The DarkSide-50 is the dual phase Liquid Argon Time Projection Chamber (LAr TPC) based experiment, builded for the direct dark matter search which currently is taking data in the underground facility at Laboratori Nazionali del Gran Sasso (LNGS).
The detector was assembled, tested and filled first with atmospheric Argon (in 2013) and took a successful two years run accumulating the exposure...

The DarkSide Collaboration has started consideration of DarkSide-20k, a direct WIMP search with a Liquid Argon Time Projection Chamber (LAr-TPC) with an active (fiducial) mass of 23 (20) tonnes. The DarkSide-20k LAr-TPC will be deployed in the shield/veto facility already built in support of the DarkSide-50 experiment in the Gran Sasso underground laboratory (LNGS). DarkSide-20k will be a...

DarkSide 20k is a dark matter search experiment whose active target is argon in a double phase TPC. The residual internal background consists in the 39Ar isotope inside the target. The collaboration developed a strategy consisting in the extraction of Argon from underground CO2 wells, than distilled in a very tall cryogenic distillation column. DarkSide 50 already demonstrated the depletion in...

Pyroelectric crystals, such as LiNbO3 or LiTaO3 being under influence of temperature gradient produce electric field up to 106 kV/cm. It was experimentally confirmed that the crystal installed in the chamber with residual gas pressure about 1 mTorr could be used for generation of X-Ray radiation [1,2] with energy up to about 100 keV, as well as electrons [3] and neutrons with energy 2.45 MeV...

We discuss the possibility to produce a modulated monochromatic neutrino beam. Monochromatic neutrinos can be obtained in electron capture by nuclei of atoms or ions. Hydrogen-like ions are of particular interest. It is shown that monochromatic neutrino beam from such hydrogen-like ions with nuclei of non-zero spin can be modulated because of different probabilities of electron capture from...
