Description
The KLOE Pb-scintillating fiber calorimeter, primarily designed as an
electromagnetic calorimeter, showed a superior neutron efficiency in a
measurement performed in the energy range [20,180] MeV at TSL (The
Svedberg Laboratory, Uppsala) presented in a parallel contribution to this
conference. A detailed simulation of the calorimeter - a complex geometrical
structure of 200 layers of thin (0.5 mm) grooved lead foils and 1 mm
diameter scintillating fibers glued inside - and of the main elements of the
TSL beamline has been performed with the Monte Carlo code FLUKA. The
simulated response of the calorimeter to neutrons, together with the
experimental validation by the TSL data, is presented, showing a high
neutron efficiency, which ranges between 40% and 50%. The reasons of a
such enhancement of the efficiency, in comparison with the typical neutron
counters, are investigated and discussed, opening to the possibility of a new,
innovative neutron detector.
