Abstract

Synchrotron accelerators produce wide spectrum light beams (from infrared to x-rays) used for scientific experiments. These beams are emitted in multiple lines tangents to the accelerator's storage ring, the beamlines. Gamma radiation (bremsstrahlung) is also emitted with the light beams used for the experiments. Both the gamma radiation and the higher end of the synchrotron light spectrum are hazardous, therefore must be contained in order to allow safe operations for the experiments. The containment of this radiation is provided by radiation shielding shelters built on the storage ring beam exit points where the initial conditioning of the beam is performed (optical hutches), and on the subsequent beamline points where the beam is conditioned and/or used for the experiments (experimental hutches). The Sirius accelerator will have up to 40 beamlines, to be activated along the planned 20 years of operations. This project will develop the product and production process for optical and experimental hutches for synchrotron beamlines, not available in the Brazilian market, with initial application on the Laboratório Nacional de Luz Síncrotron Sirius project. A detailed civil/mechanical design documentation for the hutches of one beamline will be created, as well as documentation for the manufacturing and installation procedures. A prototype according to the LNLS specifications, including the critical elements of the hutches (guillotine, cable/tubing/air entry labyrinths, door) will be manufactured for the validation of production process and testings.
