About LNLS


The Brazilian Synchrotron Light Laboratory (LNLS) is responsible for the operation of the only synchrotron light source in Latin America.

With open facilities, LNLS receives academic and industrial researchers from several countries. Its idealization as National Laboratory represents a mark in the institutional design of scientific research in Brazil, which enabled the construction and the implementation of an open use research facility.

Brazil has access to an extremely sophisticated infrastructure, which can be used simultaneously by many research groups. Among its advantages is the efficiency in the use of its facilities since the laboratory operates 24h a day.

Furthermore, LNLS has its own team of qualified professionals, capable of providing technical support, in order for researchers from every area to have the access to this tool on their investigations, even having no previous knowledge in the use of synchrotron light sources. Its mode of operation also allows the maintenance of an inter- and multidisciplinary environment, which enriches the learning of young researchers.

With a challenging engineering project, the Laboratory was designed to attract researchers and engineers, whose capability provided the development of important technological fields for the country. The Laboratory also developed locally the knowledge about accelerator and beamline construction, with the production of components and equipment made in Brazil as much as possible. This strategy reduced the cost of the construction of its first synchrotron light source, and allowed the mastery of knowledge related to the maintenance and improvement of the machine and of the scientific instrumentation related to it.

As a result, Brazil was the first country in Southern Hemisphere to gather the technical competence to develop and operate a great scientific equipment such as the synchrotron light source.

UVX Synchrotron Light Source



The second-generation synchrotron light source, named UVX, was designed and built by Brazilians with national technology, during the 80s and the 90s, and open in 1997. The UVX synchrotron has today 17 experimental stations, known as beamlines, which allow the execution of experiments in several techniques of microscopic analysis of materials with Infrared and UV radiation and X-rays.

Every year, the LNLS facilities benefit around 1200 Brazilian and foreign researchers, committed to over 400 studies that result in approximately 200 papers published in scientific journals. The Laboratory also foster partnerships with the Brazilian industry in research, development and innovation in energy, chemicals, pharmaceuticals and other products.



Sirius Synchrotron Light Source



The LNLS is currently building Sirius, a fourth-generation synchrotron light source, planned to be one of the most advanced in the world. Sirius will be the biggest and the most complex scientific infrastructure ever built in the Country, planned to put Brazil at a worldwide leadership position in synchrotron light generation.

The new synchrotron light source is designed to be the brightest among all the equipment in its energy class and to receive up to 40 beamlines. Sirius will open new research perspectives in many areas such as material science, nanotechnology, biotechnology and environmental sciences.



Mission and Vision

LNLS Mission: Acting as an open, multi-user and multidisciplinary National Laboratory, and providing an infrastructure in the state of the art for research, development and innovation using the synchrotron light for the academic and business communities.

LNLS Vision: Being recognized as a laboratory that welcomes scientific and technological proposals with security, efficiency and quality related to the use of synchrotron light as much as for the development of new technologies.

The Brazilian Synchrotron Light Laboratory (LNLS) is part of the Brazilian Center for Research in Energy and Materials (CNPEM) with three other national laboratories. The Brazilian Biosciences National Laboratory (LNBio) conducts research in the frontier of Biosciences, focusing on biotechnology and pharmaceuticals. The Brazilian Biorenewables National Laboratory (LNBR) is focused on biotechnological solutions for the sustainable development of advanced biofuels, biochemicals and biomaterials, using biomass and the Brazilian biodiversity. Finally, the Brazilian National Nanotechnology Laboratory (LNNano) conducts research on advanced materials, with great economic potential for the country.

CNPEM is a non-profit private research and development institution (R&D) under supervision of the Brazilian Ministry of Science, Technology, Innovations, and Communications (MCTIC).

International Scientific Committee

Every two years, the International Scientific Committee, composed of experts from large synchrotron laboratories and researchers of related areas, meets to review the operation of the synchrotron light source from the Brazilian Synchrotron Light Laboratory (LNLS). The Committee is also responsible for evaluating the infrastructure improvement projects, as well as research and development projects carried out by laboratory staff.

The Scientific Committee gathered in 2018 is comprised of the following members:
