Coherent X-Ray Diffraction

X-ray diffraction is a technique for studying the characteristics of matter such as macromolecules, crystals, powders, polymers, and fibers.

When x-rays pass through matter, they interact with the electrons in the atoms and become scattered. If the atoms are organized in planes (i.e., the matter is crystalline) and the distances between the atoms are of the same magnitude as the wavelength of the x-rays, then constructive and destructive interference occur and a diffraction pattern forms. Depending on the variety of matter being studied, monochromatic x-rays, pink beam (narrow band) x-rays, or white beam (wide band) x-rays can be used.

PI’s Picks:

PI suggests utilizing one of these exceptional cameras for x-ray diffraction studies:

The Princeton Instruments Quad-RO provides a compact detector design with an IEEE-1394a data interface, electronically balanced quadrants that yield an extremely uniform raw image, dual readout speeds, four-port / single-port readout options, and on-board memory to guarantee loss-free images.

Our compact PIXIS-XF, meanwhile, uses proprietary fiberoptic coupling to preserve the highest spatial resolution, provides high sensitivity for very faint diffracting samples, has a flexible design that allows phosphor removal for system optimization, and features a USB 2.0 data interface. Both models are supported under LINUX.
