“…The AMANDE facility of the Institute for radiological protection and nuclear safety (IRSN) at Cadarache is able to produce continuous or pulsed monoenergetic neutrons from ~2 keV up to 20 MeV [3]. The neutron field for this work was produced using the 7 Li(p,n) reaction with a proton beam of 2067 keV energy and 1 µA intensity sent on a LiF target of 107 µg/cm² thickness.…”

The results of experiments performed with a Ø25 x 25 mm solution-grown stilbene crystal in mono-energetic neutron fields in the 80-to-230 keV energy range are presented. The goal of the measurements, performed at the AMANDE facility, was to explore the capabilities of this organic scintillator to measure neutrons at the lowest possible energy with good pulse shape discrimination (PSD). The time of flight (TOF) technique was used in order to help with the neutron-gamma discrimination. The data are collected via a programmable digital acquisition (DAQ) system CAEN DT7530 using the software CoMPASS with the charge comparison method (CCM). The data are analysed using post-processing codes developed in the ROOT environment. The results show that the stilbene detector has discrimination capabilities for energies as low as 80 keV.

“…The response of the 5" sphere for 27.4 keV neutrons was derived from 24 keV and 144 keV monoenergetic neutron fields. Neutrons for 24 keV were obtained with iron filtering of a neutron beam produced by the 7 Li(p,n) 7 Be reaction, this latter reaction also being used for the 144 keV field. The neutron fields at 565 keV and 17000 keV were produced using the same reaction and nearly same field characteristics as at IRSN.…”

International key comparison of neutron fluence measurements in mono-energetic neutron fields: CCRI(III)-K10

et al. 2007

To ensure the validity of their national standards, National Metrology Institutes, NMIs, participate regularly in international comparisons. In the area of neutron metrology, Section III of the Consultative Committee for Ionizing Radiation is in charge of the organization of these comparisons. From September 2011 to October 2012, the eleventh key comparison, named CCRI(III)-K11, took place at the AMANDE facility of the LNE-IRSN, in France. Participants from nine NMIs came with their own primary reference instruments, or instruments traceable to primary standards, with the aim of determining the neutron fluence, at 1 m distance from the target in vacuum, per monitor count at four monoenergetic neutron fields: 27 keV, 565 keV, 2.5 MeV and 17 MeV. The key comparison reference values (KCRV) were evaluated as the weighted mean values of the results provided by seven participants. The uncertainties of each KCRV are between 0.9 % and 1.7 %. The degree of equivalence (DoE), defined as the deviation of the result reported by the laboratories for each energy from the corresponding KCRV, and the associated expanded uncertainty are also reported and discussed.

“…One of the main LMDN activities consists in developing and operating neutron facilities. One of them, AMANDE, is a 2 MV tandetron accelerator which produces standard mono energetic neutron fields from 2keV to 20 MeV (Gressier et al, 2004). The objective of AMANDE is to study the response of neutron dosimeters or detection systems as a function of incident energy.…”

The AMANDE facility at IRSN-Cadarache produces mono-energetic neutron fields from 2 keV to 20 MeV with metrological quality. To be considered as a standard facility, characteristics of neutron field i.e fluence distribution must be well known by a device using absolute measurements. The development of new detector systems allowing a direct measurement of neutron energy and fluence has started in 2006. Using the proton recoil telescope principle with the goal of increase the efficiency, two systems with full localization are studied. A proton recoil telescope using CMOS sensor (CMOS-RPT) is studied for measurements at high energies and the helium 4 gaseous μ-time projection chamber (µ-TPC 4 He) will be dedicated to the lowest energies. Simulations of the two systems were performed with the transport Monte Carlo code MCNPX, to choose the components and the geometry, to optimize the efficiency and detection limits of both devices or to estimate performances expected. First preliminary measurements realised in 2008 demonstrated the proof of principle of these novel detectors for neutron metrology.
