Intermediate and High-Energy Accelerator Shielding Benchmarks

 1. Name of Experiment:
    Intermediate and High-Energy Accelerator Shielding Benchmarks

 2. Purpose and Phenomena Tested:
    Six kinds of Benchmark problems were selected for evaluating the model codes 
    and the nuclear data for the intermediate and high energy accelerator shielding 
    by the Shielding Subcommittee in the Research Committee on Reactor Physics. 
    The benchmark problems contain three kinds of neutron production data from 
    thick targets due to proton, alpha and  electron, and three kinds of shielding 
    data for secondary neutron and photon generated by proton. Neutron and photoneutron 
    reaction cross section data are also provided for neutrons up to 500 MeV and 
    photons up to 300 MeV, respectively.
