Neutron production by hadron-induced spallation reactions in thin and thick Pb and U targets from 1 to 5 GeV

Abstract The reliability and relevance of experimental data and calculations for the design and construction of the target assembly of spallation neutron sources are discussed. New experimental data obtained in a new approach for neutron production in thick targets of Pb and U are presented for 2–5 GeV/c hadrons. It is found that the observed mean neutron multiplicities depend essentially on the incident available energy only while the variation with particle species for p, d, p , K, and π is within 10%.
