Title: Update to the Generic Shielding Criteria

Abstract

Generic shielding criteria have been employed at Fermilab to determine the shielding adequacy and to screen for areas which require more detailed analysis of beam loss events and are based on the calculations reported in technical report TM-1140. The calculations in that report were done 30 years ago using CASIM, a Monte Carlo program. CASIM uses the Hagedorn-Ranft to model inclusively hadronic interactions. It is valid in the energy range of 10 GeV to 20 TeV and has a lower momentum threshold of 300 MeV/c (47 MeV kinetic energy for nucleons). The goal of this study is to update the original soil shielding calculation with those estimated from the MARS code, which has a more robust and detailed physics model. Hadron-nuclear interactions are simulated with a combination of the modern theoretical models (CEM and LAQGSM) and up-to-date phenomenological models. All other processes of particle interactions with matter are described in MARS on the basis of the modern models and algorithms. MARS is valid for hadrons, leptons, photons and heavy ions with kinetic energy less than 100 TeV and greater than 1 keV (greater than 0.0215 eV for neutrons).
