Abstract

An Atmospheric Neutron Irradiation Spectrometer (ANIS) with a neutron spectrum resembling that of atmospheric neutrons was physically designed at the China Spallation Neutron Source (CSNS). The general layout and the main components of ANIS are presented and discussed. The beam specifications including the atmospheric neutron spectrum, neutron flux, beam spot and beam uniformity are obtained via Monte Carlo simulations. Charged particles and photons were also analyzed. Simulation results indicate that ANIS is a world-class neutron irradiation facility based on proton accelerator, with very distinctive neutron beam quality and wide range adjustment capability. The first neutron beam will be supplied in the end of 2021. It will supply a powerful platform for the accelerated Single Event Effect (SEE) test that is used in aviation and terrestrial electronics, in compliance with the requirements of the associated international standards.
