TART. Coupled Neutron & Photon MC Transport
- Lawrence Livermore National Lab., CA (United States)
TART is a three-dimensional, data-dependent Monte Carlo transport program. The program calculates the transport of neutrons, photons, and neutron-induced photons through zones described by algebraic functions. The zones and elements to be included are user-specified. Any one of 21 different output tallys (methods of calculating particle transport) may be selected for each zone. A spectral reflection tally, which calculates reflections from planes and quadratic surfaces, saves considerable time and effort for some classes of problems. The neutron and photon energy deposition output tally is included in all TART calculations. The neutron and gamma-ray production cross sections are specified from 10E-9 MeV to 20 MeV. The gamma-ray interaction cross sections are specified from 10E-4 MeV to 30 MeV. The three cross section libraries are provided in binary form. Variance reduction methods included are splitting and Russian roulette at zone boundaries. Each zone in the problem can be assigned a weight.
