First measurement of GaAs as a scintillating calorimeter: achievements and prospects
A. Melchiorre, D. L. Helis, A. Puiu +23
In this paper we present the first measurement of a Gallium Arsenide (GaAs) crystal as a scintillating calorimeter with dual heat and light readout within the DAREDEVIL project. Th…
A Demonstration of Slowed Electron Drift for PTOLEMY
M. Farino, A. Tan, A. Apponi +58
To resolve the effective neutrino mass with an energy resolution of 50~meV, the PTOLEMY experiment has proposed a novel transverse electromagnetic filtering process. Substant…
Detection of Low-Energy Electrons with Transition-Edge Sensors
Carlo Pepe, Benedetta Corcione, Francesco Pandolfi +9
We present the first detection of electrons with kinetic energy in the 100 eV range with transition-edge sensors (TESs). This has been achieved with a m Ti…
Dark counts in optical superconducting transition-edge sensors for rare-event searches
Laura Manenti, Carlo Pepe, Isaac Sarnoff +12
Superconducting transition-edge sensors (TESs) are a type of quantum sensor known for its high single-photon detection efficiency and low background. This makes them ideal for part…
Implementation and Optimization of the PTOLEMY Transverse Drift Electromagnetic Filter
A. Apponi, M. G. Betti, M. Borghesi +53
The PTOLEMY transverse drift filter is a new concept to enable precision analysis of the energy spectrum of electrons near the tritium beta-decay endpoint. This paper details the i…
PTOLEMY: A Proposal for Thermal Relic Detection of Massive Neutrinos and Directional Detection of MeV Dark Matter
E. Baracchini, M. G. Betti, M. Biasotti +48
We propose to achieve the proof-of-principle of the PTOLEMY project to directly detect the Cosmic Neutrino Background (CNB). Each of the technological challenges described in [1,2]…
Thermal analysis of Josephson junctions array in cryocooler
P. Durandetto, E. Monticone, B. Trinchera +4
Complex cryogenics is still a strong limitation to the spread of quantum voltage standards and cryogen-free operation is then particularly interesting for Josephson standards. The…
High intrinsic energy resolution photon number resolving detectors
L. Lolli, E. Taralli, C. Portesi +2
Transition Edge Sensors (TESs) are characterized by the intrinsic figure of merit to resolve both the energy and the statistical distribution of the incident photons. These propert…
