Proton induced x-ray emission pixe
WebbParticle-induced X-ray emission or proton-induced X-ray emission (PIXE) is a technique used in the determining of the elemental make-up of a material or sample. When a material is exposed to an ion beam, atomic interactions occur that give off EM radiation of wavelengths in the x-ray part of the electromagnetic spectrum specific to an element. … WebbAbstract: Proton induced X-ray emission (PIXE) uses proton beam to excite the atoms in the specimen resulting in the emission of the characteristic X-rays of its elemental …

Webbprotons of a few MeV and X-ray detection by a silicon detector yields a powerful multi-elemental analysis method. This is especially true for trace elements, elements occurring in a weight fraction below 100 ppm. This method, generally referred to as PIXE (Particle Induced X-ray Emission) (Joh76a), was further developed by many research workers
