Times Cited Count:1 Percentile:11.3(Physics, Multidisciplinary)In an antiproton production (Pbar) target station of the Fermi National Accelerator Laboratory (FNAL), the secondary particles produced by bombarding a target with 120-GeV protons are shielded by a thick iron shield. In order to obtain experimental data on high-energy proton accelerator facilities, we indirectly measured 100-MeV neutrons at the outside of the iron shield. The measurement was performed by using the Au activation method coupled with a low-background -ray counting system. As an indicator for the neutron flux, we determined the production rates of 8 spallation nuclides (Au, Pt, Ir, Os, Hf, Lu, Lu, and Yb) in the Au activation detector. The measured production rates were compared with the theoretical production rates calculated using PHITS. We proved that the Au activation method can serve as a powerful tool for indirect measurements of 100-MeV neutrons that play a vital role in neutron transport.

A gold activation detector was studied as a high energy neutron detector at high radiation field in a series of shielding experiment at Fermi National Accelerator Laboratory. We could measure spallation residual nuclei with wide threshold energy by using a combination method with radiological chemical separation and X-X- coincidence detection methods. It was shown the detector was effective for high energy neutron detector.
