The DARWIN design study aims to use liquid argon and liquid xenon targets to look for nuclear recoils due to Weakly Interacting Massive Particles. To measure the recoil energy in dual-phase noble gas time projection chambers the combination of scintillation and ionisation detection is used to discriminate nuclear from electron recoils. Current experiments use an array of photomultiplier tubes...

The XENON experimental program is aimed at the detection of Dark Matter in the form of Weakly Interacting Massive Particles (WIMPs), using liquid xenon as target and the 'double phase' technique to discriminate nuclear recoils (the signature of WIMPs) from the ordinary radioactive background. The XENON colaboration has already deployed two successful detectors at the Gran Sasso Laboratory. I...

For future neutrino oscillation experiments new large mass scale detectors are needed. One possible type of such detectors could be a liquid Argon Time Projection Chamber (LArTPC). Some technical challenges need to be addressed, like the purity of the LAr, the high voltage supply and calibration. To face these challenges, an R\&D program named Argontube is in progress at the LHEP of Albert...

Results are presented from a small-scale experiment to investigate the use of room temperature organic liquid scintillators as the active medium for a time projection chamber (TPC).
The optical properties of liquid scintillators have long been known, but their ability to transport charge has remained, until now, largely untested. The idea of using room temperature liquids as an active...

The Enriched Xenon Observatory (EXO) experimental program is searching for the neutrino-less double beta decay of xenon-136. A first stage experiment called EXO-200 is running at the WIPP salt mine in New Mexico, and has made the first measurement of the standard electroweak 2-neutrino double beta decay of Xe-136. EXO-200 uses 200 kg of xenon enriched to 80% in the 136 isotope, a large...

In this work we report on a new development of Silicon Drift Detectors (SDDs) for gamma-ray spectroscopy for astronomy applications, an activity supported by ESA. The SDDs are designed as monolithic arrays of 3x3 units, each one of an active area of 64mm$^2$ (total array area of 5.76cm$^2$). These arrays will be assembled on a common substrate to be used as photodetector to read out large...

The Large Underground Xenon (LUX) is a dark matter direct detection experiment being deployed at the Homestake Mine in South Dakota, USA.
The LUX detector is a dual-phase Xe TPC, with a total liquid Xe mass of 350 kg. It measures both scintillation and ionization produced by radiation interacting in the liquid Xe to differentiate between the nuclear recoils expected from WIMPs and
the...

Recently, the upgrade of the Virgo gravitational wave detector was kicked off with the installation of the new seismic attenuation system for the external injection bench. In the next two years the sensitivity of Virgo will be improved by an order of magnitude and it is believed that with its improved capability, Advanced Virgo will herald the era of gravitational wave astronomy.
The...

The Alpha Magnetic Spectrometer (AMS-02) is a high-energy physics experiment designed to operate in space on board the International Space Station (ISS), where it has been installed on May 16th 2011. Thanks to the very large acceptance ($\sim$0.5 m$^2$ sr) and an exposure time of several years, matching the ISS lifetime, AMS-02 will measure a wealth of data to study with unprecedented accuracy...

The Pierre Auger Observatory explores the potential of radio detection techniques to measure extensive air showers (EAS) induced by ultra-high energy cosmic rays. To study in detail the mechanisms responsible for radio emission in the MHz range, the Auger Engineering Radio Array has been installed at the Observatory. Presently consisting of 24 radio-detection stations, this number will grow to...
