apparatus is used in the experiment P7.1.2.5 as a "white" spectrum of  X-rays. The positions of the "multicolored" diffraction spots on an X-ray image sensor behind the crystal and their intensities can be used to determine the crystal structure and the dimensions of the unit cell through application of the Laue condition.
