Summary

 

The variation of the response of the instruments with the neutron energy has to be determined in well characterized mono-energetic neutron fields. The AMANDE facility, will deliver such neutron fields between 2 keV and 20 MeV in an experimental hall designed with metallic walls for neutron scattering minimization. The neutrons will be produced by nuclear interaction of accelerated protons or deuterons on thin targets of selected materials. The measuring devices to be characterized will be accurately placed with a fully automated detector transport system. The energy of the neutron field will be validated by time of flight experiments and a large set of standard detectors and fluence monitors will be used to determine the neutron fluence references.

The scattered neutron fluence and dose equivalent were calculated by the MCNP Monte-Carlo code at several measuring points in order to determine their contribution to the neutron field.
