  • Abstract
    The collection efficiency f for the photoelectrons emitted from a CsI photocathode into Xe-CH4 mixtures, for incident photons Eph in the 6.8-9.8 eV (183-127 nm) energy range and applied electric fields from E/N = 0.1 Td to E/N = 40 Td is investigated by Monte Carlo simulation, following a previous study in CH4 and Ar-CH4 mixtures. The dependence of f on the reduced electric field E/N, incident photon energy Eph and mixture composition is analyzed. To test the electron scattering cross-sections used in the simulation, electron drift parameters in Xe and Xe-CH4 mixtures are calculated and compared with available experimental data.
