Comparison of MAVRIC/Monaco and TRIPOLI-4 Simulations of the LLNL Pulsed Spheres Benchmark Experiments

* Corresponding author
Abstract : Oak Ridge National Laboratory and the Commissariat à l’Énergie Atomique et aux Énergies Alternatives – Centre de Saclay performed simulations of the Lawrence Livermore Pulses Spheres (LPS) benchmark experiments to add these results to the suite of validation problems of MAVRIC/Monaco and TRIPOLI-4$^®$. By the middle of 1971, the LPS experiments measured the neutron emission spectra for 17 isotopic, elemental, and compound spherical targets via time-of-flight techniques. These spherical targets varied in thickness from 0.5 to 5 mean free paths for 14-MeV neutrons. The source in each measurement was 14-MeV neutrons born from deuterium-tritium fusion reactions at the center of each sphere. These neutrons were born at times that resulted in a Gaussian distribution with a mean and full-width-at-half-maximum of 0 and 4 ns, respectively. The time-of-flight measurements were made along two different flight paths, 30° (Pilot B plastic or NE213 liquid scintillator) and 120° (NE213). These angles were measured with respect to the direction of travel of the deuterons.
