12. Predicting Oxygen Sensor Failures at SNOLAB using Data Analysis and Machine Learning

Katherine Latosinsky

18/08/2023, 11:00

In the Cube Hall at SNOLAB there are ten zirconium oxide-based sensors that monitor for oxygen deficiency hazards in case of an inert gas leak from the NEWS-G or DEAP-3600 experiments. While important for safety, these sensors occasionally fail, which can disrupt research by triggering a false alarm and evacuation of the Cube Hall. In this presentation I detail my analysis of historic oxygen...

14. Cleaning Data with the Neck Cut in SNO+

SNO+ is a liquid organic scintillator detector aiming to study neutrinos. It is now completely full of scintillator with the addition of wavelength shifter having been completed. Within SNO+, there are events that have been dubbed “neck events”. These events have been named as such because they occur around the neck of the detector and have a characteristic appearance. The neck and bottom...

7. Detecting Radon with a Spherical Proportional Counter

In highly sensitive experiments searching for dark matter, monitoring and reducing background radiation levels is essential. Radon (Rn) is a radioactive noble gas, which can diffuse into experiments, leaving its daughters inside the detector to decay. From the U chain, 222Rn has a half-life of 3.8 days. Some long-lived daughters, like 210Pb will pollute detectors for long periods of time. Most...

25. Scavenger Assay Development

This is a new assay technique that is being developed and characterized for future use on scintillator within the SNO+ experiment.

19. Monte Carlo Simulations of Dark Matter Detectors for SuperCDMS

Sam Paudel (University of Toronto)

18/08/2023, 12:00

The SuperCDMS experiment is a direct detection dark matter (DM) experiment currently located at the SNOLAB underground facility in Sudbury, Ontario. Employing cryogenically cooled silicon and germanium crystals held just above absolute zero, the experiment detects DM particles via nuclear and electron recoils. The High Voltage (HV) detectors boast a low energy threshold granting high...

9. Simulating Magnetic Fields in a Magnetically Shielded Room for a Neutron Electric Dipole Moment Experiment

Thomas Hepworth (The University of Winnipeg)

18/08/2023, 12:15

The discovery of a non-zero permanent neutron electric dipole moment (nEDM) could be direct evidence of new physics beyond the Standard Model, due to its CP violating nature. To measure the nEDM, stable magnetic fields are required. The TRIUMF Ultra Cold Advanced Neutron (TUCAN) collaboration is using a 5-layer Magnetically Shielded Room (MSR) to achieve the required level of magnetic field...
