The goal of the NEWS-G (New Experiments with Spheres filled with Gas) project is to search for galactic Dark Matter particles in the GeV mass region. Used detectors are constituted of spherical metallic vessels equipped with small ball sensors set at high voltage at center of sphere, filled with noble gas mixtures (Ar, Ne, He, H), operated in proportional mode.

One of the most pressing question in modern physics arises from the growing evidence that dark matter constitutes the vast majority of the universe's content. The PICO collaboration searches for dark matter particles using superheated fluid detectors, or bubble chambers. These detector can be made inherently insensitive to gamma and beta radiation, while the additional background suppression...
Hypothetical dark-matter particles could make up the bulk of the matter in the universe. Spherical gaseous detectors, like the one being planned by the NEWS-G experiment at SNOLAB, could investigate the existence of low-mass dark-matter particles. An important property to characterize is the quenching factor of such detectors, ie the ratio of signal created by the nuclear recoils expected to...
The IceCube Neutrino Observatory, completed in 2010, is the world's largest neutrino detector, using a cubic kilometer of Antarctic ice as a Cherenkov medium. With the inclusion of the DeepCore low energy extension, the observatory is able to analyze neutrinos down to 6 GeV in energy, enabling a wide variety of particle physics research in addition to the high energy astrophysics for which it...
