A new neutron spectrometer, designed to simultaneously respond from the thermal domain up to hundreds of MeV neutrons, was designed and built in the framework of the INFN project NESCOFI@BTF. It has been called SP 2 (SPherical SPectrometer) and it consists of 31 thermal neutron detectors embedded in a 25cm diameter polyethylene sphere with an internal 1cm thick lead shell. The new spectrometer...
This communication describes the design specifications for a neutron spectrometer consisting of 31 thermal neutron detectors, namely Dysprosium activation foils, embedded in a 25cm diameter polyethylene sphere which includes a 1cm thick lead shell insert that degrades the energy of neutrons through (n,xn) reactions, thus allowing to extension of the energy range of the response up to hundreds of MeV...
