Toward high-resolution low-energy electron spectroscopy with transition-edge sensors

Roberto Ammendola, Alice Apponi, G. Benato, Maria Grazia Betti et autres

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 active area of ( 60 × 60 ) μ m 2 …

Tackling the experimental challenge to detect relic neutrinos from the Big Bang with Ptolemy

Federico Virzi

The PTOLEMY project aims to directly detect the Cosmic Neutrino Background radiation exploit- ing the interaction between relic neutrinos and tritium nuclei. The experimental method developed for this purpose is based on the energy measurement of final state electrons produced during the …

PTOLEMY: Relic neutrino direct detection

J. V. Mead, Alice Apponi, Maria Grazia Betti, M. Borghesi et autres

Though their imprint upon the CMB and large-scale structure of the universe remains to this day, Big Bang relic neutrinos (the C𝜈B) have never been directly observed. This remains an outstanding test of the Standard Model in CDM cosmology and would provide …

Searching for Light Dark Matter with Aligned Carbon Nanotubes: The ANDROMeDa Project

Federico Virzi, Alice Apponi, G. Cavoto, Carlo Mariani et autres

The ANDROMeDa (Aligned Nanotube Detector for Research On MeV Dark matter) project aims to develop a novel Dark Matter detector based on carbon nanotubes: the “Dark-PMT”. The detector is designed to be sensitive to dark matter particles with mass between 1 MeV …
