PATCH, AN IBM 709 PROGRAM FOR CALCULATING GAMMA-RAY BUILDUP FACTORS FOR MULTI-LAYERED SHIELDS
Technical Report
·
OSTI ID:4095730
PATCH is an IBM 709 Fortran program for computing the dose, energy, and energy absorption build-up factor for multi-layered slab geometry shields. The code allows for n regions and six materials with a maximum of seven mesh points per region. The input data consist of the number of regions, the number of materials, their atomic numbers, and the gamma and energy absorption coefficients of each material. Typical running time for a one-region problem with five internal mesh points is less than 1 min. The running time for a multiregion problem is linearly proportional to the running time of a one-region problem. (auth)
