M1-1 Dark Matter Experiments I (PPD) | Expériences sur la matière sombre I (PPD)
- Mark Patrick Hartz (TRIUMF & Kavli IPMU, University of Tokyo)
Astronomical and cosmological observations strongly suggest that most of the matter in our Universe is non-luminous and made of an unknown substance called Dark Matter. But, currently, it remains invisible and undetectable directly on Earth and makes it one of the greatest mysteries in particle physics. Even if its direct detection escapes to the scientific community in our time, dark matter...
Cryogenic detectors offer excellent resolution and sensitivity for low mass dark matter searches but require testing in a well-shielded, low background environment for complete characterization. The Cryogenic Underground TEst (CUTE) facility is located 2 km underground in SNOLAB near Sudbury, ON. CUTE has served as a well-shielded, low background site for the testing, characterization and...
DEAP-3600 is a single-phase dark matter experiment looking at direct detection elastic nuclear scatters of the dark matter candidate, Weakly Interacting Massive Particles (WIMPs), with 3279 kg of liquid argon. The DEAP detector has recorded more than 3 years of physics data, and in addition to the direct search of dark matter, the collaboration is also working to extend the sensitivity of the...
The SuperCDMS collaboration uses cryogenic silicon and germanium detectors to directly search for dark matter. Dark matter particles in the mass range of 1-10 GeV/$c^2$ interacting via nuclear recoils would deposit energies below 1 keV. Such interactions produce both phonons and electron-hole pairs. The number of electron-hole pairs produced per unit energy deposited in an electron recoil,...
The Super Cryogenic Dark Matter Search (SuperCDMS) Collaboration uses cryogenic semiconductor detectors to look for evidence of dark matter interactions with ordinary matter. The current generation is under construction at SNOLAB, and will use two target materials (silicon and germanium) and two detector types (HV and iZIP) to probe low mass dark matter.
For potential future upgrades,...
