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 

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.

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.

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, 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.

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.

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.

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 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.

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).
