Registrations are open for the ER2LS 2020

The Escola Ricardo Rodrigues de Luz Síncrotron will happen between 13 and 24 July 2020

Registrations are open to the Escola Ricardo Rodrigues de Luz Síncrotron (ER2LS), which will take place between July 13th and 24th, 2020 on the campus of the Brazilian for Research in Energy and Materials (CNPEM), in Campinas, SP. The ER2LS seeks to expand the capacity of the current LNLS user community, as well as promote the formation and training of new users, which have the potential to use synchrotron light techniques in their research areas.. The Escola Ricardo Rodrigues de Luz Síncrotron (ER2LS) is a new designation for the Brazilian Synchrotron School (EBS) and pays tribute to Prof. Ricardo Rodrigues, pioneer of synchrotron light in Brazil.

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.

Sirius’ booster reaches extraction energy

The new Brazilian fourth generation synchrotron light source will be open for researchers next year

On October 16th, another important stage was achieved in the installation of the largest and most complex project in Brazilian science. Electrons in Sirius’ booster reached the extraction energy of 3 GeV (Giga-electronvolts). Upon reaching this energy in the Booster, electrons are transferred to the main accelerator, called the storage ring. This accelerator is currently assembled, and the next challenge is to get electrons to make a complete loop around it.

Registrations are open for the Carnaúba Workshop

The first CARNAÚBA Workshop ‘’Sirius Workshop on X-ray Nanospectroscopy, Nanodiffraction and Nanoimaging’’ will be held on October 8th and 9th, 2019.

The first CARNAÚBA Workshop will bring together the LNLS community – external users, staff scientists and engineers – and experts working in the field of X-ray spectroscopy, diffraction and imaging at leading facilities around the world to present and discuss the new scientific opportunities offered by X-ray nanoprobes with scanning energy capabilities.

CNPEM welcomes 16 thousand visitors in its Open Day

The event registered a record of public, gathering around 16 thousand people in the campus

On June 29, 2019, the Brazilian Center for Research in Energy and Materials (CNPEM) held the fourth edition of its open day called "Ciência Aberta" (Open Science). Students, families and children of all ages participated in guided visits through the National Laboratories, hands-on activities, informal lectures by researchers, among other attractions.

This year, the new Brazilian synchrotron light source, Sirius, was open for public visitation, which included booths and exhibitions covering several aspects of such complex machine, from design to scientific applications.
