The fourth Cateretê Workshop will be held at the brand new Sirius building of the Brazilian Synchrotron Light Laboratory (LNLS), located at the Brazilian Center for Research in Energy and Materials (CNPEM) in Campinas, state of São Paulo, in Brazil.


The Brazilian Synchrotron Light Laboratory (LNLS) operates the only synchrotron light source in Latin America, providing high brilliant light from infrared to X-rays for the analysis of organic and inorganic materials. Designed and built with Brazilian technology, LNLS was inaugurated in 1997 as an open facility to the scientific and industrial communities across the country and abroad.


LNLS is currently engaged in the conclusion of Sirius, the next Brazilian synchrotron light source. It is planned to be a state of the art fourth generation machine, designed to be one of the most advanced in the world. Its ultra-low emittance and thus high brightness will open up new perspectives for research in many fields such as material science, structural biology, nanoscience, physics, earth and environmental science, cultural heritage, among many others. The first stage of Sirius Project was delivered in November, 2018 and it is planned to be open to the scientific committee in 2020.


The Brazilian Center for Research in Energy and Materials (CNPEM) is a private nonprofit organization located in Campinas, Brazil, which is funded by the Ministry of Science, Technology & Innovation (MCTIC). It is dedicated to cutting-edge research in materials, nanosciences, life sciences, physics, and chemistry through four National Laboratories: Synchrotron (LNLS), Biosciences (LNBio)Biorenewables (LNBr) and Nanotechnology (LNNano). The four laboratories are open facilities for external users and companies, from Brazil and abroad. They also have teams of researchers to provide support for projects, as well as to conduct joint research programs in biomass, green chemistry, drugs and cosmetics development, characterization of advanced materials, catalysts, etc.

Other tips and aditional information

  • Tipping: tipping is not as widespread or regulated in Brazil as it is in other parts of the world. Tipping is your prerogative, a reward for service. It is customary to tip hotel porters, and a gratuity of about 10% is usual in restaurants if good service is received.
  • Disabled facilities:if you require disability specific facilities, please notify the secretariat.
  • Household Voltage in Brazil You may need adapters to plug in your electric/electronic devices. The sockets in the hotel are mostly of the type shown in the picture which accepts both US flat plugs as well as thin European plugs. The voltage in the rooms is 220 Volts, but you may encounter some outlets at 110 Volts. Beware of this bi-voltage danger in all of Brazil!
