Measurements of the Quantum Yield of Silicon using Geiger-mode Avalanching Photodetectors

Autor: Lewis, Harry, Mahtab, Mahsa, Retiere, Fabrice, Croix, Austin De St., Raymond, Kurtis, Henriksson-Ward, Maia, Morrison, Nicholas, Zhang, Aileen, Capra, Andrea, Underwood, Ryan

Accurate characterization of quantum yield is crucial to the reconstruction of energy depositions in silicon at the eV scale. This work presents a new method for experimentally calculating quantum yield using vacuum UV-sensitive silicon photomultipli

Turbulent Energy Conversion Associated with Kinetic Microinstabilities in Earth's Magnetosheath

Autor: Lewis, Harry C., Stawarz, Julia E., Matteini, Lorenzo, Franci, Luca, Klein, Kristopher G., Wicks, Robert T., Salem, Chadi S., Horbury, Timothy S., Wang, Joseph H.

Plasma in the terrestrial magnetosheath is characterised by very weak particle-particle collisions, so kinetic microinstabilities are thought to be responsible for regulating the thermodynamics of the plasma. By exciting electromagnetic waves, these

Stimulated Secondary Emission of Single Photon Avalanche Diodes

Autor: Raymond, Kurtis, Retière, Fabrice, Lewis, Harry, Capra, Andrea, McCarthy, Duncan, Croix, Austin de St, Gallina, Giacomo, McLaughlin, Joe, Martin, Juliette, Massacret, Nicolas, Agnes, Paolo, Underwood, Ryan, Koulosousas, Seraphim, Margetak, Peter

Large-area next-generation physics experiments rely on using Silicon Photo-Multiplier (SiPM) devices to detect single photons, which trigger charge avalanches. The noise mechanism of external cross-talk occurs when secondary photons produced during a
