The XRD measurements performed in transmission mode (X-ray beam penetrates through the sample, detector is placed behind of it) with polychromatic X-ray beam of 160 kVp. Anisotropic scattering patterns indicate presence of texture in the sample structure. Color coding in these images shows powder signal in red, reflections from larger crystals in green and mean energy in blue. An AdvaPIX camera was used to create this image.

X-RAY DIFFRACTION AND CRYSTALLOGRAPHY

Applications: Material Analysis

X-ray diffraction is an analytical method based on the inspection of the crystalline structure of samples. Applications can be found in metallurgy, mineralogy powders, pigments, polymers surface layers, or strain mapping. Our spectral imaging detector is the key to the next level of material analysis.

The traditional XRD uses monochromatic X-rays, which make the apparatus large and slow. ADVACAM’s spectral camera, based on a Timepix3 chip with high resolution, makes it fast and compact. Instead of taking a single diffraction image accumulating all X-ray energies (wavelengths) as performed in the traditional XRD apparatus, we record about 150 images at once. One picture for each energy channel. Due to this enhancement, the system operates at a speed two orders of magnitude faster than conventional XRD systems.

The high-resolution detector can be placed close to the sample covering a large solid angle, leading to fast data accumulation. Moreover, our cameras can handle a broad energy range (3 – 150 keV). Therefore, even heavy samples such as stainless steel, heavy metals, and minerals, can be transmitted.

ADVACAM Material Analysis: X-RAY DIFFRACTION AND CRYSTALLOGRAPHY: The basic principle of the "Energy Dispersive X-ray Diffraction" (EDXRD) in transmission geometry: The spectral sensitivity of our detectors enables us to record dozen of images during a single measurement. Each image corresponds to a single wavelength. This way all primary energies contribute to the final XRD image instead of being lost in the monochromator. The measurement is, therefore, significantly faster (Circa 100x).
