Silicon Photomultipliers (SiPMs) are compact arrays of single-photon avalanche diodes (SPADs). The Vacuum Emission Reflection Absorption (VERA) apparatus is a custom setup developed at TRIUMF, used to measure photon detection efficiency and reflectivity of SiPMs in a vacuum chamber at cryogenic temperatures. Photon detection efficiency is one of the most critical parameters of any single...
The Single Photon Air Analyzer project (SPAA) aims to develop proof-of-concept for a new optical particulate matter detector. This detector is novel in that it uses the scattering angle of photons to determine the size of particulate matter in air. An array of silicon photomultipliers (SiPMs), solid-state sensors capable of single-photon resolution, will count small numbers of photons...
The study of new BiPo214 nhit cuts for 1.1 g/L and 2.2g/L. Previously, the SNO+ project was using the nhit cuts from 0.5g/L, we are going to evaluate how the nhit cuts changes and how that affects the tagging efficiency. After looking at how the different nhit cuts affect the tagging efficiency we also have to consider the accidental rate.
CUTE is a test facility currently testing high voltage detectors for SuperCDMS in hopes that they will one day detect dark matter. These detectors need to be calibrated to get an understanding of the response we get during a run. CUTE currently has a system installed that is used for gamma calibration. This talk will outline the progress made during the winter and spring term for the...
Devices that can produce images of gamma ray sources in the energy range from 100 keV to several MeV have applications in astronomy as well as safety and security. The technology of choice in this energy range relies on the phenomenom of Compton scattering. A gamma ray scatters in the front layer of the detector, giving up some of its energy. The scattered, lower-energy photon is then...
There are several candidates in the broad search for dark matter. Prevalent among them is an ultralight particle interacting via some scalar field, which would induce an isotropic strain on all condensed bodies. Our dark matter detector (HELIOS) aims to measure this effect in the 2 kHz frequency range, and thus requires strong vibration isolation in that range. We have created a new kind of...
