نویسندگان
چکیده
This paper describes the liquid scintillator veto system for COSINE-100 dark matter experiment and its performance. The detector consists of eight NaI(Tl) crystals immersed in 2200~L linear alkylbenzene-based scintillator. tags between 65 75\% internal $^{40}$K background 2--6 keV energy region. We also describe model scintillator, which is primarily used to assess calibration threshold.

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...
متن کاملThe liquid scintillator neutrino detector and LAMPF neutrino source
A search for neutrino oscillations of the type F& + V, has been conducted at the Los Alamos Meson Physics Facility using F, from muon decay at rest. Evidence for this transition has been reported previously. This paper discusses in detail the experimental setup, detector operation and neutrino source, including aspects relevant to oscillation searches in the muon decay-at-rest and pion decay in...
متن کاملCalibration of BC501A liquid scintillator cells with monochromatic neutron beams
The recoil proton energy response has been measured by exposing cylindrical cells, filled with BC501A BICRON liquid scintillator, to mono-energetic neutron reference fields. We determine the required calibration parameters and report the detailed procedures for the experimental data handling. A dedicated Montecarlo simulation has successfully been used to check the consistency of the experiment...
متن کاملDetecting energy dependent neutron capture distributions in a liquid scintillator
A novel technique is being developed to estimate the effective dose of a neutron field based on the distribution of neutron captures in a scintillator. Using Monte Carlo techniques, a number of monoenergetic neutron source energies and locations were modelled and their neutron capture response was recorded. Using back propagation Artificial Neural Networks (ANN) the energy and incident directio...
متن کاملReactor Neutrino Experiments with a Large Liquid Scintillator Detector
We discuss several new ideas for reactor neutrino oscillation experiments with a Large Liquid Scintillator Detector. We consider two different scenarios for a measurement of the small mixing angle θ13 with a mobile ν̄e source: a nuclear-powered ship, such as a submarine or an icebreaker, and a land-based scenario with a mobile reactor. The former setup can achieve a sensitivity to sin 2θ13 . 0.0...
