[en] One of the main activities of the LMDN laboratory (Laboratory for neutron metrology and dosimetry ) is the development of a technical set of facilities producing neutron yields, in form of mono-energetic or broad yields. The provision of these yields allows the calibration and the development of instruments of measurements devoted to neutrons. The AMANDE facility produces fields of monoenergetic neutrons between 2 keV and 20 MeV with a metrological quality. The facility requires determining in an absolute way, characteristics of energy and fluence of the neutron fields. The development of an instrument allowing a direct measurement of neutron energy and fluence was planned for recognition of this facility as reference. The constituent elements of the system were studied in order to increase the efficiency of the detector in comparison with that of some existing proton recoil telescope. To cover the wide energy range of the produced neutrons, two solutions are investigated. A recoil proton telescope using CMOS sensor (RPT-CMOS) is studied for measurements at the high energies; it is developed in collaboration with the IPHC RAMSES laboratory of Strasbourg. The gaseous μ-time projection chamber for the neutron detection (μ-TPC neutron) will be dedicated to the lowest energies. The study of this device for application at the AMANDE facility is performed in collaboration with the LPSC Grenoble. Simulations of systems and comparisons with the literature were performed with the transport Monte Carlo code MCNPX, to choose the components and the geometry, and thereby assess and optimize efficiency and detection limits of these devices. These computation results are presented. Measurement campaigns were realised during last three years with the first prototypes. Thanks to these, a comparison between experimental results and calculations was enabled, to validate the modelling and to estimate performances expected from these systems. These results are also presented. (author)
