Description
Neutron monitors (NMs) play a crucial role in studying cosmic-ray interactions and atmospheric neutron cascades. However, their response to high-energy neutrons (above 20 MeV) remains uncertain due to the limited availability of neutron cross-section data in simulation frameworks such as GEANT4. This study aims to evaluate the energy sensitivity of a neutron monitor using Monte Carlo techniques, focusing on its differential energy and directional response. By analyzing the contributions of thermal, epithermal, and fast neutrons, produced within atmospheric cascades, we assess the limitations of current response models. Understanding these factors is essential for improving the applicability of neutron monitor data and the neutron monitor response function.
