Laboratório Nacional
de Luz Síncrotron




The Brazilian Synchrotron Light Laboratory (LNLS) is part of the National Center for Research in Energy and Materials (CNPEM) with three other national laboratories. The Brazilian National Biosciences Laboratory (LNBio) conducts research in the frontier of Biosciences, focusing on biotechnology and pharmaceuticals. The Brazilian National Laboratory of Bioethanol Science and Technology (CTBE) investigates new technologies for the production of cellulosic ethanol. 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 contract with and funded mainly by the Brazilian Ministry of Science, Technology, Innovations, and Communications (MCTIC).

For more information about CNPEM, see the website.



The Direction (DIR) is a multidisciplinary group formed by the Director of LNLS, Antônio José Roque da Silva, and his staff, as well as the Innovation Management teams and Communications Department.

Antonio Jose Roque Da Silva | Director
Priscila Cassiano Alves | Management Advisor
Graziela Esteves Pereira | Administrative Assistant

The Innovation Management team is responsible for the management of innovation activities and intellectual property in strategic projects of R & D arising from internal research LNLS or demands brought by the industry. It is also responsible for coordinating the transfer of technology, licensing and R & D contracts with partner companies and development agencies.

Jose Antonio Calzavara Lemos | innovation coordinator

The Communications Department team is responsible for publicizing the activities of the Laboratory and the progress of the Sirius project. Are among the tasks the service and sending material to the press, writing texts on the research carried out, making videos and creating websites. The team supports also the organization of conferences, schools and workshops, performing pre and post release event. For more information, see the Press Room.

The Contracts and Procurement Management group is primarily responsible for meeting the administrative, legal and human resources needs specific to the project of the new synchrotron light source Sirius. The group's leader is:

Cleonice Ywamoto | Project Manager

The finance team is responsible for the budget management of the Sirius project; by national and international procurement processes; and the financial accompaniments, tax and labor project.


Amanda Caveagna Presotto | International Buyer
Gabriela Ribeiro Radomile | National Buyer
Eliel Rita Pedroso | Tax Analyst
Priscilla Moya | Financial Analyst

The project management team aims to ensure the project lifecycle - creation, conduct and completion - both to improve the current light source synchrotron UVX as development of new light source synchrotron Sirius.


Roberta Pascoal Gomes Marino | Project Manager

Marcelo Moreira Xavier | Project Coordinator

Rodrigo Spinosa | Project Coordinator

The legal team has the function to provide legal advice to procurement processes, cooperation and intellectual property agreements, obtaining licenses and signing contracts.


Renata De Vasconcellos Aquino | Lawyer

The Human Resources team is responsible, among other functions, the processes of recruitment, selection, hiring and termination of staff and fellows.


Ana Elisa Teixeira Turczyn | Human Resources Analyst


LNLS’ technical and scientific teams are gathered into the Science, Engineering and Accelerators Divisions.

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.

Harry Westfahl Junior | Leader of the Science Division

The Engineering Division is responsible for coordinating the LNLS groups in 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.

Antonio Ricardo Droher Rodrigues | Leader of the Engineering Division
Regis Terenzi Neuenschwander | Leader of the Engineering Division

The Accelerators Division is responsible for the operation of the current synchrotron light source UVX. The groups are also responsible for establishing the design specifications of components for the accelerators of the new synchrotron light source, as well as the diagnostic, acceleration and injection systems of new light source.
