Abstract :
The collection efficiency f for the photoelectrons emitted from a CsI photocathode into CF4 and into Ar-CF4 and Ne-CF4 mixtures is investigated by Monte Carlo simulation The dependence of f on the reduced electric field E/N in the 0.1-40 Td range, on incident photon energy Eph in the 6.8-9.8 eV (183-127 nm) range and on mixture composition is analyzed. Electron drift parameters in CF4, Ar-CF4 and Ne-CF4 are also presented.
