Rare event detection with Liquid Argon

Dark matter has never been physically measured although it represents the majority of all matter in the Universe. Neutrinos are the most numerous particles in the Universe, but their masses and the way they obtain it, are still unknown

DarkSide-50 Dark Matter Search

is searching for dark matter particles via their collisions with argon nuclei. We rely on rejecting any other particle interactions in deep underground laboratories. The "undeground" argon, has much lower intrinsic radioactivity with respect to "atmospheric" argon. We contributed to detector commissioning and are heaving involved in data analysis. We are also working on the development of detectors components for the future DarkSide-20k detector. LAr technology has unique background rejection capabilities to reach sensitivities up to and beyond so called ”neutrino floor”, where neutrino-induced coherent scattering on nuclei starts contributing to the background.

Precision neutrino physics

Precision measurements of specific neutron spallation cross section in LAr within local R&D project (BACon), and of neutron spallation backgrounds and neutrino interaction strengths in LAr detectors within Mini-CAPTAIN experiment.
DUNE large-scale international LAr experiment will investigate the pattern of neutrino mass and mixing, and the role they play in astrophysics and cosmology.
We collaborate with local Prof.Svoboda's group on all precision neutrino physics projects. We contributed to the development and operation of BACoN, photon-detection system in mini-CAPTAIN experiment and development of realistic MC generator (MARLEY). We are presenty involved in HV Dune/ProtoDune group. See more @


SiGHT photosensor R&D

Development of novel hybrid photosensor SiGHT with a less challenging design, enhanced performance and radiopurity to further advance dark matter searches. We collaborate with UCLA group on this exciting project. See more @

ARIS project

Argon Recoil Ionization and Scintillation (ARIS) experiment will make precision measurements of low energy argon nuclei recoils induced by monoenergetic directional neutrons in a 3D position sensitive argon detector and investigate if detector response depends on the argon recoil direction with respect to the applied electric field. These measurements will provide several important scientific inputs for current and future LAr based experiments designed for direct detection of dark matter particles. We collaborate with several reasarch groups on this international project. See more @
