Lead enclosures have been used over the past decades for radiation protection at mid and high-energy synchrotron light-sources, requiring nearly 10% of the investment needed to set up a new beamline. Due to the increasing concern about neutron levels, in part due to the reduction of the photon radiation levels with the increased thickness of the hutch walls, the existing constructive models were revisited and a new constructive approach based on Carbon-Steel (CS) and High-Density Polyethylene (HDPE) is proposed for the SIRIUS beamlines, leading to increased overall radiation protection and potentially lower cost. This work is going to show preliminary simulation results, cost-comparison, as well as a few mechanical design details and prototyping initiatives.

Neutron scattering is a complementary technique to x-ray scattering scientifically, but while there are similari-ties, there are some unique challenges in the design, con-struction, and operations. This poster will provide a brief description of neutron scattering, describe the technical components of spallation neutron scattering instruments, and discuss the engineering challenges found in the design and construction of these instruments.
