It aims to detect Long-Lived Particles (LLPs), a theoretical particle predicted by Beyond the Standard Model theories that could explain current unsolved physics mysteries. This project focused on the characterization of components that would make up the final detector, such a wavelength shifting optical fibres (WLSFs) and silicone photomultipliers (SiPMs). Studies included measuring the timing resolution of the WLSFs and the temperature dependence of the SiPMs. Such characterization is necessary to ensure the final detector meets theoretical specifications.enphysicsparticle physicsexperimental physicshigh energy physicsPoster
