In this paper, we present the results obtained from the data analysis of neutron spectra measured with a NE213 liquid scintillator at JET. We calculated the neutron response matrix of the instrument combining MCNPX simulations, a generic proton light output function measured with another detector and the fit of data from ohmic pulses.

Liquid scintillation counting is the measurement of radioactive activity of a sample material which uses the technique of mixing the active material with a liquid scintillator (e.g. zinc sulfide), and counting the resultant photon emissions.

2015-02-13 · In particular, the capabilities of the two fast neutron detectors to discriminate between neutrons and gamma-rays were investigated. The NE-213 liquid-scintillator reference cell produced a wide range of scintillation-light yields in response to the gamma-ray field of the source. Particles emitted from spallation reactions induced by protons having GeV energies were measured with an NE213 liquid scintillator, 12.7 cm in diameter and 12.7 cm thick. The pulse‐shape discrimination (PSD) was carried out for charged particle identification by the two‐gate integration method.

The goal of the work presented in this thesis is to estimate to which extent a compact detector such as a NE213 liquid scintillator can be used to perform neutron emission spectroscopy analysis. The detector used for this study was installed in the back of the MPRu spec- trometer at JET in 2012. An organic liquid scintillator, such as NE213 and BC501A, is widely used for neutron spectrum measurement behind a shield by coupling with the unfolding technique, because it has a high detection efficiency, good neutron–photon discrimination performance and comparably good energy resolution. In this work we present a method to evaluate the neutron response function of an NE213 liquid scintillator.

The measurements have been performed on candidate mixtures for the low energy solar neutrino detector Borexino, as well as on the standard NE213 scintillator, specifically optimized for the PSD application. The description of the results will be complemented by a comparison of the characterization obtained with the two different methods.
