Evaluation of Radiation Skyshine From the Main Rings of the Dafne Project

Key Points

This research aims to assess the skyshine effect on radiation doses around the Main Rings of the DAPHNE Project.
Evaluated dose equivalents based on distance from the machine building and altitude.
Used the FLUKA code for source definition.
Simulated radiation transport with the CERN version of the MORSE code.
Calculated radiation contributions from both neutron and photon emissions.
Suggested a roof design without local shields for certain machine sections.
Recommended the removal of existing windows in the machine housing to enhance safety.

Abstract

To properly design the roof shielding for the Main Rings of the DAPHNE Project, the dose equivalents due to the skyshine effect as a function of distance from the machine building and of the altitude have been evaluated. The calculations, for both neutron and photons, were performed in two steps: source definition and radiation transport. For the first step the code used was FLUKA. The transport of the emitted particles was simulated using the CERN version of the MORSE code. From the results obtained two alternatives are suggested: - a roof covering the sections of the machine without local shields; - the removal of the windows existing in the building housing the machine.
