Crystallography (IMAGE)
Caption
Principle of crystallography: The electron beam (blue) passes through a magnetic slalom course, called an undulator, where the electrons send out X-ray light that adds up to short laser-like pulses. The X-rays produce a characteristic diffraction pattern when they hit a crystal of the sample. The pattern is recorded by a detector and analyzed with computers to reveal the spatial structure of the crystal's building blocks, which are the biomolecules under investigation.
