1. Quality assurance plan for the TeA plant

The SNO+ detector is located 2km underground in Sudbury, Ontario. The primary purpose of the experiment is to study extremely rare neutrinoless double beta decay using Te-130 as the double beta decay isotope. Te-130 was chosen due to it’s high natural abundance and high energy double beta decay end point. The detector will be initially loaded with 0.5% Tellurium which corresponds to 4 tons of...

2. Sample Analysis Methodology for Telluric Purification

The SNO+ detector is a multi-tonne liquid scintillator neutrino detector located 2000 m underground near Sudbury, Ontario. In order to search for the proposed neutrinoless double beta decay (0νββ), the SNO+ scintillator cocktail will be loaded with tellurium-130. The 130Te will come from telluric acid, which is synthesized with butanediol before being added to the scintillator. The detector is...

21. Finding Primordial Black Holes via their Photon Rings

The Event Horizon Telescope image of the photon ring around M87*, a black hole, captivated the world, and this achievement was named Breakthrough of the Year by Science Magazine in 2019. How could we use these photon rings to detect primordial black holes? Since light can orbit around a black hole, instead of looking for black holes through gravitational lensing events, in which we can only...

11. Deeply Learning the Position Reconstruction of Antihydrogen Annihilations in ALPHA-g

Ashley Ferreira (TRIUMF (CA))

The ALPHA-g experiment at CERN aims to perform the first-ever direct measurement of the effect of gravity on antimatter, determining its weight to within 1% precision. At TRIUMF, we are working on a new deep learning method based on the PointNet architecture to predict the height at which the antihydrogen atoms annihilate in the detector. This approach aims to improve upon the accuracy,...

5. Radon-222 Gas Assays of the SNO+ Detector

The SNO+ detector is located at SNOLAB 2km underground in Sudbury, Ontario. SNO+ is a large multipurpose detector looking for an extremely rare and proposed neutrino-less double beta decay, if observed will determine the Majorana nature of neutrinos. Therefore, backgrounds that may obscure the data are consistently monitored. Being underground prevents backgrounds from the cosmic flux,...
