Book Description
MACE is a Monte Carlo code, written for the IBM 7090, to evaluate the efficiency of radiation collimators in terms of the ratio of collided to uncollided flux reaching a target. The analysis can be performed with as many as 30 energy groups. Up to 5 materials (8 elements) may be used in the description of the collimator system. Provisions are included for specification of source particle density and angular distribution functions and for tilt of the source plane with respect to the axis of the collimator. (auth).

Book Description
A Monte Carlo study has been made to investigate the fast-neutron spectrum and angular distribution in a large assembly of paraffin wax. The shield configuration and detector locations were chosen so that techniques currently used in calculations and experiments of neutron deep penetration could be evaluated. A modified version of the Flexible Monte Carlo (FMC) procedure, along with several data-preparation and analysis routines, was developed and used to analyze the results. Calculations were performed to determine the angular-flux values at penetration thicknesses ranging from 5 cm to 60 cm. A comparison of the calculated and measured angular flux data was made for several penetration thicknesses and angles of incidence for which experimental data were taken. A divergence in spectral shapes at 0 degree is attributed to a streaming effect in the experimental data for direct-beam flux. Except for this difference, the Monte Carlo results are in good agreement with a large range of comparable experimental results. (Author).
