Sirius, the new Brazilian Synchrotron Light Source, is the largest and most complex scientific infrastructure ever built in the country and one of the first fourth-generation synchrotron light sources of the world. It is planned to put Brazil on the leading position in the production of synchrotron light and is designed to be the brightest of all the equipment in its energy class.

Located in the city of Campinas, state of São Paulo, this laboratory, which is part of the Brazilian Center for Research in Energy and Materials (CNPEM), is housed in a 68,000 square meter building. One of the biggest challenges for Sirius is its dimensional, thermal and vibrational stability. Due to that, this building is among the most sophisticated civil works ever built in the country.

To produce Synchrotron Light in a controlled manner, it is necessary to use particle accelerators, which are capable of controlling the movement of high-energy charged particles at speeds close to the speed of light. A Synchrotron Light Source consists of three main sets of particle accelerators, including a Booster and a Storage Ring. This machine functions as a great microscope, which reveals the molecular, atomic and electronic structure of a wide range of materials such as proteins, virus, rocks, plants, metals alloys, etc., and allows research in practically any field, with the potential to solve the major problems in different fields including agriculture, health, oil and gas exploration. This Synchrotron light is generated by electromagnets produced by WEG and are among the most important components of the accelerator. They are the 1001 electromagnets - 211 in the Booster and 750 in the Storage Ring - that guide the trajectory of the electrons inside the equipment.

The partnership of WEG with the National Synchrotron Light Laboratory (LNLS) has already started in 2012 and, since then, the company has been investing in the development of new solutions to meet the project needs. WEG's experience in creating unprecedented products and solutions was of the utmost importance for the Sirius scientists believe in the company's potential to produce state-of-the-art electromagnets and low-power current sources, which guarantee high precision and stability to generate synchrotron light. In addition to this solution, WEG has supplied a power substation with two 15/20/25 MVA oil transformers.
