SINBAD ABSTRACT NEA-1552/33
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.
