The construction of the Agua Negra tunnels that will link Argentina and Chile under the Andes, the world longest mountain range, opens the possibility to build the first deep underground laboratory in the Southern Hemisphere. This laboratory has the acronym ANDES (Agua Negra Deep Experiment Site) and its overburden could be as large as ∼ 1.7 km of rock, or 4500 mwe, providing an excellent low background environment to study physics of rare events like the ones induced by neutrinos and/or dark matter. In this paper we investigate the physics potential of a few kiloton size liquid scintillator detector, which could be constructed in the ANDES laboratory as one of its possible scientific programs. In particular, we evaluate the impact of such a detector for the studies of geoneutrinos and galactic supernova neutrinos assuming a fiducial volume of 3 kilotons as a reference size. We emphasize the complementary roles of such a detector to the ones in the Northern Hemisphere neutrino facilities through some advantages due to its geographical location.

“…Only little information on the external background in the three large LNGS halls A, B, and C is available, and there is no published data on the background in the interferometer tunnel, where several experiments are located. Therefore we have measured the background in halls A and B, in the interferometer tunnel, and inside the LVD detector [1]. It was recently suggested that LVD could be used as a very efficient muon shield, effectively increasing the LNGS depth [2].…”

The gamma background flux below 3000 keV in the Laboratori Nazionali del Gran Sasso (LNGS), Italy, has been measured using a 3" diameter NaI(Tl) detector at different underground positions: In hall A, hall B, the interferometer tunnel, and inside the Large Volume Detector (LVD). The integrated flux is 0.3-0.4 s −1 cm −2 at the first three locations, and is lower by two orders of magnitude inside LVD. With the help of Monte Carlo simulations for every location, the contribution of the individual primordial isotopes to the background has been determined. Using an 11" diameter NaI(Tl) detector, the background neutron flux in the LNGS interferometer tunnel has been estimated. Within the uncertainties, the result agrees with those from other neutron measurements in the main halls.

Realistic Earth matter effects and a method to acquire information about smallθ13in the detection of supernova neutrinos

2009

In this paper, we first calculate the realistic Earth matter effects in the detection of type II supernova neutrinos at the Daya Bay reactor neutrino experiment which is currently under construction. It is found that the Earth matter effects depend on the neutrino incident angle θ, the neutrino mass hierarchy ∆m 2 31 , the crossing probability at the high resonance region inside the supernova, PH , the neutrino temperature, Tα, and the pinching parameter in the neutrino spectrum, ηα. We also take into account the collective effects due to neutrino-neutrino interactions inside the supernova. With the expression for the dependence of PH on the neutrino mixing angle θ13, we obtain the relations between θ13 and the event numbers for various reaction channels of supernova neutrinos. Using these relations, we propose a possible method to acquire information about θ13 smaller than 1.5• . Such a sensitivity cannot yet be achieved by the Daya Bay reactor neutrino experiment which has a sensitivity of the order of θ13 ∼ 3• . Furthermore, we apply this method to other neutrino experiments, i.e. Super-K, SNO, KamLAND, LVD, MinBooNE, Borexino, and Double-Chooz. We also study the energy spectra of the differential event numbers, dN/dE.
