The LUX-ZEPLIN (LZ) experiment is a next-generation search for Weakly Interacting Massive Particles, scaling the very successful double-phase xenon technology to multi-tonne target mass. LZ will be deployed at the 4850-ft level of the Sanford Underground Research Facility (South Dakota, USA) after completion of LUX, which is presently operating there. At its core, LZ will feature a 7-tonne...

The XENON1T detector, currently under construction at the Gran Sasso Underground Laboratory (LNGS) in Italy, is a dual-phase (liquid-gas) xenon time-projection chamber (TPC) for particle detection. It is the successor of XENON100, which reached its sensitivity goal with the last limits on spin-independent WIMP-nucleus interaction (2e-45 cm^2 at 55GeV/c^2), the world-leading result at the time...

Liquid xenon is used in many fields as detector medium. Dark Matter experiments based on liquid xenon have set the most stringent limits in the past decade and are still leading the field. Also in other areas of particle physics xenon is used as detector medium, for example in the search for neutrinoless double beta decay (EXO), in the search for lepton flavor violation (MEG) or in envisioned...

SiGHT stays for Silicon Geiger Hybrid Tube for light detection. Our goal is to construct a modern, high performance, low radioactivity photo detector working at liquid argon and xenon temperature. The idea is to replace the classical dynodic chain of a PMT with a SiPM acting as an electron multiplying detector embedded in a low-radioactive fused silica envelope. This invention would represent...

We present results from measurements to detect proportional scintillation light near thin wires in liquid xenon (LXe). А LXe time projection chamber (TPC) has superior features for the direct detection of Weakly Interacting Massive Particles (WIMPs) as demonstrated by the Xenon10 and Xenon100 experiments and more recently also by LUX.
Future upgrades of these experiments with a TPC...

The next generation of Dark Matter detectors based on dual-phase (liquid/gas) Xenon Time Projection Chambers (TPCs) will require an active volume of liquid with a mass on the tonne-scale in order to reach the desired sensitivity to WIMP-nucleon interactions. One natural and effective way to increase the target mass is to build a TPC with larger cross-sectional area and longer drift distance. ...

The first phase of the Super Cryogenic Dark Matter Search (SuperCDMS) SNOLAB experiment shall consist of a 110 kg array of germanium and silicon athermal phonon detectors. It is expected to reach an order of magnitude better sensitivity than has been achieved so far by the best experiments in the field. The technical challenges of commissioning a payload of this size have led to the...

DAMIC is a novel dark matter search experiment that has a unique sensitivity to hypothetic dark matter particles with masses below 10 GeV. Due to the CCD's low electronic readout noise (R.M.S. ~ 3 electrons), this instrument is able to reach a detection threshold of 60 eV, suitable for the search in the low mass range. The excellent energy response and high spatial resolution of a CCD image...

The Spherical Proportional Counter is a novel type of radiation detector, with a low energy threshold (typically below 100 eV) and good energy resolution. This detector is being developed by the network NEWs, which includes several applications. We can name between many others Dark Matter searches, low level radon and neutron counting or low energy neutrino detection from supernovas or nuclear...

The dual light-emitting crystals can reflect the different ranges of nuclear recoils and electron recoils by the ratio of the two different scintillation components. CsI(Na) crystals at temperatures of ~-100 ℃ have the best performance in several candidate crystals. An experiment called CINDMS is proposed for WIMPs direct searches based on the CsI(Na) crystals detector by IHEP. The 1T-scale...

In modern astroparticle physics, noble gases are often chosen as detector material for a wide range of different experiments. Noble gases can provide a very long electron drift distance which is required for large-scale low-background experiments such as the search for dark matter or for the neutrinoless double beta decay.
Due to the higher density, xenon is often used in the liquid instead...

The solid (crystallin) phase of xenon possesses many of the same advantages of liquid xenon as a particle detector material including good transparency, self-shielding, low intrinsic background, and high scintillation light yield. Many of the properties of solid xenon have been measured previously employing small volumes and thin films. Two major R\&D issues must be addressed to make a solid...
