Cadmium zinc telluride CZT based gamma-ray detector

(Image from Kromek) Introduction Cadmium zinc telluride CZT is a room temperature semiconductor that directly converts x-ray or gamma photons into electrons and holes. It is a unique semiconductor compared with silicon and germanium detectors, in that cadmium zinc telluride CZT operates at room temperature and can process >100 million photons …

X-Ray Fiber Diffraction

Introduction (From Wikipedia) Fiber diffraction is a subarea of scattering, an area in which molecular structure is determined from scattering data (usually of X-rays, electrons or neutrons). In fiber diffraction the scattering pattern does not change, as the sample is rotated about a unique axis (the fiber axis). Such uniaxial symmetry is …

XRD on Powders

Introduction In x-ray diffraction work we normally distinguish between single crystal and polycrystalline or powder applications. The single crystal sample is a perfect (all unit cells aligned in a perfect extended pattern) crystal with a cross section of about 0.3 mm. The single crystal diffractometer and associated computer package is …

Alpha Spectroscopy with Thin Film Adsorption Technicque

Preparation of samples for alpha spectroscopy has always been a critical part of the analysis process. The problem rises from the fact that the interaction of the alpha particles with the massive parts of the sample under analysis reduces the energy with which the particles escape from the sample and …
