A complete optical model for liquid-scintillator detectors

Antineutrino geophysics with liquid scintillator detectors

Detecting the antineutrinos emitted by the decay of radioactive elements in the mantle and crust could provide a direct measurement of the total abundance of uranium and thorium in the Earth. In calculating the antineutrino flux at specific sites, the local geology of the crust and the background from the world’s nuclear power reactors are important considerations. Employing a global crustal ma...

How to observe B solar neutrinos in liquid scintillator detectors

We show that liquid organic scintillator detectors (e. g., KamLAND and Borexino) can measure the 8B solar neutrino flux by means of the νe charged current interaction with the 13C nuclei naturally contained in the scintillators. The neutrino events can be identified by exploiting the time and space coincidence with the subsequent decay of the produced 13N nuclei. We perform a detailed analysis ...

Optical simulation of monolithic scintillator detectors using GATE/GEANT4.

Much research is being conducted on position-sensitive scintillation detectors for medical imaging, particularly for emission tomography. Monte Carlo simulations play an essential role in many of these research activities. As the scintillation process, the transport of scintillation photons through the crystal(s), and the conversion of these photons into electronic signals each have a major inf...

Short-baseline neutrino oscillation waves in ultra-large liquid scintillator detectors

Powerful new multi-kiloton liquid scintillator neutrino detectors, including NOνA and LENA, will come on-line within the next decade. When these are coupled with a modest-power decay-at-rest (DAR) neutrino source at short-baseline, these detectors can decisively address the recent ambiguous signals for neutrino oscillations at high ∆m. These detectors are > 50 m long, and so with a DAR beam, th...
