Dark Matter Search with the PICO-40L Bubble Chamber
… currently operating the PICO-40L experiment at SNOLAB in Sudbury, Ontario, Canada. PICO-40L, the first large-scale implementation of the so-called "right side up" design, has been constructed over the past several years and has recently to gather open data for the characterization of …

Calibration and background data analysis in the scope of the NEWS-G dark matter experiment
… as a preparation for its future operation at SNOLAB starting in 2021. A paper from this data is in the final stages of preparation, and this thesis describes my work related to data analysis. More concretely, this thesis first explores the sphere conditions that affect the electron drift time. …

Light Dark Matter Constraints from a SuperCDMS Cryogenic Silicon Detector with Single-Charge Sensitivity
… The SuperCDMS (Cryogenic Dark Matter Search) SNOLAB experiment is a next-generation direct detection effort using cryogenic germanium and silicon detectors to measure phonon and ionization signals from dark-matter recoils. It aims to improve sensitivity to dark-matter particles with masses …

Analysis of vacuum and argon gas fill data from the MiniCLEAN dark matter experiment
… of ongoing detector assembly 2 km underground at SNOLAB in Ontario, the complete instrumented inner vessel was commissioned by collecting photomultiplier waveform data for periods when the vessel was evacuated and when filled with warm argon gas. Alpha decay events from radon progeny on the …

Calibration of Infrared Photons in Cryogenic Germanium Detectors
… built. The new phase of SuperCDMS experiment at SNOLAB is aiming to be sensitive to the lower WIMP mass scale. Therefore, a lower background and detector threshold energy is a necessity, and the detectors need to be calibrated and tested for the new proposed sensitivity. The tests include high …

The Development of the SNO+ Experiment: Scintillator Timing, Pulse Shape Discrimination, and Sterile Neutrinos
… detector which is under construction in the SNOLAB facility in Sudbury, Ontario. SNO+ will search for neutrinoless double beta decay, and will measure low energy solar neutrinos. This thesis will describe three main development activities for the SNO+ experiment: the measurement of the timing …

Detection of Solar Neutrino Absorption and Study of TPB and Acrylic Fluorescence in DEAP-3600
DEAP-3600 is a liquid argon experiment located at SNOLAB whose principal goal is to observe WIMP dark matter. There are many DEAP-3600 analyses that can use the high livetime of the ultra-low background LAr detector to expand the scientific output of the experiment. With recent hardware upgrades, …

High-energy Neutron Backgrounds for Underground Dark Matter Experiments
… for the dark matter experiment SuperCDMS SNOLAB, an active neutron veto was developed. It is estimated that the current design of the neutron veto with a 40 cm thick layer of boron-doped liquid scintillator can achieve a >90% efficiency for tagging the single-scatter neutrons. In addition, …

The PICO-2L program: Towards Background-Free Dark Matter Direct Detection Using Bubble Chambers
The PICO-2L program commenced in 2013 with the deployment of a 2 litre bubble chamber filled with superheated C3F8 and over the next three years, conducted two separate WIMP-search experiments. The first run was conducted at 4 different energy thresholds ranging from 3.2 keV to 8.1 keV and a total …
