Summary

The aim of the AMANDE facility of the Institute for Radiological Protection and Nuclear Safety is the production of standard mono-energetic neutron fields between 2 keV and 20 MeV using nuclear reactions between proton or deuteron beams and thin target of selected materials. The characteristics of the neutron fields are strongly dependent of several parameters of the charged particles beam energy like stability, spread and long term reproducibility as well as the current stability at the target. The neutron field reference energy is determined by the time of flight method using a pulsed beam. In that case, the pulse width and its stability are extra parameters of the beam influencing directly the neutron field characteristics. The previous parameters related to the proton beam energy have been determined through the measurements performed to establish the relation between this energy and the magnetic field in a 90° analysing magnet. The pulse width has been measured with a fast Faraday cup and the photon emission measurement at the target with a BaF2 counter and fast timing electronics. The measured performances of the AMANDE charged particles beam offer the possibility to generate neutron fields with only minor uncertainties issued from the accelerator beam energy. In addition, the sub-nanosecond pulse width allows high resolution time of flight measurements.
