Abstract

This document was prepared in the framework of PDS-XADS (Preliminary Design Studies of an eXperimental Accelerator Driven System) as a contribution to Deliverable 60.1, Work Package 4.3, which analyses the characteristics of different target options. Here some features of the windowless Lead-Bismuth target (coupled with a Lead-Bismuth cooled core) are investigated by means of the Monte Carlo computer code MCNPX: the neutron yield (14.5 neutrons/proton), the formation of the spallation products, the heat deposition (at BOL l.3MW are deposited in the whole target coolant), the different contributions to the neutron flux (the maximum value at BOL is 3.7E15 n cm-2 sec-1 and in the central zone of the target the contribution from the core varies radially from 23% to 90%) and the proton flux (which decreases linearly as the protons penetrate into the target).
