Abstract

A study of the n-γ discrimination with NE213 and BC501A liquid scintillators, carried out with 40 and 56 MeV neutron beams, reflects different reaction channels involved in the detection process of high energy neutrons. Up to seven different reaction channels were identified in the pulse shape discrimination spectrum measured by a digital charge comparison method. The analysis of the energy spectra of the secondary particles allowed the cross sections for different reaction channels to be estimated as well. This is shown for the important ¹²C(n, d) reaction and the non-negligible contribution of the ¹²C(n, t) reaction to the total efficiency of the NE 213 liquid scintillator for neutrons.

Measurement of neutron energy spectra of 345 MeV/u <sup>238</sup>U incidence on a copper target
2022, Nuclear Instruments and Methods in Physics Research, Section B: Beam Interactions with Materials and Atoms
Thick target neutron yields produced by 345 MeV/u ²³⁸U incidence on a copper target were measured at 0°, 45°, and 90° using liquid organic scintillators and the time-of-flight method. The experimental results were compared with those calculated using the JAERI Quantum Molecular Dynamics (JQMD) model implemented in the Particle and Heavy Ion Transport code System (PHITS) and the G4QMD model in GEometry ANd Tracking 4 (Geant4). The JQMD model reproduced the experimental data better than the G4QMD model at 0°.
Comparison of detectors with pulse shape discrimination capability for simultaneous detection of gamma-rays, slow and fast neutrons

The observed (Fig. 8, bottom-left) poor separation of the thermal neutron peak from the fast neutron components in B-10 loaded scintillators is the effect of quenching of the light pulse slow component derived from the charge particles produced in a capture reaction of thermal neutrons [2,35]. The lack of quenching in the no-boron loaded scintillator was reported in [36], where unambiguous separation was presented for a number of light pulse components reflecting different reaction channels involved in the process of detecting high-energy neutrons in the BC501 A liquid scintillator. The gamma-ray count rates were very similar for all of the detectors, with less than a 20% difference of the lowest yield compared to the highest one.
In this paper, five detectors (EJ-270 — single plastic scintillator, EJ-309B5 — single liquid scintillator, and 3 phoswich detectors: EJ-276+GS20, GS20+EJ-276, EJ-309+GS20) were studied in terms of simultaneous detection of gamma-rays and slow and fast neutrons. The measurements were carried out in a mixed field of neutron and gamma radiation from an intense ( $\sim$ 10⁶ neutrons/s/4 $π$ ) PuBe source. The PuBe neutron source was placed in an 18 cm diameter paraffin ball in order to increase the number of slow neutron detections. This paper covers the measurements of the neutron/gamma discrimination, photoelectron yield and analysis of the light pulse shapes originating from events related to gamma-rays, slow neutrons and fast neutrons. Sensitivity to slow neutrons is also briefly discussed. A comparison of n/ $γ$ discrimination for all of the tested detectors shows excellent performance of all phoswich detectors. Phoswich configurations tested within the scope of this study allow unambiguously resolve all three types of radiation and show superior performance in comparison with single loaded plastic or liquid scintillators.
Measurement of thick target neutron yields from 7 MeV/u α incidence on <sup>209</sup>Bi
2020, Nuclear Instruments and Methods in Physics Research, Section B: Beam Interactions with Materials and Atoms
Thick target neutron yields produced by 7 MeV/u $α$ incidence on a ²⁰⁹Bi target were measured at emission angles of 0 $°$ , 45 $°$ , and 90 $°$ using EJ301 liquid scintillators and the time-of-flight method. The experimental thick target yields were compared with those calculated using the Liège IntraNuclear-Cascade (INCL) and the JAERI Quantum Molecular Dynamics (JQMD) models followed by the Generalized Evaporation Model (GEM) implemented in PHITS. The INCL model successfully reproduced the neutron energy distribution. In contrast, the JQMD model could not reproduce the distribution, even for the reactions induced by low energy composite particles.
Deuterated stilbene (stilbene-d<inf>12</inf>): An improved detector for fast neutrons

