Laboratório Nacional
de Luz Síncrotron


Inauguration and Consolidation


The first Synchrotron Light Source from Brazil and from the Southern Hemisphere begins to be designed in 1987 and is inaugurated 10 years later, in 1997. Learn more about the history of the Brazilian Synchrotron Light Laboratory from 1997 to 2008.






On July 1st, the LNLS Synchrotron Light Source, called UVX, is finally open to the science and technology communities.



On July 1st, the LNLS Synchrotron Light Source, called UVX, is finally open to the science and technology communities. At the time, the source had seven beamlines: X-ray absorption spectroscopy(XAS), soft X-rayspectroscopy (SXS), small angle X-ray scattering (SAXS), X-ray diffraction (XRD), protein crystallography (PCR) and two beamlines in the ultraviolet spectroscopy, one with a spheric grating monochromator (SGM) and the other with a toroidal grating monochromator (TGM).

In November, the eighth annual users meeting is held at the Laboratory, the first after the start of operations, which already had scientific papers that included experimental results obtained at the LNLS.


The Laboratory ceases to exist as a CNPq institute and becomes the first Brazilian scientific institution to be managed by a Social Organization, with the creation of the Brazilian Association of Synchrotron Light Technology – ABTLuS. The association is responsible for managing the Brazilian Synchrotron Light Laboratory, in the form of Management Contract signed with CNPq and Ministry of Science and Technology (MCT) on January 29.


Meeting the demand of users, the instrumentation beamline is adapted into a new X-ray diffraction beamline (XRD2), and a beamline dedicated to X-ray and UV Lithography (XRL) is built, totaling 10 beamlines. In this same year, the Electron Microscopy Laboratory (LME)is inaugurated and open to users.


The commissioning of the new 500 MeV Booster is concluded, allowing the regular operation with an injection current of 200 mA in the storage ring, thereby increasing the photon flux produced by synchrotron light source. The start of operations of the new Booster within only 3 years after the start of the project and at a considerably lower cost than on the international market have shown the consolidation of the technical competencies in accelerator engineering available at the LNLS.


The RF systems for the UVX storage ring was updated to accommodate the future installation of insertion devices: equipment capable of producing a much larger flux of synchrotron light than the bending dipoles.


In 2003 and 2004, the Ombudsman of the LNLS, Gerardo Gerson Bezerra de Souza, a researcher at the Chemistry Institute of the Federal University of Rio de Janeiro, at the end of the 13th and 14th RAU, emphasized the need to initiate the studies on a new Synchrotron Light Source for LNLS.


The first insertion device of the UVX storage ring is installed, a 2 Tesla hybrid multipolar Wiggler.


The implementation of the new shielding and radiological protection system of Synchrotron Light Source is finished, improving the working conditions of users of synchrotron light source allowing the permanence of users in the experimental hall even during electron injection periods.


The second UVX insertion device is installed, an Elliptical PolarizationUndulator (EPU) type Apple II.


In 2008, there is also the start of preliminary studies for the construction of a new low-emittance storage ring for LNLS, provisionally called LNLS-2. A report is sent to the Ministry of Science and Technology and, with the approval and allocation of the first financial resources, the studies continue.
