“…Our result and the other recent measurements [3,5,[7][8][9] are about 10% higher than the expectations obtained with FLUKA. For the results reported before 1990 [4,6,10], the neutron yields are 30% to 40% higher than the predictions. The disagreement between the experimental results and predictions is insensitive to the energy distribution of the underground muons used in the simulation [27].…”

“…), the Borexino experiment [9] (depth 3800 m.w.e. ), and the Liquid Scintillation Detector (LSD) in Mont Blanc [10] (depth 5200 m.w.e.). For the measurement results, the abscissa corresponds to the average muon energy at the experimental depth.…”

“…There are nine measurements on the production of muon-induced neutrons in an organic liquid scintillator at various depths, ranging from 20 to 5200 m water equivalent (m.w.e.) [3][4][5][6][7][8][9][10]. In general, such measurements require detailed and experiment-specific Monte Carlo simulations to correct for the neutron contribution from rock as well as the metallic components of the detectors, but this is difficult, especially for the older experiments like those in Refs.…”

We have measured the muon flux and production rate of muon-induced neutrons at a depth of 611 m water equivalent. Our apparatus comprises three layers of crossed plastic scintillator hodoscopes for tracking the incident cosmic-ray muons and 760 L of gadolinium-doped liquid scintillator for producing and detecting neutrons. The vertical muon intensity was measured to be Iµ = (5.7±0.6)× 10 −6 cm −2 s −1 sr −1 . The yield of muon-induced neutrons in the liquid scintillator was determined to be Yn = (1.19 ± 0.08(stat) ± 0.21(syst)) × 10 −4 neutrons/(µ·g·cm −2 ). A fit to the recently measured neutron yields at different depths gave a mean muon energy dependence of Eµ 0.76±0.03 for liquid-scintillator targets.

“…While the first process is well understood, the second is poorly known. Although the total neutron yield from muon spallation has been, to some extent, experimentally measured [8,9], theoretical models [10][11][12] are not consistent with each other and with data. In addition the few measurements of the neutron energy spectrum [13] are not well reproduced by theoretical calculations [14,15].…”

New approach to background subtraction in low-energy neutrino experiments

We discuss a new method to extract neutrino signals in low energy experiments. In this scheme the symmetric nature of most backgrounds allows for direct cancellation from data. The application of this technique to the Palo Verde reactor neutrino oscillation experiment allowed us to reduce the measurement errors on the anti-neutrino flux from ∼ 20% to ∼ 10%. We expect this method to substantially improve the data quality in future low background experiments such as KamLAND and LENS.
