Liquid Argon (LAr) Time Projection Chambers (TPC) operating in double-phase detect the nuclear recoils (NR) possibly caused by the elastic scattering of dark matter WIMP particles via light signals from both scintillation and ionization processes.
In the scenario of a low-mass WIMP (< 2 GeV/c^{2}), the energy range for the NRs would be below 20 keV, thus making it crucial to characterize the...
The DarkSide-50 (DS-50) experiment uses underground argon (UAr) as a target for the detection of WIMPs, one of the prime candidates for dark matter searches. During the transportation from Colorado (US) to Gran Sasso (Italy) cosmic ray interactions produce $^{37}Ar$ in the UAr. Narrow peaks corresponding to L-shell (0.27 keV) and K-shell (2.82 keV) electron capture are visible in the DS-50...
The TREXDM detector, a low background chamber with microbulk Micromegas readout, was commissioned in the underground laboratory of Canfranc (LSC) in 2018. Since then, data taking campaigns have been carried out with Argon and Neon mixtures, at different pressures from 1 to 4 bar. The two challenges currently faced are the reduction of the background level and the improvement of the energy...
CYGNO, a directional Dark Matter TPC optically readout
We are going to discuss the latest R&D progress concerning the enhancement of the light yield in the CYGNO experiment. CYGNO is a directional detector for low mass (0.5-50 GeV) Dark Matter WIMP searches. The experiment is focused on developing a high-precision and optically readout gaseous Time Projection Chamber and, given its...
The Scintillating Bubble Chamber (SBC) Collaboration is combining the well-established bubble chamber and liquid argon scintillator technologies to build a detector specifically suited to the quasi-background-free measurement of low energy nuclear recoils. This relies on the principle that nuclear recoils induce bubble formation (nucleation) while electron recoils do not, allowing bubble-based...
The recent detection of the coherent elastic neutrino-nucleus scattering (CEνNS) opens the possibility to use neutrinos to explore physics beyond standard model with small size detectors. However, the CEνNS process generates signals at the few keV level, requiring of very sensitive detecting technologies for its detection. The European Spallation Source (ESS) has been identified as an optimal...
The neutrino-nucleus coherent scattering (CEνNS), known as CEνNS, has the highest cross-section among all interaction channels for MeV neutrinos, making it the most promising way of remote monitoring and detection of nuclear reactors. The biggest challenges are lowering the energy threshold to keV and sub-keV and mitigating the cosmogenic background in a sea-level detector. A liquid xenon time...
