Monte Carlo analysis of accelerator-driven systems: Studies on spallation neutron yield and energy gain
-
S. R. Hashemi-Nezhad
Abstract
The neutron yield in the interaction of protons with lead and uranium targets has been studied using the LAHET code system. The dependence of the neutron multiplicity on target dimensions and proton energy has been calculated and the dependence of the energy amplification on the proton energy has been investigated in an accelerator-driven system of a given effective multiplication coefficient. Some of the results are compared with experimental findings and with similar calculations by the DCM/CEM code of Dubna and the FLUKA code system used in CERN.
Abstract
Die Neutronenausbeuten in der Wechselwirkung von Protonen mit Blei- und Uran-Targets wurden mit dem LAHET Code untersucht. Dabei wurde die Abhängigkeit der Neutronenmultiplizität von der Target-Geometrie sowie der Protonenenergie theoretisch berechnet und die Abhängigkeit der Energieverstärkung von der Protonenenergie und der vorgegebenen effektiven Neutronenmultiplikation untersucht. Einige Resultate werden mit den experimentellen Ergebnissen, sowie mit analogen theoretischen Modellen, wie dem DCM/CEM Code aus Dubna und dem FLUKA Code aus CERN, verglichen.
