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 this study, a large sample of cosmic muons is identified and tracked by a muon veto detector external to the liquid scintillator, and by the specific light patterns observed when muons cross the scint...
متن کاملMuon 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 signals requires a strong suppression of backgrounds below a few MeV. Very low intrinsic radiogenic contamination of all detector components needs to be accompanied by the efficient identification of ...
متن کاملA measurement of the muon-induced neutron yield in lead at a depth of 2850 m water equivalent
We present results from the measurement of the neutron production rate in lead by high energy cosmic-ray muons at a depth of 2850 m water equivalent (mean muon energy of 260 GeV). A tonne-scale highly segmented plastic scintillator detector was utilised to detect both the energy depositions from the traversing muons as well as the delayed radiative capture signals of the induced neutrons. Compl...
متن کاملCardiovascular System Response to Carbon Dioxide and Exercise in Oxygen-Enriched Environment at 3800 m
BACKGROUND This study explores the responses of the cardiovascular system as humans exercise in an oxygen-enriched room at high altitude under various concentrations of CO₂. METHODS The study utilized a hypobaric chamber set to the following specifications: 3800 m altitude with 25% O₂ and different CO₂ concentrations of 0.5% (C1), 3.0% (C2) and 5.0% (C3). Subjects exercised for 3 min three ti...
متن کاملEquivalent Volume Sources for Explosions at Depth: Theory and Observations
For simple theoretical models of an underground explosion, two apparently different relationships between isotropic moment and volume change have been published. We show that there is no inconsistency, because these relationships are based on two different definitions of volume change at the explosion source. We report observations of three 25-ton chemical explosions conducted in 1997 at the fo...
