A multipurpose neutron-gamma ray transport code using the Monte Carlo method for solving shielding problems using multigroup cross sections and the MARS, Multiple Array System, geometry package. Several types of estimators are available for the code, e.g., boundary crossing detectors and point detectors including a Klein Nishina estimator for gammas. Quantities of interest may be calculated at various detectors, energies, times and angles. Calculations may be in forward or adjoint mode. Running times are completely problem dependent.
Numerous reports exist.
