Experiments currently searching for dark matter, studying properties of neutrinos require very low levels of radioactive backgrounds both in their own construction materials and in the surrounding environment. These low background levels are required so that the current and next generation experiments can achieve the required sensitivities for their searches. SNOLAB has several facilities...
Many particle and rare-event search detectors use liquid scintillators as the active detector material. Candidate scintillating fluids include liquid noble elements such as Liquid Argon (LAr) and Liquid Xenon (LXe). Detectors that make use of scintillators hold the fluid inside an acrylic vessel, which can be coated with various films. One common coating is 1,1,4,-tetraphenyl-1,3-butadiene...
nEXO is a next-generation neutrinoless double-beta decay experiment that is searching for this decay in 5-tonnes of liquid xenon (LXe) enriched in the isotope 136Xe. Silicon-photomultipliers have been selected to measure the vacuum ultraviolet (VUV) scintillation light from interactions within the LXe. Although candidate SiPMs from Hamamatsu (HPK) and FBK have been characterised within the...
Liquid xenon (LXe) is frequently employed to build detectors for rare event searches due to many of its advantageous properties including high stopping power, high ionization and scintillation yields, and relatively high cryogenic operating temperature. Time projection chambers (TPC) with LXe allow for 3D event reconstruction and identification which is important for reducing backgrounds. Due...
Ionization chambers are widely used for detecting radiation emitted as a result of nuclear decay, and offer potential for high-resolution energy measurement, particle track reconstruction, and for long-lived isotope lifetime measurements. Presently, they are commonly used for measuring the energy of alpha particles emitted during radioactive decay processes and are also used for fission...
