    Geant4 simulation of a conceptual calorimeter based on secondary electron emission
    (Iop Publishing Ltd, 2017) Ozok, F.; Yetkin, T.; Yetkin, Elif Aslı; Iren, E.; Erduran, M. N.
    We present a conceptual sampling electromagnetic calorimeter based on secondary electron emission process. The secondary electron emission process was implemented in Geant4 as a user physics class, which accurately reproduces the energy spectrum and yield of secondary electrons for thin metals. The simulation results for the response linearity and energy resolution are compared with that of a scintillation calorimeter. The response and energy resolution of the calorimeter were obtained for electron energies up to 50 GeV. The response linearity to electromagnetic showers is to within 1.5%, whereas the energy resolution is sigma/E = (44%) GeV1/2/root E for 2.5 cm sampling of iron absorber.

    Simulation of secondary emission calorimeter for future colliders
    (Iop Publishing Ltd, 2018) Yetkin, Elif Aslı; Yetkin, T.; Ozok, F.; Iren, E.; Erduran, M. N.
    We present updated results from a simulation study of a conceptual sampling electromagnetic calorimeter based on secondary electron emission process. We implemented the secondary electron emission process in Geant4 as a user physics list and produced the energy spectrum and yield of secondary electrons. The energy resolution of the SEE calorimeter was sigma/E = (41%) GeV1/2/root E and the response linearity to electromagnetic showers was to within 1.5%. The simulation results were also compared with a traditional scintillator calorimeter.
