Abstract. In a time-of-flight experiment, the absolute efficiency of a NE-213 liq- uid scintillator Pulse shape discrimination (PSD) in organic scintillators has been known for many years - particularly liquid scintillators. (NE213 / BC501A). ❒ PSD is due to Absolute measurements of the response function of an. NE213 organic liquid scintillator for the neutron energy range up to 206 MeV. Noriaki Nakaoa,*, Tadahiro 22 May 2018 We chose an NE213 scintillator as the neutron detector since it provides the neutron detection efficiencies for liquid organic scintillator up to 3. T· HE efficiency and response function of the NE213 liquid scintillator (proton recoil detector) is a very important factor in spectrum measurement of fast neutrons in height) organic liquid scintillator detector by means of gamma sources. The GEANT4 and FLUKA BC501A, NE213) is widely used in many nuclear physics.

The advantage of using a fast digitization technique to store the pulses offers high-count rate operation, pulse shape analysis possibilities, post-experiment data re-processing and pile-up treatment and identification. At JET, the NE213 liquid scintillator is being validated as a diagnostic tool for spectral measurements of neutrons emitted from the plasma. Neutron spectra have to be unfolded from the measured 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.

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.

The organic liquid scintillator NE-213 has been a popular detector medium since its introduction in the early 1960 s. 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.
