Coherent X-Ray Diffraction

Coherent X-Ray Diffraction

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.

X-ray diffraction studies the characteristics of matter such as macromolecules, crystals, powders, polymers, and fibers. 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.

Cameras for Coherent X-Ray Diffraction

PIXIS XF photo


For detection of indirect x-rays in the <3 keV to >20 keV energy range, the PIXIS XF provides the highest sensitivity and spatial resolution through fiberoptic coupling, essential for x-ray diffraction. This allows for detection of even very faint diffracting samples.

The unique mechanical design allows for outstanding flexibility. Specialized, removable phosphor screens allow for optimization of the system, with the PIXIS XF coming with a choice of front- or back-illuminated CCDs for different experimental design.

With excellent >95% QE over the energy range 5 eV – 30 keV, and large sensor formats, the SOPHIA-XO is optimal for direct x-ray diffraction detection within this range.

X-ray diffraction is sample dependent, so requires flexibility within experimental set-up between samples. The SOPHIA-XO has the ability to reach high frame rates with multiple port readouts, ideal for frequent experimental changes.

The SOPHIA-XO offers low read noise for high resolution x-ray diffraction studies, separating the diffraction pattern produced.

Some x-ray diffraction patterns are faint and require direct detection. The PIXIS-XB is the ideal camera for low-flux applications, with sensitivity over the energy range 3-20 keV.

Deep, thermoelectric cooling, created using a thin beryllium window to vacuum-seal the unit, protects the CCD and reduces background interference.
