Monte Carlo and analytical calculations for investigation of radiation streaming and labyrinth design for the Iranian Light Source Facility

This study investigates two proposed labyrinth layouts for Iranian Light Source Facility from shielding viewpoint: three and five-legged labyrinths. The attenuation of photons and neutrons along the labyrinth is studied by using FLUKA Monte Carlo code and compared with the most common analytical formulas and reliability of each method is judged. Finally, the labyrinth layout that meets our shielding design goal, is introduced.
