Neutron attenuation along the maze of the particle accelerator facility was measured with using activation detectors. Secondary neutrons were generated from a 50cm thick copper target bombarded by 24 GeV protons at CERN/CHARM facility. PHITS Monte Carlo simulation was also performed with modeling the experimental condition, and the simulated result was compared with the measured one.
