In rare event searches, minimizing backgrounds is essential to obtaining high sensitivity. Many Weakly Interacting Massive Particle (WIMP) detectors employ powerful tools such as pulse shape discrimination to differeniate between electronic recoils and nuclear recoils; since WIMPs are expected to produce nuclear recoils, the total background rate can be drastically reduced. Liquid argon-based...
The SNOLAB facility is located within an active mine, and as such the experiments housed there are subject to daily seismic activity, both planned and unplanned. For this reason, A hydrophone has been installed within the water shielding tank of DEAP-3600, an ultra-low background dark matter experiment, to act as a seismograph and to identify and timestamp seismic activity. This presentation...
For many years now, terahertz imaging has been applied to many fields. In this work, we experimentally demonstrate THz Fourier imaging. We use a lens to generate the Fourier transform of a transmission object. Then, we measure the Fourier plane using a THz detector mounted on a 3D stage. First, we demonstrate that using the conventional inverse Fourier transform the image can be reconstructed...
Weak-value amplification (WVA) is a technique that has been used in a variety of experimental settings to permit the precise measurement of small parameters. WVA is a special instance of a more general measurement strategy that involves sorting data into separate subsets based on the outcome of a second ``partitioning'' measurement. Whether or not WVA has an actual advantage in terms of the...
Medical imaging such as positron emission tomography (PET) and high energy physics experiments such as time imaging calorimetry are among examples that would benefit from better timing resolution and use time-of-flight (ToF) measurements to improve image contrast or mitigate pileup. The single photon timing resolution (SPTR) is the timing resolution of the photodetector and readout electronics...
Gamma-ray spectroscopy is a powerful tool used in a variety of fields including nuclear and analytical chemistry, environmental science, and health risk management. At Simon Fraser University Nuclear Science Laboratory (SFU NSL), the Germanium detector for Elemental Analysis and Radiation Studies (GEARS), a low-background shielded high-purity germanium gamma-ray detector, has been used...
