The open facilities of the Brazilian Synchrotron Light Laboratory (LNLS) serves Brazilian and foreign researchers who wish to use the experimental stations of the Laboratory to carry out their investigations.
Calls for the submission of Standard Research Proposals are announced twice a year, one for each semester, depending on the beamline or area of research, and made through the SAU Online system. Before submitting a proposal, It is recommended that users check for the available beamlines, services, and technologies, as well as for specific recommendations for the sample preparation, protocols, and other detailed specifications about the research proposal submission process. Other types of proposal submission are also available and can be checked below under “Proposal Types”.
Beamlines: Find the available beamlines.
Support Facilities: Find the available support facilities. It is possible to submit a proposal for using the support facilities, or they may be indicated in the beamline submission if necessary.
Once the proposal is scheduled, the Local Contact is the reference person at LNLS designated to interact with Users throughout the preparation and execution of the experiments. The interaction between Users and Local Contact may be of two kinds:

Calls for proposal submission are announced through this website and mailing list of registered users in the SAU Online system. Users and researchers can also recieve our communications by entering their e-mail in the form below. Announcements include the opening of proposal submissions and registration for events.
There are four possible types of research proposal submission: Standard Research Proposal (STD), Fast Track Access (FTA), Long Term Proposal (LTP) and Industry Rapid Access (IRA).
This is the standard procedure to get access to the LNLS beamlines and support labs. The users ask for beamtime for a specific experiment on a given beamline. The proposals follow the normal review process and the beamtime may be split into more than one round. After each experimental round, the Users’ team provides an experimental report and other feedback.
Published results must acknowledge the beamline/facility, National Laboratory and CNPEM. A copy of each paper or thesis should be transmitted to LNLS management and a copy of each paper or thesis should be transmitted to LNLS management and CNPEM’s library.
Users from Brazil and Latin America receive grants to perform the experiments.
This type of proposals intends to improve the access to LNLS beamlines for experiments that demand little preparation and involve simple sample and safety concerns on standard beamline setups. It is intended for users that have already experience on the required technique. The team – or main proposer – must have already submitted and get approved proposals at the LNLS beamlines. It can be used to complete and/or complement experimental results to conclude scientific publications and/or thesis works.
Specific Rules:
The LNLS management will decide the amount of beamtime allocated to FTA for each beamline:
This submission type aims at establishing a long-term commitment by LNLS to provide beamtime in one or more beamlines for a two-year period. The main criterion is the scientific excellence of the project. However, some additional criteria must be considered:
Specific Rules:
Like the FTA application, IRA is designed to improve the access to LNLS beamlines for experiments that demand little preparation and involve simple sample and safety concerns on standard beamline setups. Industrial users must have already some experiences on the required technique. Funding is not provided, and costs should be discussed depending on the need for assistance of a LNLS specialist during the experiments and on data handling.
Specific rules:
LNLS management will decide the amount of beamtime allocated to IRA for each beamline:
To start the proposal submission process, the user must be registered on the SAU Online portal. To create a new account on the portal, the user must click on “Create a new SAU Online Account”. On their first access, the user must provide personal and professional information. Registration is required only for the first access and may be completed regardless of the proposal submission period. The information provided may be updated at any time.
Once registered on the SAU Online portal, the user must click on “Submit a new Proposal” and follow the instructions to complete the Research Proposal Form.
All proposals must be written in English.
UPDATE TO THE LNLS/Sirius PROPOSAL SUBMISSION FORMAT
In order to improve the scientific evaluation process and optimize the use of LNLS/Sirius beamlines, the format for submitting proposals in the regular call has been updated.
In previous calls, an increase in excessively long and generic texts was observed, in some cases possibly generated with the aid of language models (LLMs), which made it difficult to clearly identify the central idea of the proposal and the intellectual authorship of the researchers. In addition, lengthy texts make the evaluation process more laborious without necessarily contributing to better scientific analysis.
The new format seeks to prioritize clarity, objectivity, and adherence to the scientific method, allowing direct identification of: (i) the scientific hypotheses to be tested; (ii) whether the proposed experiment is suitable to test them; and (iii) the level of maturity of the study, based on prior characterizations already carried out.
A clearer detailing of these prior characterizations and how they support the proposed experiment is now also required, which is essential to assess the feasibility and stage of development of the research.
Finally, the changes align proposal submission with the new Experimental Validation Levels (EVLs) and Technical Validation Levels (TVLs) model currently used to classify the degree of scientific and technical maturity of experiments at the beamlines. (Information can be checked at this link)
These updates aim to make evaluation more efficient, transparent, and consistent, benefiting both proposers and the Sirius user community.
The Research Proposal Form is the main document that describes the motivation, objectives, samples and prior characterizations, and experimental methods. Below are instructions for completing the Research Proposal Form.
It must follow the following structure:
Main observation + system/material studied + main technique
This structure reflects how science at synchrotron light sources is organized, explicitly stating:
The title is not intended for outreach and is mainly used for indexing, organization, and classification of proposals in the system.
It is important to highlight that:
Prior characterization and how these results support the proposed experiment. The text referring to graphical experimental evidence must be placed in this field.
Graphical experimental evidence: Upload a file with a maximum of five pages, figures only, numbered, without captions. The explanatory text for the figures must appear in the previous field “SAMPLES AND PRIOR CHARACTERIZATION”.
Select an EXPERIMENT (EVLs):
For each experiment provide:
The Sample and Safety Form is the document that describes the samples and related storage and safety concerns. It is completed online in the SAU Online portal.
