Development of A Web Toolkit for Calculating $(\alpha,n)$ Induced Neutron Yield and Energy Spectrum

ORAL

Abstract

Neutrons from $(\alpha, n)$ reactions induced by natural radioactivity are important sources of background for low-background experiments such as direct detection of dark matter and neutrinos. A web toolkit has been built for calculating $(\alpha, n)$ neutron yield and neutron energy spectrum induced by $^{238}U$, $^{232}Th$ and Sm decays in all possible elements or compound. We describe the web toolkit that offers neutron yield and energy spectrum in terms of customized input.
