abstract = "The first round of the optimization of the target/moderators/reflector assembly for the Spallation Neutron Source Second Target Station at the Oak Ridge National Laboratory was completed with the goal to achieve cold neutron pulses with outstanding brightness. The simulations were performed with the MCNPX particle transport code within a global optimization procedure. Based on the projected STS neutron scattering instruments preferential treatment was given to the coupled moderators. Mostly due to explicit optimization for the peak brightness, and the resulting compact target and moderator design, promising results were obtained. For the STS operating at 467 kW beam power at 10 Hz, projected gains in the peak brightness are 10 to 13 times for the coupled para-H2 moderators, 3 times for decoupled para-H2 moderator and 4 times for the decoupled H2O moderator with respect to the First Target Station operating at 2 MW beam power and 50 Hz pulse repetition rate.",
