MANACÁ beamline receives new round of experiments

LNLS opens a call for proposals in other research areas for macromolecular crystallography experiments

In the last few months, the first experiments on the MANACÁ beamline were carried out by external researchers dedicated to studying the molecular mechanisms related to the action of the SARS-CoV-2 virus.

Now, continuing the scientific commissioning phase of this beamline, researchers from other fields are invited to submit their proposals to use the MANACÁ beamline.

Dedicated to macromolecule crystallography, MANACÁ allows the study of the three-dimensional structure of human proteins and enzymes and pathogens, with atomic resolution.

Sirius receives the first experiment from external users

Little-understood protein from the SARS-Cov-2 virus is one of the targets of the study by researchers from USP at the synchrotron light source

In response to the pandemic, the Brazilian Center for Research in Energy and Materials (CNPEM), a private non-profit organization under the supervision of the Brazilian Ministry of Science, Technology, and Innovations (MCTI), anticipated the opening of Sirius' first beamline to support research related to Covid-19. Researchers from the University of São Paulo (USP) were the first users of the largest and most complex scientific infrastructure in Brazil.

First experiments are carried out on Sirius

Crystals of SARS-CoV-2 proteins were the first samples analyzed

The new Brazilian synchrotron light source, Sirius, from the Brazilian Synchrotron Light Laboratory (LNLS) at the Brazilian Center for Research in Energy and Materials (CNPEM), carried out the first experiments on one of its beamlines this week. The first research station to start operating, still in the commissioning stage, can reveal details of the structure of biological molecules, such as viral proteins. These first experiments are part of an effort by CNPEM to provide a cutting-edge tool to the Brazilian scientific community working in SARS-CoV-2 research.

In these initial analyses, CNPEM researchers observed crystals of a coronavirus protein, essential for the development of COVID-19. The first results reveal details of the structure of this protein, important for understanding the biology of the virus and supporting research that seeks new drugs against the disease.

Call for proposals on an exceptional basis

Exceptionally, LNLS opens a call for proposals for crystallography users who wish to analyze samples related to COVID-19

We are pleased to inform that Sirius has reached another milestone in its commissioning. In the last few days, the first experiments were carried out on the MANACÁ beamline. The initial tests reproduced structural data already reported in the literature, including the 3CL protein from SARS-CoV-2, indicating that the beamline, still in the scientific commissioning phase, is already able to generate reliable data.

In view of this milestone and considering the public health crisis caused by the COVID-19 pandemic, we invite, on an exceptional basis, researchers who have previous experience with the protein crystallography technique and samples related to the disease to submit their proposals to use the MANACÁ beamline.

LNLS has a new Director

Harry Westfahl Junior has served as LNLS’ scientific director since 2013, and coordinates Sirius’ beamline design and construction

The new director of the Brazilian Synchrotron Light Laboratory (LNLS), Harry Westfahl Junior, took office on January 13th, at a ceremony held at the Brazilian Center for Research in Energy and Materials (CNPEM). Westfahl has worked in CNPEM since 2001, and, for the last seven years, held the position of LNLS Scientific Director. Westfahl succeeds French physicist Yves Petroff, one of the world's leading synchrotron light experts.

During the inauguration ceremony, CNPEM Director-General Antonio José Roque da Silva highlighted the competence of the new director: “At this key moment for the institution, in which we will have to structure the start of operations at Sirius, Harry's experience, competence, and multidisciplinary background will be a key factor. ”

Obituary: Antonio Ricardo Droher Rodrigues (1951 – 2020)

Ricardo Rodrigues could unite enthusiasm, creativity, technical and scientific knowledge

The engineer and physicist Ricardo Rodrigues (Antonio Ricardo Droher Rodrigues), leader of the engineering team which developed Sirius, has died on January, 3rd, 2020. Sirius is the second synchrotron light source in Brazil, and it is currently being commissioned at the Brazilian Center for Research in Energy and Materials (CNPEM).

Born in Curitiba, Brazil, on November, 10th, 1951, Ricardo was the technical leader of the pioneer project which gave Brazil the first synchrotron light source in the Southern Hemisphere. UVX was developed and built from 1987 to 1997 in the Brazilian Synchrotron Light Laboratory (LNLS), one of CNPEM's National Laboratories.

First x-ray microtomography images obtained at Sirius

Two days after storing electrons in Sirius’ storage ring, the team have performed the first x-ray microtomography analysis at the new source

Two days after storing electrons in Sirius’ storage ring, the CNPEM´s team have performed the first x-ray microtomography analysis at the new Brazilian synchrotron light source. Through a simple proof of concept experiment, using less than ten thousandth of the expected power, it was possible to observe the arrival of synchrotron light for the first time in one of Sirius' future experimental stations. This is a major milestone for the project, and a victory for Brazil's science and technology.

Sirius reaches his first stored electron beam

The new Brazilian synchrotron light source continues its successful commissioning

Last Saturday, December 14th, CNPEM’s team stored electrons in Sirius's storage ring for several hours. This is a prerequisite for producing synchrotron light, and it happens only a few weeks after the first electron loop around the main accelerator was achieved.

In addition, on Monday, December 16th, with the connection of the accelerator to one of the beamlines set up for testing, it was possible to receive the first X-ray pulse, still discrete due to the small number of circulating electrons.

First electron loop around Sirius’ Storage Ring

This is one of the most important stages of the largest scientific project in Brazil

The Sirius project has just completed one of its most important steps: the first electron loop around its main particle accelerator, called the Storage Ring. In this large structure, 518 meters in circumference, the electrons accelerated to very high energies produce synchrotron light: a very bright light used in scientific experiments that could revolutionize knowledge in health, energy, materials and more.

The first loop, achieved on November 22nd, demonstrates that thousands of components such as magnets, ultra-high-vacuum chambers and sensors are working in sync, and that the entire structure, with parts weighing hundreds of kilograms, have been aligned to micrometer standards (up to five times smaller than a strand of hair) needed to guide the trajectory of the particles.
