The Pacific Ocean Neutrino Experiment (P-ONE) is a multi-cubic kilometre neutrino observatory in development off of British Columbia’s west coast, 2600 metres below sea level. P-ONE detects Cherenkov radiation from secondary particles of neutrino interactions in ocean water to ultimately study astrophysical neutrinos. The observatory is comprised of spherical modules with outward-facing PMTs...

The Scintillating Bubble Chamber experiment (SBC) at Queen’s requires a balance between extremes of temperature and pressure, and sensitive detection equipment that needs to be protected from damage as well as background signals throughout the operation of the experiment. The active volume of SBC is cooled by a cryocooler to 90K (-180°C) within synthetic quartz jars that are sensitive to...

Lecture demonstrations are an essential part of physics education, allowing students to foster a more intuitive and meaningful grasp of key scientific concepts. As particle detectors, cloud chambers have the unique property of allowing for real-time, naked-eye visualization of ionizing radiation through the production of a condensate trail in a super-saturated alcohol atmosphere. For this...

May Wittenberg (DEAP-3600)15/08/2022, 12:26Physics Analysis
DEAP-3600 is a large liquid argon detector located 2 km underneath Earth's surface at SNOLAB. DEAP-3600 searches for evidence of dark matter in the form of weakly interacting massive particles (WIMPs), via direct detection. The detector is a spherical acrylic vessel containing 3.3 tonnes of liquid argon. A typical event in DEAP-3600 begins with a nuclear recoil or electronic recoil: this...

Some beyond-standard-model theories, such as the Axi-Higgs model (Leo WH Fung, 2021), suggest the existence of exotic light scalar fields that couple to matter. During high-energy astrophysical events such as binary neutron star (BNS) mergers, these scalar fields may be emitted as radiation. Our project proposes a novel method to detect such radiations, namely, using the Global Positioning...

The Schrodinger Equation (SE) is not just for quantum mechanics; it can describe galactic Dark Matter (DM) too. Fuzzy Dark Matter (FDM) is such a hypothetical model. It comes in the form of a particle so light that its de Broglie wavelength is light years long. The distribution of FDM thus behaves like a density wave, following the SE on the galactic and cosmological scales. Recent simulations...

Victoria Howard (SNO+)15/08/2022, 13:02Physics Analysis
SNO+ is a liquid organic scintillator detector aiming to study neutrinos, which is now completely full of scintillator with the addition of wavelength shifter having been completed.
Within SNO+, there are particles that get tagged as muons by two main criteria. They have large nHit values (the number of hit PMTs per event) and a high number of OWL (OutWard Looking PMT) hits. When a muon is...
