  journal={arXiv: Instrumentation and Methods for Astrophysics},
Cosmic muon interactions are important contributors to backgrounds in underground detectors when searching for rare events. Typically neutrons dominate this background as they are particularly dicult to shield and detect in a veto system. Since actual background data is sparse and not well documented, simulation studies must be used to design shields and predict background rates. This means that valida- tion of any simulation code is necessary to assure reliable results. This work studies the… 

Cosmogenic Backgrounds in Borexino at 3800 m water-equivalent depth

The solar neutrino experiment Borexino, which is located in the Gran Sasso underground laboratories, is in a unique position to study muon-induced backgrounds in an organic liquid scintillator. In

The DarkSide Multiton Detector for the Direct Dark Matter Search

Although the existence of dark matter is supported by many evidences, based on astrophysical measurements, its nature is still completely unknown. One major candidate is represented by weakly

Role of Magnesium in Ultra-Low-Radioactive Titanium Production for Future Direct Dark Matter Search Detectors

Ultra-low-radioactive titanium is the main perspective material for cryostat fabrication in dark matter search experiments. The pathways of the uranium and thorium contamination of Ti sponges

Hybrid Ultra-Low-Radioactive Material for Protecting Dark Matter Detector from Background Neutrons

A laboratory technology for a new ultra-low background hybrid material (HM) which meets the requirements for neutron absorption with simultaneous neutron detection has been developed and can be useful for future low background underground detectors designed to directly search for dark matter with liquid noble gases.

First measurement of pp neutrinos in real time in the Borexino detector

The Sun is fueled by a series of nuclear reactions that produce the energy that makes it shine. Neutrinos (ν) produced by these nuclear reactions exit the Sun and reach Earth within minutes,

Neutron- and muon-induced background in underground physics experiments

Abstract.Background induced by neutrons in deep underground laboratories is a critical issue for all experiments looking for rare events, such as dark matter interactions or neutrinoless ββ decay.

Neutron Background Studies for the CRESST Dark Matter Experiment

The new detection concept applied for the direct WIMP search experiment CRESST II, which enables a clear discrimination between electron recoils and nuclear recoils, will leave neutrons as the main

Predicting neutron production from cosmic ray muons

Fast neutrons from cosmic-ray muons are an important background to underground low-energy experiments. The estimate of such a background is often hampered by the difficulty of measuring and

Muon-induced background study for underground laboratories

We provide a comprehensive study of the cosmic-ray muon flux and induced activity as a function of overburden along with a convenient parametrization of the salient fluxes and differential

Neutrons from muons underground

Results of many-year experimental investigations of neutrons originating from cosmic-ray muons at depths of 25, 316, 570, 3650, and 5200 mwe are presented. Mechanisms of neutron generation by muons

Muon and cosmogenic neutron detection in Borexino

Borexino, a liquid scintillator detector at LNGS, is designed for the detection of neutrinos and antineutrinos from the Sun, supernovae, nuclear reactors, and the Earth. The feeble nature of these

Production of radioactive isotopes through cosmic muon spallation in KamLAND

Radioactive isotopes produced through cosmic muon spallation are a background for rare-event detection in ν detectors, double-β-decay experiments, and dark-matter searches. Understanding the nature

A Highly Efficient Neutron Veto Using Boron‐Loaded Liquid Scintillator

By surrounding a dark matter detector with a layer of boron‐loaded liquid scintillator, a highly efficient neutron veto can be produced. In Monte Carlo studies, a one meter thick layer of

High statistics measurement of the underground muon pair separation at Gran Sasso
