“…Liquid-scintillator detectors such as the KamLAND (Kamioka liquid-scintillator antineutrino detector), Borexino [1][2][3], CANDLES IV (calcium fluoride for studies of neutrino and dark matters by low-energy spectrometer) [4,5], SNO+ (Sudbury Neutrino Observatory) [6,7], LENS (low-energy neutrino spectroscopy) [8], and LENA (low-energy neutrino astronomy) [9] are designed to detect low-energy phenomena. In an organic liquid scintillator (LS), energetic muons and subsequent showers interact mostly with 12 C, the most abundant nucleus heavier than 1 H in the LS, generating neutrons and isotopes by electromagnetic or hadronic processes.…”

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 of cosmogenic backgrounds is particularly important for future experiments aiming to determine the pep and CNO solar neutrino fluxes, for which the background is dominated by the spallation production of 11 C. Data from the Kamioka liquid-scintillator antineutrino detector (KamLAND) provides valuable information for better understanding these backgrounds, especially in liquid scintillators, and for checking estimates from current simulations based upon MUSIC, FLUKA, and GEANT4. Using the time correlation between detected muons and neutron captures, the neutron production yield in the KamLAND liquid scintillator is measured to be Y n = (2.8 ± 0.3) × 10 −4 µ −1 g −1 cm 2 . For other isotopes, the production yield is determined from the observed time correlation related to known isotope lifetimes. We find some yields are inconsistent with extrapolations based on an accelerator muon beam experiment.

“…In the future, there are several plans of geoneutrino detectors at different locations; the SNO+ detector close to completing the construction in Canada [Chen 2006], the JUNO detector in China [Han et al 2016], the LENA detector in Europe [Wurm et al 2012], and the movable Hanohano detector in a deep ocean [Learned et al 2008]. Those detectors will have LS mass larger than KamLAND, so we expect the reduction of the statistical uncertainties on the measured o the geo o − e contribution from the mantle is only about one fourth of the total geo o − e flux, and may be estimated based on the subtraction of the crustal contribution depending on the crustal model.…”

“…SNO+ at Sudbury mine in Canada [Chen 2006], having 1000 tons of target, is almost ready to start data taking. The site is located on an old continental crust and the signal from reactor anti-neutrinos is about twice as that at Gran Sasso.…”
