Introduction Made available by U.S. Department of Energy Office of Scientific and Technical Information Abstract The parameters of a neutron detector with the NE213 liquid scintillator which filled teflon cuvettes of long sizes have been investigated. It is shown that light attenuation effects are considerably weaker for the teflon cuvette as compared to the glass cells with an “external” reflector. The value λ = 7–10 m has been obtained for the light absorption length in the NE213 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.

Characterization of a NE-213 liquid scintillator for neutron ux measurement at JET Federico Binda Uppsala University, Sweden March, 2011 Abstract The measurment of the total neutron rate from a nuclear fusion reactor is very important in order to calculate the power produced in a plasma.

An improvement of a method currently in use at JET 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.

Pions having energies up to 60 MeV were clearly discriminated from protons and electrons. 2005-01-01 1989-08-20 · Choice scintillator We have chosen the NE213 liquid scintillator for its very good gamma-neutron pulse-shape discrimination (PSD) characteristics.

It is a solution of aromatic molecules suspended in a xylene solvent. 1 The result is a flammable, corrosive, sharp-smelling liquid with a flash point of ∼ 26 ° C that poses a considerable health risk. 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.
