AbstraktAbstract
Spectral X-ray imaging is a fast developing field with many possible applications in a variety of fields. CERN (Conseil Europeen pour la Recherche Nucleaire), along with other members for the Medipix3 Collaboration, has developed the Timepix3 chip, which provides hit-by-hit information from X-ray photons interacting with a segmented semiconductor detector. A full radiographic setup comprising a micro-focus X-ray source, sample holder with rotation stage and detector displacement stage is available in the ESE-ME Section. As a first task the setup has to be completed in order to provide the possibility of performing Computer Tomography (CT) scans of small objects. Furthermore, the limits of detection for various concentrations of metallic materials should be studied using the spectroscopic information provided by Timepix3 with the aim of establishing detection limits as a function of spectroscopic fidelity and dose. The experimental work will be accompanied by detailed physics simulations.
