This study explores the feasibility of using Cherenkov Telescope Array (CTA) technology to detect ultra-high-energy (UHE) neutrino tau particles. By analyzing the Cherenkov radiation emitted by charged particles produced through neutrino tau interactions within mountainous terrains, the work evaluates the potential for detecting neutrinos in the 1016–1018 eV energy range. The methodology includes calculating the effective detection area and the interaction probabilities of tau neutrinos within rock, along with estimating the resulting Cherenkov photon flux generated by emerging tau leptons. Additionally, the study identifies optimal parameters for telescope placement, such as mountain size, telescope elevation, spacing between units, and the distance from the mountain to the array. Strategic positioning of telescopes and selection of favorable mountain configurations are proposed to maximize sensitivity. The results provide recommendations for the optimal deployment of telescopes to enhance the detection capabilities for UHE neutrino tau events.
