Carbon Nanostructures for Dark Matter Detection

Francesco Pandolfi (CERN-ETH)


Carbon nanostructures offer exciting new possibilities in the development of new particle detectors. Graphene is a 2-dimensional material, therefore a Dark Matter particle with mass between 1 MeV and 1 GeV can eject an electron from the Carbon lattice directly into the vacuum. We will report on the development, within the framework of the PTOLEMY experiment, of novel directional light dark matter detectors based on carbon nanostructures: 'Graphene-FETs', and 'Dark-PMTs'. We will also report on the new carbon-nanotube growing facility recently built in University 'Sapienza' of Rome.
