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…
Absolute efficiency of a two-stage microchannel plate for electrons in the 30 - 900 eV energy range
A. Apponi, F. Pandolfi, I. Rago +3
We report on an apparatus able to measure the absolute detection efficiency of a detector for electrons in the 30 - 900 eV range. In particular, we discuss the characterisation of…
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…
Response of Windowless Silicon Avalanche Photo-Diodes to Electrons in the 90-900 eV Range
Alice Apponi, Gianluca Cavoto, Marco Iannone +5
We report on the characterization of the response of windowless silicon avalanche photo-diodes to electrons in the 90-900 eV energy range. The electrons were provided by a monoener…
Carbon nanotubes as anisotropic target for dark matter
G Cavoto, M G Betti, C Mariani +4
Directional detection of Dark Matter (DM) particles could be accomplished by studying either ion or electron recoils in large arrays of parallel carbon nanotubes. For instance, a M…
