PICO-500 is a WIMP dark matter bubble chamber detector in its early stages of construction underground at SNOLAB. It is the upscaled successor of PICO-40L, which is currently operational with the objective of detecting dark matter or improving the world leading spin-dependent WIMP search limits set by PICO-60 in 2016. PICO-500 will have almost an order of magnitude greater sensitivity with a...
The PICO collaboration searches for dark matter using superheated C3F8 in bubble chamber technology. The results of the operation of the PICO-60 detector at SNOLAB set the most stringent direct-detection constraint to date on the weakly interacting massive particle (WIMP)-proton spin-dependent cross section.
PICO-500 is the next-generation detector produced by PICO with a 250 kg live volume....
The SuperCDMS collaboration uses cryogenic silicon and germanium detectors to directly search for dark matter. Among the full payload of 24 detectors are 12 HV detectors. These utilize a bias voltage across the crystal substrate to amplify the phonon signal created from particle energy depositions. We have operated 4 Ge and 2 Si HV detectors in a deep underground environment for the first time...
SuperCDMS SNOLAB will be a direct detection experiment with world-leading sensitivity to low-mass dark matter (DM) that employs cryogenic silicon and germanium calorimeters. SNOLAB detectors are expected to exhibit a non-linear energy response, necessitating calibration signatures across the entire energy range of interest. A calibration method proposed for silicon-based detectors is to use...
