Abstract:
At the ENEA TRIGA research reactor (Casaccia Research Center, Rome), a new neutron collimator
has been designed and installed at the neutron tangential channel. This collimator, that is part of a neutron/X-ray
facility for NDT analysis, was experimentally characterized and optimized in terms of thermal neutron flux, its
spatial/energetic distribution, photon air KERMA and effective beam diameter. This paper shows the
methodologies and the results of the experimental analysis that was carried out.
