  1. 698. Status of the SuperCDMS and European Cryogenic Dark Matter experiments
    Dr Gilles Gerbier (Queens University)
    16/06/2015, 15:45
    Particle Physics / Physique des particules (PPD)
    Invited Speaker / Conférencier invité
    The SuperCDMS collaboration operates cryogenic germanium detectors to search for particle dark matter (WIMPs), so far at Soudan Underground Laboratory in Minnesota, US. The EURECA collaboration gathers EDELWEISS, a European collaboration also operating cryogenic germanium detectors, at the Laboratoire Souterrain de Modane, and CRESST who operate cryogenic scintillating detectors (CaWO4) at the...

  2. 789. New Pulse Processing Algorithm for SuperCDMS
    Mr Ryan Underwood (Queens University)

    Particle Physics / Physique des particules (PPD)
    Oral (Student, In Competition) / Orale (Étudiant(e), inscrit à la compétition)
    SuperCDMS searches for dark matter in the form of Weakly Interacting Massive Particles (WIMPs) with cryogenic germanium detectors. WIMPs interacting with atomic nuclei deposit energy in form of lattice vibrations (phonons) which propagate through the cylindrical Ge single crystal (75 mm diameter, 25 mm high) until they are absorbed by the phonon sensors covering part of the flat surfaces of...

  3. 821. Alpha particle backgrounds from the neck of the DEAP-3600 dark matter detector
    Dr James Bueno (University of Alberta)
    16/06/2015, 16:30
    Particle Physics / Physique des particules (PPD)
    Oral (Non-Student) / orale (non-étudiant)
    The DEAP-3600 dark matter detector at SNOLAB will search for scattering of weakly interacting massive particles from a 3600 kg liquid argon target. The liquid argon is held in a spherical vessel made from acrylic, with the highest standards of purity for both bulk acrylic and removal of surface activities. At the top of the vessel there is a neck opening to the cooling system, and alpha...

  4. 727. Optimizing the wavelength-shifter thickness for alpha suppression in the DEAP-3600 detector
    Derek Cranshaw (Queen's University)

    Particle Physics / Physique des particules (PPD)
    Oral (Student, In Competition) / Orale (Étudiant(e), inscrit à la compétition)
    The DEAP-3600 experiment is a spherical dark matter detector searching for WIMPs by detecting scintillation light in a 3600 kg mass of liquid argon. Before the ultraviolet scintillation light passes through the optically clear acrylic vessel and light guides to the surrounding photomultiplier tubes, it must pass through a wavelength-shifting layer of tetraphenyl butadiene (TPB). Trace amounts...
