The university of Qatar positron research group at the moment uses two positron techniques (lifetime and Doppler broadening) to study several types of materials such as; metals, alloys, polymers, semiconductors, etc.

Positrons (antimatter electrons) are very sensitive probes of materials; they seek out defects and yield information via a study of the photons arising from their annihilations with localised electrons. During the last 40 years or so positron physics has become one of the emerging and vastly developing areas of research. The positron technique is a non-destructive tool to test the structure of materials that can be conducted by many of the companies and factories that produce any type of materials. It is particularly sensitive to open spaces of very small sizes that cannot be detected by other methods. There is also a medical application namely, Positron Emission Tomography, (PET) that can be used in scanning the brain and other parts of the body.
