  1. 20. Improving Gravity Spy's Classification Accuracy of Real Gravitational Wave Events and Excess Noise Artifacts
    Seraphim HSIEH JAROV (University of British Columbia)

    Physics Analysis

    A key issue in the search for Gravitational Waves (GWs) by the Advanced Laser Interferometer Gravitational Wave Observatory (LIGO) and Advanced Virgo detectors surrounds the presence of excess noise transients (glitches) that pollute the detector data. These glitches come from a range of sources and can often mimic the form of real astrophysical events. To distinguish between real events and...

    Engineering

    SNO+ designed an Umbilical Retrieval Mechanism (URM) to deploy radioactive sources for the calibration of the detector. The sealed URM must maintain a near zero differential pressure between itself and the air pressure in the underground laboratory thus requiring a Pressure Equalizing System.

    The Pressure Equalizing System consists of a Cover Gas Bag designed to adjust its volume to...

  3. 22. Finding Functional Approximations of the Absolute Counting Efficiencies for radon 222 and radon 220 for ESC’s under certain Pressures and High Voltages
    Drake Wickman (nEXO)

    Instrumentation/Hardware

    Construction materials for equipment used in experiments contain natural radioactivity. High energy photons and beta rays towards the end of the uranium and thorium chains can act as a source of background for experiments like the original SNO experiment. To mitigate this, construction materials are required to be ultra low radioactivity materials. This requires methods to measure the...

  4. 25. Particle Discrimination Using Machine Learning Techniques
    Megan McArthur (SNOLAB)
    23/08/2021, 16:30
    Physics Analysis

    The PICO experiment utilizes a bubble chamber to search for weakly interacting massive particles (WIMPs). Events in the detector generate acoustic signals due to bubble creation caused by energetic incident particles, e.g., alpha particles, neutrons, gammas, or WIMPs. A use of these acoustic signals is to distinguish among the different events triggered by different types of incident...

  5. 12. Alpha and Beta Discrimination in SNO+ in Partial Fill and Scintillator Full Phase
    Caroline Deluce (SNOLAB)
    Physics Analysis

    SNO+ is one of SNOLAB’s neutrino focused detectors, and is located 2km underground at Vale’s Creighton Mine, in Sudbury, ON. The detector itself is composed of a spherical acrylic vessel (AV) that has a radius of 6m, which is currently in a period of holding liquid scintillator - linear alkylbenzene (LAB) and PPO (wavelength shifter), before it is loaded with Tellurium-130. The AV is centered...
