Call for Proposals for Commissioning Experiments

The Sirius project has reached another milestone in commissioning its accelerators and beamlines. Five new beamlines are entering the scientific commissioning stage, completing the number of six beamlines available for the user community. In addition to the beamlines, two support laboratories and the scientific computing center were also opened.

The list of available facilities is:

This call for proposals intends to supply beamtime for the users during the beamline commissioning period. The beamlines are at different stages of technical commissioning. They have not reached the final configuration and target parameters, meaning that not all experiments are feasible and not all environmental conditions can be applied. Indeed, our intention, during this period of scientific commissioning, is to receive proposals from expert users for experiments that allow us to test the beamline and at the same time improve the current instrumentation for different types of samples of interest to the community.

The Fast Track modality is open for submissions in a continuous flux, without any interruption. The proposers must have previous experience using a synchrotron beamline, especially with the required technique.

For detailed beamline conditions, please consult the webpage and contact the beamline managers. Users can submit proposals through the SAU Online portal.

An internal committee composed of the LNLS directorate, advised by beamline managers and scientific staff, is responsible for evaluating and prioritizing each beamline proposal.

The user team must be prepared to use the scheduled beam readily. Following the rules during the pandemics, only two researchers will be accepted during the experiments. For users outside the state of São Paulo and Latin America, it will be possible to request financial support, which will contemplate two users per proposal.
