Neutron Background Mitigation
- Sean Paling
Neutron-induced backgrounds pose a significant challenge in experiments designed to detect rare events, such as dark matter interactions and neutrinoless double-beta decay. This talk discusses the characteristics of these backgrounds, focusing on neutron generation via spontaneous fission and α,n reactions. These processes are particularly critical in underground experiments, where the...
The sensitivity of underground experiments searching for rare events such as dark matter, neutrinoless double-beta decay or low-energy neutrinos is affected by the background due to neutrons from spontaneous fission and (α,n) reactions. Neutron yields and energy spectra due to these reactions can be calculated using a variety of codes. In this paper we present new calculations of neutron...
In rare events experiments, a precise knowledge of the environmental gamma and neutron backgrounds is crucial for the design of appropriate shieldings. The neutron component is often poorly known due to the lack of a scalable detector technology for the measurement of low-flux neutron spectra in a short time.
Thanks to their high gadolinium content, we are investigating the possibility of...
