“…The determination of the incident neutron energy on the 238 U samples thus relies on the simulation of the inverse kinematics inside the hydrogen gas target, which has been implemented in GEANT4, and a subsequent validation using a neutron TOF measurement at 1.5 meters from the LICORNE source. A cylindrical NE213 liquid scintillation detector from the EDEN array [18] was used to perform such measurements. The neutron spectra seen by the samples were simulated for each inverse kinematics reaction and were validated by a comparison between simulated and measured TOF spectra, see Fig.…”

Prompt-fission γ -ray spectra (PFGS) have been measured for the 238 U(n, f ) reaction using fast neutrons produced by the LICORNE directional neutron source. Fission events were detected with an ionization chamber containing actinide samples placed in the neutron beam, and the coincident prompt-fission γ rays were measured using a number of LaBr 3 scintillation detectors and a cluster of nine phoswich detectors from the PARIS array. Prompt-fission γ rays (PFGs) were discriminated from prompt-fission neutrons using the time-of-flight technique over distances of around 35 cm. PFG emission spectra were measured at two incident neutron energies of 1.9 and 4.8 MeV for 238 U(n, f )andalsofor 252 Cf (sf ) as a reference. Spectral characteristics of PFG emission, such as mean γ multiplicity and average total γ -ray energy per fission, as well as the average γ -ray energy, were extracted. The sensitivity of these results to the width of the time window and the type of spectral unfolding procedure used to correct for the detector responses was studied. Iteration methods were found to be more stable in low-statistics data sets. The measured values at E n = 1.9 MeV were found to be the mean γ multiplicity M γ = 6.54 ± 0.19, total released energy per fission E γ,tot = 5.25 ± 0.20 MeV, and the average γ -ray energy ǫ γ = 0.80 ± 0.04 MeV. Under similar conditions, the values at E n = 4.8 MeV were measured to be M γ = 7.31 ± 0.46, E γ,tot = 6.18 ± 0.65 MeV, and ǫ γ = 0.84 ± 0.11 MeV.

A new time-of-flight array for β-delayed neutron spectroscopy (E n < 5 MeV) is being developed with the aim of improved performance compared to existing arrays. We report on the status of this development, in particular the study of the n-γ discrimination quality with digital electronics, a comparison of several organic scintillators, including new discriminating plastics, as well as the characterisation of detectors with monoenergetic neutrons to measure intrinsic efficiencies and cross-talk probabilities.