Data obtained using the digitizer CI method were somewhat more linear. However, the linearity can depend on several factors including pulse integration times, PMT HV, etc. [12–16] and will be discussed in more detail in [2]. As shown with other deuterated scintillators, this should then allow for the accurate unfolding of the light spectrum to deduce the incident neutron energy spectrum once the detector response functions are known [5,9,15,16,21,22] and room-return neutrons removed as needed.
We have developed and evaluated two prototype fast neutron deuterated-stilbene scintillators. The largest scintillator is hexagonal in shape with volume 32 cm³, comprised of deuterated crystalline trans-stilbene (stilbene-d₁₂). These samples were grown using a solution-based crystal growing method developed at Lawrence Livermore Laboratory to grow conventional ¹H-based stilbene scintillator crystals. The stilbene-d₁₂ prototype detectors show excellent neutron/gamma discrimination, noticeably better than ¹H-stilbene, and appear to have less asymmetry in the response to neutrons incident from different directions. Like other deuterated scintillators, the stilbene-d₁₂ detectors in many applications can provide incident neutron energy spectra, without time of flight, by suitably unfolding the neutron light-output spectra.
Systematic measurement of double-differential neutron production cross sections for deuteron-induced reactions at an incident energy of 102 MeV

In the low energy range (≤15 MeV), the number of background gamma-ray events was comparable to that of neutron events in the measurement with the 5.08 cm detector. Both the events were well separated by PSD using the two gate integration method [25]. In Fig. 3, one of the examples is shown as a two-dimensional plot of the total-gate light output versus the slow-gate one.
Double-differential neutron production cross sections (DDXs) for deuteron-induced reactions on Li, Be, C, Al, Cu, and Nb at 102 MeV were measured at forward angles ≤25° by means of a time of flight (TOF) method with NE213 liquid organic scintillators at the Research Center of Nuclear Physics (RCNP), Osaka University. The experimental DDXs and energy-integrated cross sections were compared with TENDL-2015 data and Particle and Heavy Ion Transport code System (PHITS) calculation using a combination of the KUROTAMA model, the Liege Intra-Nuclear Cascade model, and the generalized evaporation model. The PHITS calculation showed better agreement with the experimental results than TENDL-2015 for all target nuclei, although the shape of the broad peak around 50 MeV was not satisfactorily reproduced by the PHITS calculation.
Response of the Li-7-enriched Cs<inf>2</inf>LiYCl<inf>6</inf>:Ce (CLYC-7) scintillator to 6-60 MeV neutrons

Again, this result is not unexpected given the ratio of observed-to-calculated accidentals at 36.1 and 60.5 MeV and the fact that the rates and amplitudes of the pulses are much lower than at higher energies. The band located between the electron and proton bands is attributed to the neutron-capture protons escaping from the scintillator volume without fully depositing their energy [24]. Similar results have been observed in organic scintillators [25].
We discuss a test campaign designed to irradiate the ⁷Li-enriched Cs₂LiYCl₆:Ce³⁺ (CLYC-7) scintillator with 6–60 MeV neutrons using the cyclotron located at the Crocker Nuclear Laboratory in Davis, CA. CLYC-7 is a newly developed scintillator that exhibits the ability to make good γ-ray measurements and has the ability to detect and discriminate fast neutrons via pulse shape discrimination (PSD) while functioning as a spectrometer. This allows a single detector to make good measurement of both stimuli simultaneously. The response of this scintillation detector has been investigated below 20 MeV [1] but has yet to be explored for energies greater than 20 MeV. Understanding the spectral and pulse shape response across a broad energy range is important for any radiation detection instrumentation capable of detecting multiple species. At the highest energies sampled, the CLYC-7 PSD demonstrated not only the standard electron/proton separation expected in a mixed γ/n field but the ability to discriminate locally produced deuterons, tritons and α particles. We show the results from the four different neutron beam energies sampled during the experiment. Lastly, we present the results obtained for relating the light output equivalence between electrons and protons/deuterons.
