| 英文摘要 | The china spallation neutron source (csns) will accommodate 20 neutron beamlines at its first target station. these beamlines serve different purposes, and beamline 11 is designed to analyze the degraded models and damage mechanisms, such as single event effects in electronic components and devices for aerospace electronic systems. this paper gives a preliminary discussion on the scheme of a high energy neutron irradiation experiment at the beamline 11 shutter based on the monte carlo simulation method. the neutron source term is generated by calculating the neutrons scattering into beamline 11 with a model that includes the target-moderator-reflector area. then, the neutron spectrum at the sample position is obtained. the intensity of neutrons with energy of hundreds of mev is approximately 1e8 neutron/cm(2)/s, which is useful for experiments. the displacement production rate and gas productions are calculated for common materials such as tungsten, tantalum and ss316. the results indicate that the experiment can provide irradiation dose rate ranges from 1e-5 to 1e-4 dpa per operating year. the residual radioactivity is also calculated for regular maintenance work. these results give the basic reference for the experimental design.
