The Brazilian Synchrotron Light Laboratory (LNLS) is responsible for operating Sirius, the largest and most complex scientific infrastructure ever built in Brazil and one of the most advanced synchrotron light sources in the world. This state-of-the-art laboratory allows the investigation of the composition and structure of matter in its most varied forms, opening new perspectives for research in areas such as materials science, nanotechnology, biotechnology, environmental sciences, and many others.

LNLS houses multi-user facilities, open to the Brazilian and international scientific community, and provides a sophisticated scientific instrument for academic and industrial research, benefiting thousands of scientists every year.

Organization Chart

The LNLS team is responsible for supporting users of the Laboratory’s open facilities, in addition to dedicating to internal research and development programs in synchrotron light applications in strategic scientific areas.

Director's Office

LNLS’ Director’s Office is responsible for coordinating a team of around 200 researchers, engineers, and technicians, responsible for operating, maintaining, and updating the beamlines of the new Brazilian synchrotron light source, Sirius, and associated instrumentation.


The LNLS team is organized into six divisions: three divisions focused on the development of beamline science; a division dedicated to all aspects of beamline design and construction; a division responsible for the acquisition and processing of beamline data; and a division connected to the operation and physics of electron accelerators.

Science Advisory Committee

The Science Advisory Committee (SAC) is composed of international experts from large synchrotron laboratories and researchers of related areas, which meets regularly to review the LNLS’ operation. The Committee is also responsible for evaluating the infrastructure improvement projects, as well as research and development projects carried out by Laboratory staff.
