The LUX-ZEPLIN (LZ) experiment is a next generation dark matter search designed to achieve unprecedented sensitivity to a wide range of dark matter candidates. At the core of the LZ detector is a dual-phase xenon time projection chamber (TPC) with a 7 ton active mass. LZ will begin taking data in 2020 and achieve a sensitivity of about $1.4\times10^{-48} cm^2$ at $40~GeV/c^2$ WIMP mass after...
In 2018 the XENON1T experiment set the most stringent constraints on the interaction cross-section between nucleons and Weakly Interacting Massive Particles. A crucial role for the inference of such results is played by the accurate modelling of the detector response.
We report about a new calibration test with a $^{37}$Ar source diluted into the liquid xenon, performed in the XENON1T...
The DARWIN observatory will be the ultimate xenon-based detector for WIMP dark matter complemented by a rich science program of other rare event searches. It will operate 40t of natural liquid xenon in a time projection chamber, combining light- and charge-signal measurements for background reduction and an optimal energy resolution. We aim at reducing all background sources for the WIMP...
The liquid argon (LAr) detector technology has strong potential to push the sensitivity for WIMP detection several orders of magnitude beyond current levels. The Global Argon Dark Matter Collaboration includes scientists from all the major groups currently working with this technology with the goal to build a sequence of future detectors that maximally exploit the advantages of LAr as a...
DEAP-3600 is a tonne-scale, liquid argon (LAr) experiment searching for Weakly Interacting Massive Particles (WIMPs), which are a leading candidate for dark matter. The detector is located at SNOLAB in Sudbury, Ontario, and comprises 3279 kg of LAr as a scintillator, viewed by 255 photomultiplier tubes (PMTs). While DEAP is optimized for detecting WIMPs at recoil energies on the order of 10...
The Scintillating Bubble Chamber (SBC) experiment is a new low-background technique aimed at detecting low-mass (0.7-7 GeV/c$^{2}$) WIMP interactions and reactor CEvNS. The detector consists of a quartz-jar filled with liquid Argon (LAr), spiked with 100 ppm of liquid Xenon (LXe) acting as a wavelength-shifter, and instrumented with Cameras, Silicon-Photo-Multipliers and Piezo-acoustic...
NEWS-G (New Experiments With Spheres-Gas) is an experiment searching for dark matter using the Spherical Proportional Counter (SPC) technique. Such detectors can operate kg scale targets in meter sized spheres, while keeping single ionization electron detection sensitivity. They can be filled with low mass gases such as hydrogen, helium, and neon. NEWS-G aspires to extend the sensitivity of...
The Cryogenic Underground Test (CUTE) facility, installed at SNOLAB, is designed for testing and characterization of cryogenic detectors in a low-background and low-vibration environment. The cryostat that provides the low operating temperatures of ~15 mK is surrounded by a layered shielding of water and low-activity lead leading to an estimated background of order of a few events/(keV.kg.d)...
SABRE is a particle dark matter experiment whose aim is to conclusively test the claim of dark matter detection by the DAMA collaboration, who have measured an anomalous annual modulation in their NaI:Tl detector for many years. To this end, SABRE has developed NaI:Tl crystals of unsurpassed purity, which will serve as a low-background target and operate submerged within a large liquid...
Ongoing experiments are searching for dark matter or coherent neutrino scattering signals via the identification of nuclear recoils using germanium and silicon as detector materials. At the sub-keV recoil energy scales being probed by the latest generation of such experiments, the ionization yield of nuclear recoils in germanium and silicon is an important, but poorly characterized, material...
