Invited Speaker / Conférencier(ère) invité(e)

The SNOLAB laboratory is located deep underground in the Canadian Shield and hosts several science experiments which require extremely low levels of background radiation. The deep underground facilities provide significant rock overburden and thus a reduction in the cosmic ray flux and cosmic ray-spallation induced products, such as neutrons. Nevertheless, even when an experiment is deep...

568. Utilization of Quantum Dots for Radiation Detection Applications

Oral (Non-Student) / Orale (non-étudiant(e))

Quantum dots exhibit size-dependent characteristics because of quantum confinement at the nanoscale. This leads to the possibility of controlling their electronic and optical properties, including the band gap. While these tunable properties of quantum dots have been exploited in photonic applications, their use in radiation detection remains comparatively unexplored. When illuminated by...

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

As modern physics experiments begin to require lower and lower backgrounds to reach their sensitivity goals, be it dark matter searches or experiments seeking to probe the nature of neutrinos, new technology is needed in order to reach these stringent requirements. In the realm of light detection devices, silicon photomultipliers (SiPMs) offer an upper-hand in terms of radiopurity when...

903. The ARGO detector readout and DAQ

Prof. Audrey Corbeil Therrien (Université de Sherbrooke)

Applied Physics and Instrumentation / Physique appliquée et de l'instrumentation (DAPI / DPAI)

Oral (Non-Student) / Orale (non-étudiant(e))

Physicists continue to invest significant effort in the search for dark matter using increasingly large and sensitive detectors. ARGO is a next generation experiment in conceptual development designed to push sensitivity through advanced photodetection and large-scale instrumentation. The detection medium is a ~400-tonne mass of low-background argon inside an acrylic vessel. To capture the...

611. Monte Carlo modeling of pixelated digital SiPMs for the ARGO dark matter experiment

Applied Physics and Instrumentation / Physique appliquée et de l'instrumentation (DAPI / DPAI)

Oral (Non-Student) / Orale (non-étudiant(e))

ARGO is a future dark matter direct-detection experiment based on a liquid argon (LAr) target proposed to be constructed at SNOLAB in the next decade. ARGO will produce leading sensitivity to heavy dark matter searches above 50 GeV/c2. It will also have excellent sensitivity to detect core-collapse supernova neutrinos and produce high-precision measurements of solar neutrinos at and above the...
