“…The work reported in (10) demonstrated that a stilbene detector could be used as a 'low resolution' photon spectrometer using simulated gamma response functions. Here, we report similar work, adapted to the [100 keV-1.5 MeV] neutron measurement range.…”

The time-of-flight (ToF) method with scintillators is routinely used for determining neutron energy. However, a technical difficulty related to the loss of scintillator efficiency below 1 MeV makes this technique difficult to implement for the energy decade [100 keV–1 MeV]. New crystal production techniques provide stilbene scintillators efficient in this low neutron energy region, making it possible to extend the ToF technique below 1 MeV. In this manner, measurements of secondary reactions (d,n) on carbon or oxygen nuclei in this range become feasible, which should lead to improved reference calibration conditions in neutron fields produced by a deuterium ion beam.

Stilbene scintillators have now the capability to extend the neutron energy measurement from 100 keV to 1 MeV. To be used as spectrometers, scintillators have to be characterized in entire energy range covered. For the photon characterization, usual calibration source determined the calibration and the resolution function. To do the photon matrix, MCNP PTRAC simulations were done between 59 keV up to 7 MeV. Using MCNP PTRAC allows the calculation of the photon response matrix from the tracking detail of the electron energy deposition in the crystal, including the effect of the Aluminum protection around. Resolution and sensibility obtained from gamma sources are applied later to the calculated photon matrix. For neutron characterization, Time-Of-Flight measurements on white neutron spectra were realized. However, the fluence reference on these spectra begins at 1 MeV. So, the shape of the response function was measured using stilbene scintillators on 100 keV1 MeV decade. After, the monoenergetic neutron reference of AMANDE facility was used to give neutron fluence normalization below 1 MeV. This method could characterize these scintillators for neutron energy from 100 keV up to 22 MeV.
