The Super Cryogenic Dark Matter Search (SuperCDMS) experiment uses cryogenic semiconductor detectors to search for Weakly Interacting Massive dark matter Particles (WIMPs). After more than a decade of operations of CDMS and SuperCDMS and a sequence of world leading results, the experimental setup in the Soudan underground laboratory in Minnesota is being decommissioned and SuperCDMS will move...

The GIOVE (Germanium Inner-Outer Veto) detector is a highly sensitive germanium spectrometer used to screen materials for trace amounts of radioactivity. Material screening is an important aspect of the construction rare-event experiments such as GERDA and XENON, which require extremely low background levels. GIOVE is located at the Max Planck Institute for Nuclear and Particle Physics in...

1256. The NEWS-SNO project

Particle Physics / Physique des particules (PPD)

Oral (Non-Student) / orale (non-étudiant)

The existence of Dark Matter in our Universe is nowadays well established, however, its exact nature still remains unknown. The goal of the NEWS-SNO (New Experiments with Spheres in SNOLAB) project is to search for particle candidates in mass regions not yet accessible by existing experiments. The planned NEWS-SNO detector consists of a spherical TPC (time-projection-chamber) out of ultrapure...

1213. Spectroscopic and time-resolved measurements of the fluorescence of pyrene at low temperatures for noble liquid particle detectors

Pyrene is an interesting material because of its wavelength shifting properties. When irradiated with ultraviolet light, pyrene will emit light in the visible wavelengths. This property could be useful for experiments looking to observe scintillation light from noble gases such as argon and neon, which are popular target materials for dark matter direct detection experiments. Noble gases...

Enigmatic dark matter is responsible for 26% of the total mass-energy in the known universe. Since 1997, the DAMA/LIBRA experiment has claimed to have the first direct evidence for the observation of dark matter. One major source of background for this experiment is the 40K isotope. The chemical similarity between potassium and sodium is why trace amounts can be found in the NaI...
