One of its primary goals is to observe and characterize neutrinos coming from a supernova burst in the Milky Way and surrounding galaxies. In the case of a...

We are going to present the CYGNO/INITIUM project for the development of a high precision optical readout gaseous Time Projection Chamber (TPC) for directional Dark Matter search and solar neutrino spectroscopy, to be hosted at Laboratori Nazionali del Gran Sasso (LNGS). CYGNO peculiar features are the use of sCMOS cameras and PMTs coupled to a multiple GEM amplification structure to readout a...

The Deep Underground Neutron Experiment (DUNE) uses a neutrino beam and near detectors at Fermilab and four 10 kilotonne liquid argon Far Detector modules at SURF in South Dakota in order to measure fundamental neutrino properties and to search for supernova neutrinos, nucleon decay, and a plethora of other physics topics. While DUNE's far detectors are powerful tools for studying a wide...

Readout cables for signal sensors are a fundamental component of rare event searches for dark matter and neutrinoless double beta decay. While they possess unique electrical and mechanical properties, polyimide-based flexible cables can be a significant contributor to the total detector background, due to their relatively high content of long-lived primordial radionuclides like 238U and 232Th...

The Deep Underground Neutrino Experiment (DUNE) at the Long-Baseline Neutrino Facility (LBNF) is an international project that will be the largest particle physics experiment ever built in North America. The DUNE project will use massive liquid argon time projection chambers (LArTPCs) to provide insight on fundamental questions such as the origin of the matter/antimatter asymmetry in the...

Achieving detector-grade germanium crystals necessitates employing advanced purification methods to eliminate impurities from standard-grade materials. At the University of South Dakota, we specialize in a meticulous zone refining process tailored to ensure exceptional purity and quality. In this presentation, we delve into the nuances of semiconductor types and provide an overview of how...

Core-collapse supernovae produce neutrinos across all flavors in the range of a few tens of MeV. The integrated flux of these neutrinos forms the diffuse supernova neutrino background (DSNB) or supernova relic neutrinos (SRNs). Their flux, flavor composition, and energy spectrum provide insights into supernova dynamics and star formation. This talk gives a short summary of recent DSNB searches...

This work explores a fascinating oddity in semiconductor dielectric behavior at very low temperatures, with a particular focus on germanium detectors operating at helium temperatures. The relative capacitance rapidly decreases below 11 K and stabilizes at 6.5 K, which is similar to the fully depleted state that was measured at 77.8 K under ambient circumstances. Interestingly, this...

In the standard model of particle physics (SM), the neutrino is an elementary particle that is significantly lighter than other massive particles and can exist in one of three flavor or mass states. Because of this, neutrinos can change states as they undergo a process called neutrino oscillations. Neutrino-oscillation parameters have been measured in many experiments and are mostly consistent...

Presently, there is a significant focus on synthesizing antibacterial nanomaterials for various antibacterial applications, necessitating modifications to the chemical processes involved. In this study, we present the synthesis of chitosan-stabilized calcium peroxide (CCP) nanomaterials (NMs) using a facile precipitation technique with varying reaction temperatures. The crystalline structure...
