In this paper, we investigate the possibility of using the CEA Cadarache MASURCA experimental reactor to deliver a well-characterized, fairly-intense beam of intermediate-to-fast energy neutrons. We report the results of numerical simulations which have been performed to establish the feasibility of such a beam. We show that it is possible to achieve a beam in- tensity of more than 108 neutrons cm-2 s-1 in the experimental room past the reactor biological shield, ~80% of the neutrons having energies above 100 keV, and 96% above 10 keV. The characteristics of this MASURCA extracted beam are compared with those of other neutron physics facilities designed to produce continuous beams of fast neutrons. The analysis shows that the MASURCA setup would have several distinctive advantages.

Abstract
In this paper, we investigate the possibility of using the CEA Cadarache MASURCA experimental reactor to deliver a well-characterized, fairly-intense beam of intermediate-to-fast energy neutrons. We report the results of numerical simulations which have been performed to establish the feasibility of such a beam. We show that it is possible to achieve a beam in- tensity of more than 108 neutrons cm-2 s-1 in the experimental room past the reactor biological shield, ~80% of the neutrons having energies above 100 keV, and 96% above 10 keV. The characteristics of this MASURCA extracted beam are compared with those of other neutron physics facilities designed to produce continuous beams of fast neutrons. The analysis shows that the MASURCA setup would have several distinctive advantages.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
