We have calculated the performance of five similar target-moderator-reflector geometries that are reasonably well optimized for long-pulse source applications. For all cases, the moderators are fully coupled; that is, no poisons, decouplers, or liners are used. For each case, the energy- and time-dependent characteristics of the moderator source brightness have been parameteterized using empirical functions. These parameterizations have been made available to users of the Monte Carlo neutron scattering instrument design code MCLIB for use in evaluating the performance of neutron scattering instruments on a long-pulse source.
