A NE213 liquid scintillator, neutron detector designed for lifetime measurements of very neutron-rich nuclei Pulse-shape discrimination in NE213 liquid scintillator detectors January 2012 Nuclear Instruments and Methods in Physics Research Section A Accelerators Spectrometers Detectors and Associated In this work we present a method to evaluate the neutron response function of an NE213 liquid scintillator. This method is particularly useful when the proton light yield function of the detector has not been measured, since it is based on a proton light yield function taken from literature, MCNPX simulations, measurements of gamma-rays from a calibration source and measurements of neutrons It is identical to the widely reported NE-213 and exhibits all of the properties of that scintillator. EJ-309 has been developed as an alternate to the more commonly used low-flash point PSD liquid scintillators based on the solvent xylene. NE213 organic scintillator detectors are widely used for the measurements of neutron energy spectrum in mixed neutron-gamma fields due to their pulse shape discrimination properties. 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.

The activation function and the connectivity of the neurons have been through the scintillator wall induced by high-energy neutrons increase from 6% for 66MeV neutrons to 35% for 206MeV neutrons, and that this wall eﬀect causes a diﬃcult problem for n g discrimination. 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. Pions having energies up to 60 MeV were clearly discriminated from protons and electrons.
