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 neutri…
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…
A Wide Optical-Gap in Fully -Like Hydrogenated Monolayer Graphene
Alice Apponi, Orlando Castellano, Daniele Paoloni +5
A comprehensive spectroscopic characterisation of two highly hydrogenated monolayer graphene samples transferred onto nickel grids is reported. With X ray photoemission spectroscop…
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…
