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.

Sirius is operating with a current of 100 mA in decay mode, with 2 injections per day, providing synchrotron light for 6 beamlines under science commissioning mode

Sirius, the new synchrotron light source from the Brazilian Center for Research in Energy and Materials (CNPEM), is one of the three 4th generation storage-ring-based light sources currently in operation worldwide.

The beamline is dedicated to three-dimensional tomographic imaging with micro and nanometric resolution using high brightness X-rays in the energy range of 22, 39 and 67 keV

MOGNO is one of the beamlines of the Sirius synchrotron light source, of 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 facility is dedicated to obtaining three-dimensional tomographic images with micro and nanometric resolution. Internal structures of various materials can be studied non-invasively, at different spatial resolution, ranging from hundreds of nanometers to tens of micrometers. In addition, it will be possible to subject materials to different mechanical, thermal, or chemical conditions and monitor changes in real time.

This support laboratory allows the preparation of advanced samples and their characterization using electron and optical microscopy techniques, complementary to the experiments in the beamlines

In addition to enabling extremely advanced experiments, the Sirius synchrotron light source, from 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), aims also to provide all the necessary infrastructure for researchers to carry out their investigations.

As such, support laboratories installed around the beamlines will meet the demands of users regarding the preparation and conditioning of samples, carrying out controlled chemical reactions and the use of equipment that may be unavailable at the researcher's institution.

New commissioning stage of Imbuia beamline allows the use of advanced infrared spectroscopy techniques at micro and nano scales

Imbuia experimental station received its first synchrotron beam today, after being connected to the Sirius electron accelerators. It became the only research infrastructure in the world to benefit from infrared radiation generated from a fourth-generation synchrotron accelerator, on the frontier of this type of technology.

The beamline was designed to carry out experiments that allow analyzing the chemical composition of virtually any material and conducting frontier research into new materials, with special emphasis on organic materials, both biological and synthetic. Through spectroscopy techniques, it will allow exploring properties even of materials composed of few atomic layers.

CARNAÚBA’s experimental station has detectors for simultaneous X-ray fluorescence, X-ray diffraction, X-ray excited optical luminescence and X-ray ptychography techniques, and is operating, during commissioning phase, from 6.4 keV to 14 keV

CARNAÚBA is the longest beamline on Sirius, the new synchrotron light source from the Brazilian Center for Research in Energy and Materials (CNPEM), private non-profit organization under the supervision of the Brazilian Ministry of Science, Technology, and Innovations (MCTI). Due to the almost 145-meter distance between the light source and the sample environment, it is possible to produce a high optical demagnification and achieve spatial resolutions in the order of nanometers.

First 3D imaging experiments at Sirius were performed using ptychographic nanotomography

Researchers from the CATERETÊ beamline have succeeded in the very first measurements of 2D and 3D imaging at Sirius, the new Brazilian synchrotron light source of the Brazilian Center for Research in Energy and Materials, a private non-profit organization under the supervision of the Brazilian Ministry of Science, Technology, and Innovations (MCTI).

The CATERETÊ beamline is dedicated to coherent and time-resolved scattering experiments. Experiments such as coherent X-ray diffractive imaging (CXDI) and X-ray photon correlation spectroscopy (XPCS) are at the core of the beamline's activities, as well as time-resolved small-angle X-ray scattering (SAXS).

This call for proposals intends to supply beamtime for the users during the beamline commissioning period

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, we have officially also opened two support laboratories and the scientific computing center. These facilities were officially inaugurated during a ceremony on October 8th.

Paper, which is part of the special issue of the Journal of Molecular Biology, reveals unprecedented details of the maturation process of the main protease of the SARS-CoV-2 virus

The first study with data collected by researchers using Sirius has just been published. Sirius is the state-of-the-art synchrotron light source of 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 work, published in a special issue of the Journal of Molecular Biology, reveals details of the maturation process of the main protease of the SARS-CoV-2 virus.

In addition to the MANACÁ beamline, which is already in scientific commissioning, CARNAÚBA and CATERETÊ are also moving from technical to scientific commissioning and should soon receive the first users in this phase

The operation of the synchrotron light source Sirius in the first semester of 2021 divided the human resources and uptime of the accelerators between machine studies, installation of beamline components, and beamtime for technical and scientific commissioning experiments of the beamlines.
