Description
The air fluorescence detection technique is widely used in ultra-high energy cosmic ray experiments to reconstruct the shower cascade profile and determine both the energy and arrival direction of the primary particle. Using the CORSIKA air shower simulation code, the evolution of extensive air showers induced by primary particles with energies reaching up to 100 EeV is modeled, considering various combinations of high- and low-energy hadronic interaction models. The study examines the sensitivity of key parameters, including the longitudinal particle distribution, the depth of the shower maximum, and the energy deposited in the atmosphere, under different simulation conditions. The implications of these findings for UHECR experiments are explored, with a particular focus on a space-based fluorescence telescope aboard the International Space Station. Additionally, the number of fluorescence photons and the timing profile of their arrival at the detector pupil are computed for typical extreme-energy events.
