Laboratório Nacional
de Luz Síncrotron


The answer to the challenges facing Brazil and the world in areas such as energy, health and the environment requires the knowledge of how things work on the scale of atoms and molecules. This is what allows the development of lighter materials, better drugs, more efficient fertilizers, more nutritious foods, cheap and renewable energy sources, or less polluting industrial processes.

Sirius, the new Brazilian synchrotron light source, is the largest and most complex research infrastructure ever built in the Brazil. This machine functions as a great microscope, which reveals the molecular, atomic and electronic structure of a wide range of materials and allowing research in practically any field, with the potential to solve the major problems of the present.

The Sirius Project

Sirius, the new Brazilian Synchrotron Light Source, will be the largest and most complex scientific infrastructure ever built in the country and one of the first fourth-generation synchrotron lightsources of the world. It is planned to put Brazil on the leading position in the production of synchrotron light and is designed to be the brightest of all the equipment in its energy class.

Electron Accelerators

To produce Synchrotron Light in a controlled manner, it is necessary to use particle accelerators, which are capable of controlling the movement of high-energy charged particles at speeds close to the speed of light. A Synchrotron Light Source consists of two main sets of particle accelerators: an Injection System and a Storage Ring.

Construction Works

One of the biggest challenges for Sirius is its dimensional, thermal, and vibrational stability. Because of that, the 68,000 square meter building that will house Sirius' electron accelerators and experimental stations will be among the most sophisticated civil works ever built in Brazil.

Project Management

Sirius must be a state-of-the-art equipment among the synchrotron light sources. Therefore, its success requires rigorous planning and monitoring of different aspects of management such as the procurement of materials and equipment, risk analysis, establishment and monitoring of schedule and budget, human resources and quality control.
