“…Our first efforts at evaluating the application potential of C 7 LYC have been to measure both elastic and inelastic neutron scattering cross sections from targets that are identified as high priority by the nuclear data community. We chose to start with the well-studied 56 Fe(n, n ) reaction, and compare our results [13] to recent measurements of the same reaction with traditional tools using TOF techniques [14]. Our experiments were performed at the Weapons Neutron Research facility of the Los Alamos Neutron Science Center, where a white neutron beam with energies up to a few hundred MeV is generated by bombarding a tungsten spallation target with 800 MeV protons.…”

“…The time interval between incident neutron pulses results in a lower cut-off in the neutron energy of ∼ 700 keVee (gamma-or electron-equivalent energy), below which the slowest neutrons of one beam pulse are overtaken by the fastest quanta from the succeeding pulse. The extracted angular distribution results were compared to recent high-resolution measurements in the same energy range [14], using a single arbitrary normalization constant for each energy bin for both elastic and inelastic data. Remarkable agreement is observed in the incident energy range of ∼ 2 to 3 MeV [13], where the intrinsic efficiency has a maximum and is, therefore, approximately flat [11].…”

The scintillator Cs 2 LiYCl 6 (CLYC) has emerged as a versatile detector for both gammas and neutrons, with excellent pulse shape discrimination. Originally developed as a thermal neutron counter, the discovery of its unexpected and unprecedented ∼ 10% pulse height resolution for fast neutrons in the few MeV range has prompted studies to benchmark its use in low-energy nuclear science and applications. Since the typical long time-of-flight arms are not needed for achieving good energy resolution, geometrical efficiency can be enhanced by positioning the detectors much closer to the target. We have constructed a 16-element array of 1" × 1" 7 Li-enriched C 7 LYC, to eliminate the dominant peak in the spectrum from thermal neutron capture on 6 Li, leaving the energy region above 3 MeV with a clean baseline for fast neutron spectroscopy. We have also procured the first ever 3" × 3" C 7 LYC crystal. Test experiments under way with C 7 LYC include elastic and inelastic neutron scattering cross sections at Los Alamos with a pulsed white neutron source, efficiency measurements using mono-energetic neutron beams up to a few MeV at UMass Lowell, and fission neutron measurements with GRETINA and CHICO detector arrays at Argonne. Beta-delayed neutron spectroscopy experiments have also been initiated at the CARIBU and NSCL facilities, to evaluate C 7 LYC as a possible candidate for auxiliary scintillator arrays for stopped beam physics at the next generation rare isotope accelerators.

A spherical-statistical optical model (SOM) has been used to calculate and evaluate the neutron interaction with medium nuclei (40). Empirical formulae of the optical potentials parameters are predicted with minimize accuracy compared with experimental bench work data. With these optical formulae an evaluation of the shape and compound elastic scattering cross-section of interaction neutrons with 56 Fe nuclei at different energy range (1-20) MeV has been calculated and compared with experimental results. Also, volume integrals for real and imaginary potential energies have been evaluated and matched with the standard ABAREX code. Good agreements with have been achieved with the available experimental data.

“…In nuclear and particle physics, fixed-target experiments have been standard practice for studying scattering effects for decades. A particle beam, often with a well-defined energy spectrum, is fired at a target, most commonly perpendicular to the surface normal, although beams with broad spectra and targets with angled surfaces are often studied as well [18]. Detectors sensitive to the scattered incident particles or products of the scattering are used to recover as much information about the scattering as possible.…”

For next-generation neutrinoless double beta decay experiments, extremely low backgrounds are necessary. An understanding of in-situ cosmogenic backgrounds is critical to the design effort. In-situ cosmogenic backgrounds impose a depth requirement and especially impact the choice of host laboratory. Often, simulations are used to understand background effects, and these simulations can have large uncertainties. One way to characterize the systematic uncertainties is to compare unalike simulation programs. In this paper, a suite of neutron simulations with identical geometries and starting parameters have been performed with Geant4 and MCNP, using geometries relevant to the LEGEND-1000 experiment. This study is an important step in gauging the uncertainties of simulations-based estimates. To reduce project risks associated with simulation uncertainties, a novel alternative shield of methane-doped liquid argon is considered in this paper for LEGEND-1000, which could achieve large background reduction without requiring significant modification to the baseline design.
