Liquid scintillators are a commonly used detection medium for particle and rare-event search detectors. The vessels containing the liquid scintillator are often made of transparent acrylic. In the case of a UV-emitting scintillator, to make the scintillation light observable, the acrylic can be coated with a wavelength shifter like 1,1,4,4-tetraphenyl-1,3-butadiene (TPB). Another coating of...
Radon is one of the most troublesome backgrounds in dark matter and neutrino detectors. Nitrogen is commonly used in cover gas systems at SNOLAB, such as in the SNO+ detector. To determine the concentration of radon in them, a method of extraction and counting has been developed with the help of radon traps at cryogenic temperatures. I present our methodology and the progress made on...
High-purity germanium detectors are used in the search for rare events such as neutrinoless double-beta decay, dark matter and other beyond Standard Model physics. Due to the infrequent occurrence of signal events, extraordinary measures are taken to reduce background interactions and extract the most information from data. An efficient signal denoising algorithm can improve measurements of...
Aerogel threshold Cherenkov counters are developed to identify pions and muons in the range of 240-980MeV/c for the T9 beam test facility at CERN PS East Hall. These counters are part of the Water Cherenkov Test experiment (WCTE) particle identification system. The WCTE is a test-beam
experiment to test the design and capabilities of the photosensor system under development for the...
The High Energy Light Isotope eXperiment (HELIX), a multistage balloon-borne detector, aims to measure the composition of light cosmic-ray isotopes up to 10 GeV/n. One of the primary scientific objectives of HELIX is to study the propagation of cosmic rays in our galaxy by measuring the ratio of Be_10 and Be_9 fluxes. The detector's first stage, which will measure cosmic rays with energies up...
The TRIUMF Ultracold Advanced Neutron (TUCAN) collaboration is building a surface coating facility at the University of Winnipeg. The primary purpose of this facility is to prepare ultracold-neutron (UCN) guides to transport UCNs from the TUCAN source to the TUCAN Electric Dipole Moment (EDM) experiment. UCN losses during the transport can be minimized by the application of special coatings....
