21. Neutron capture on Cr for criticality safety via time-of-flight at CERN n_TOF and activation at CNA HiSPANoS with 30 and 90 KeV quasi-Maxwellian spectra

The NEA High priority Request List [Plompen:2007] features the neutron capture on 50Cr and 53Cr between 1 and 100 keV as very relevant for criticality safety. In the case of 50Cr, the product of the (n,γ) reaction is 51Cr, unstable with a half-life of 27.7 days which makes it suitable for neutron activation experiments. Although several time-of- flight experiments have been performed,...

11. Effects of MgF2 on neutrons along the keV energy range and study of the neutron capture on fluorine.

The main goal of this proposed experiment is to study the interaction of neutrons with magnesium fluoride (MgF2). These neutrons are produced at MONNET in the Joint Research Centre-European Comission at Geel, Belgium, using a lithium fluoride target (LiF), via 7Li(p,n) reaction. There are three main goals for the experiment:
1.-Characterization of the angular and energetic distribution of the...

16. Neutron characterization of scintillators for neutron metrology from 100 keV to 22 MeV

The Laboratory for micro-irradiation, neutron metrology and dosimetry (LMDN) is responsible for establishing metrological references in France for neutron fluence energy distributions and associated dosimetric quantities. The LMDN has acquired four 2"x2" scintillators for these metrological purposes; two stilbenes and two EJ309. The aim of this work is to characterize these scintillators,...
