Prospects for precision CENS measurements with electron-capture neutrinos and lithium-based bolometers
Giovanni Benato, Francesca M. Pofi, Andrei Puiu +1
We evaluate the feasibility of high-precision coherent elastic neutrino-nucleus scattering measurements exploiting mono-energetic neutrinos produced by electron-capture (EC) decays…
Towards Low-Energy Electron High-Resolution Spectroscopy with Transition-Edge Sensors
R. Ammendola, A. Apponi, G. Benato +62
We present a study of the energy resolution of transition-edge sensors (TESs) for the detection of electrons in the 100 eV kinetic energy range. The TES is a Ti-Au bilayer with an…
Stability of Highly Hydrogenated Monolayer Graphene in Ultra-High Vacuum and in Air
Alice Apponi, Orlando Castellano, Daniele Paoloni +20
The stability of hydrogenated monolayer graphene was investigated via X-ray photoemission spectroscopy (XPS) for two different environmental conditions: ultra-high vacuum (UHV) and…
Ultra-high precision high voltage system for PTOLEMY
R. Ammendola, A. Apponi, G. Benato +63
The PTOLEMY project is prototyping a novel electromagnetic filter for high-precision spectroscopy, with the ultimate and ambitious long-term goal of detecting the cosmic neutr…
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. Substan…
