Sirius announces results for third round of research proposals

232 new projects will be carried out at the Sirius beamlines during the first half of 2024

The Brazilian Center for Research in Energy and Materials (CNPEM), an organization overseen by the Ministry of Science, Technology and Innovation (MCTI), has released the list of scientific projects selected to be conducted within the research facilities at Sirius, Brazil's largest and most complex research infrastructure dedicated to analyzing the structure of all types of matter at the micro and nano scales.

Delta undulator installed on the Sabiá beamline

Component is the first of its type to be installed in the storage ring of a synchrotron light source

This November, group members in the Technology Division at CNPEM were involved in the process of replacing the undulator on the Sabiá beamline, which operates in the soft X-ray range and is dedicated to X-ray absorption techniques, particularly linear or circular dichroism of magnetic materials (XLD, XMLD, XMCD) and photoemission electron microscopy (PEEM).

CNPEM opens third official call for research projects at Sirius

Alongside the 6 research stations already operating, 4 new beamlines will begin to receive regular proposals during this call

Sirius, the new Brazilian synchrotron light source planned and operated by the Brazilian Center for Research in Energy and Materials (CNPEM), an organization supervised by the Ministry of Science, Technology and Innovation (MCTI), has opened its third regular call for proposals for research to be conducted in its first ten experimental stations.

Manacá beamline at Sirius expands to allow investigation of “small molecules”

A joint effort, involving local and external researchers, validated crystallographic study of small molecules, alongside the usual with proteins

Manacá, one of the beamlines operating at Sirius, was designed for analysis of the three-dimensional structure of macromolecules, especially proteins. However, in late May, a group of specialists, including physicists and chemists from universities in Brazil and abroad, came to Sirius to validate the current instrumentation in the beamline, so that it would be possible to welcome the research community that studies what are known as small molecules.

Sirius announces selected applicants in its second call for research proposals

100 new projects will be carried out in the six research stations already open to users in Brazil’s largest scientific infrastructure

The Brazilian Center for Research in Energy and Materials (CNPEM), an organization overseen by the Ministry of Science, Technology and Innovation (MCTI), has released the list of scientific projects selected to be conducted within the research facilities at Sirius, Brazil's largest and most complex research infrastructure dedicated to analyzing the structure of all types of matter at the micro and nano scales. One hundred proposals were chosen out of the 281 submitted during the second official call for research projects to be conducted at Sirius during April 3–24 of this year. The selected projects will be carried out during the second half of 2023, between August 2 and December 16.

Mogno beamline receives its first external users

First research conducted during the commissioning period of the Sirius beamline dedicated to X-ray micro and nanotomography seeks to investigate a bacterium-associated vascular disease of citrus

Mogno is the beamline at Sirius dedicated to obtaining tomographic images with resolution that varies from the micro to nanometric scales. The Mogno beamline uses high-brilliance X-rays at 22, 39, and 67 keV produced by the particle accelerators at Sirius and offers real-time and non-invasive characterization of the internal structures of materials at different spatial scales.

Primeiro feixe de luz UV gerada pelo Sirius chega à linha Cedro

Cedro research station receives its first ultraviolet beam generated by Sirius

Arrival of the UV beam is a milestone in the commissioning process

This week the Cedro experiment station received its first synchrotron light beam after being connected to the Sirius particle accelerators. This beamline dedicated to circular dichroism spectroscopy will be an important tool for studying the structure of chiral molecules such as proteins, nucleic acids, and carbohydrates. Using the ultraviolet region of the synchrotron light generated by Sirius, the beamline will offer researchers the ability to quantify the contents of the secondary structure of proteins and assess their stability and interaction with other molecules. The ultraviolet beam could be observed on Monday, May 29 after extensive efforts involving reassembly and positioning in the beamline's mirror chamber. Learn more about the Cedro beamline

Sirius begins operating in top-up mode, ensuring more stable beamlines

The new operating mode ensures more stability and more photons emitted to the beamlines

Since late March, Sirius has implemented a new operating mode that involves injecting new electrons into the storage accelerator every 3 minutes, guaranteeing that the current remains nearly constant throughout its operations. This results in around 25% more photons emitted per day compared to the previous mode, in which electrons were injected every 8 hours and beam current decayed during this period.

CNPEM opens second official call for research proposals at Sirius

In the first call for proposals, the new, more inclusive, and collaborative selection process attracted proposals from scientists in 15 countries and 17 Brazilian states, most notably the Northeast of the country.

Sirius, the Brazilian synchrotron light source planned and operated by the Brazilian Center for Research in Energy and Materials (CNPEM), an organization supervised by the Ministry of Science, Technology and Innovation (MCTI), has opened another regular call for proposals for research to be conducted in the first six operating experimental stations.

ASSEMBLY OF THE PAINEIRA BEAMLINE

The beamline is dedicated to X-ray diffraction of polycrystalline materials and will operate in the energy range of 5 to 30 keV

PAINEIRA is one of the beamlines of the Sirius synchrotron light source, at 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).

The PAINEIRA beamline will be dedicated to X-ray diffraction experiments of polycrystalline materials (PXRD). It will combine the benefits of high brightness and low emission of a fourth-generation synchrotron light source with fast, sensitive, and high-resolution detectors to collect high-quality data.
