Last week I traveled to Brazil on behalf of DUNE, participating in a DUNE-focused workshop, giving colloquia and attending the opening ceremony of a major new science facility.

FAPESP, the main funding agency in the state of São Paulo, Brazil, organized the one-day DUNE workshop at their headquarters. More than 100 (mostly Brazilian) scientists attended! The director of FAPESP, Brito Cruz, opened the morning session and welcomed everyone, after which I gave an introduction to DUNE. I was joined by Flavio Cavanna, who presented the status of the ProtoDUNE programme at CERN, and Andrzej Szelc of the University of Manchester, who discussed the SBN program and LArIAT. After lunch the meeting focused on the existing neutrino activities in Brazil, then closed with a panel discussion featuring scientists from Brazil, Colombia and Paraguay. This lively and constructive discussion focused on how Brazil and Latin America could come together to collaborate on a major experimental program, such as DUNE.

This extremely impressive meeting underlined Brazil’s interest in DUNE and illuminated the potential for valuable contributions to the experimental effort.

After the workshop, I was honored to give colloquia about our experiment at two of the most highly regarded universities in South America, the Universidade São Paulo (USP) and the Universidade Estadual de Campinas (UNICAMP).

Whilst in Campinas, I had the chance to visit the existing LNLS light source and the construction site for the SIRIUS 4th generation light source – these incredibly impressive facilities underline the highly advanced scientific and technical base that exists in the state of São Paulo.

However, the highlight of my time in Campinas was the opening of the Laboratório de Léptons (the Lepton Laboratory), as featured on UNICAMP TV. (See this month’s At your fingertips.) DUNE’s Ettore Segreto will run this new FAPESP-funded Liquid Argon laboratory, where he and collaborators will be able to further develop the ARAPUCA light detection concept.

Finally, I would like to thank the many physicists in Brazil for their hospitality, and in particular, Ettore Segreto and Ana Machado for teaching me the correct pronunciation of caipirinha…
