MASH, the Monte Carlo adjoint shielding code

Conference ·
OSTI ID:6311686

The Monte Carlo Adjoint Shielding code (MASH) calculates protection factors for armored military vehicles by coupling a forward discrete ordinates calculation with an adjoint Monte Carlo calculation. The discrete ordinates calculation determines the fluence on a coupling surface surrounding the vehicle due to an external neutron/photon source. The Monte Carlo calculation determines the effectiveness of the fluence at that surface in causing a response in a detector within the vehicle, i.e., the ''dose importance'' of the surface fluence. A coupling code folds the fluence together with the dose importance, giving the desired dose response. This coupling code can also rotate the vehicle, move it to different distances from the source, and perturb the energy response of the detector. 10 refs., 4 figs., 2 tabs.
