The Brazilian Synchrotron Light Laboratory (LNLS) is responsible for operating the only synchrotron light source in Latin America. With open facilities, LNLS offers an extremely sophisticated infrastructure for academic and industrial researchers, both Brazilian and foreign.


The Science Division has the dual mission of providing users with a research infrastructure with the best possible performance and of developing internal scientific research exploring the limits of the available instruments. The division also manages the beamlines of the current synchrotron light source UVX and to develop new scientific fields and techniques through the development of beamlines for the new synchrotron light source Sirius.

    Engineering and Accelerator Divisions

    The Engineering and Accelerator Divisions are responsible for activities related to the construction of the new light source synchrotron Sirius, including civil works, infrastructure and accelerator components, with specifications defined in conjunction with the Science Division, as well as for the operation of the current synchrotron light source UVX.


      The first synchrotron light source of Brazil and of the Southern Hemisphere begins to be designed in 1987 and is inaugurated 10 years later, in 1997. Learn more about the history of the LNLS.


      The Synchrotron Light Source is a machine designed to produce synchrotron light for unveiling the structure of materials to understand its fundamental properties. Learn more about synchrotron light sources.


      With open facilities, the Brazilian Synchrotron Light Laboratory (LNLS) offers an extremely sophisticated infrastructure for academic and industrial researchers, both Brazilian and foreign, that can be used simultaneously by several research groups and operates 24 hours a day.


      In addition to providing for users, the LNLS internal team is also dedicated to the internal research program in applications of synchrotron radiation in scientific areas that are strategic for Brazil. In addition, the laboratory is also dedicated to development programs aimed at the construction of beamlines and instrumentation to the new synchrotron light source Sirius.


      The LNLS also seeks to promote innovation in the country through interaction with the Agriculture Industry and Services sectors. This is done through partnerships in research, development and innovation, technology transfer and by providing of technological services.


      Finally, the Laboratory organizes and promotes events such as training courses, schools, seminars, workshops and other educational activities for the training of skilled personnel in the subjects of unique competence of the laboratory.

      UVX Synchrotron Light Source

      UVX’s experimental stations, called beamlines, allowed the execution of several experiments in microscopic analysis techniques using infrared, ultraviolet radiation and X-rays.

      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.
