from Wikipedia, the free encyclopedia

Marcelo Damy de Souza Santos (born July 14, 1914 in Campinas , † July 14, 2009 ) was a Brazilian experimental nuclear physicist .

De Souza Santos studied electrical engineering at the Polytechnic in Sao Paulo from 1933, but switched to physics at the University of Sao Paulo under the influence of Gleb Wataghin . After graduation he went to William Lawrence Bragg at Cambridge University and then worked in sonar research for the Brazilian Navy during World War II . In 1945 he went to the University of Illinois with a grant from the Rockefeller Foundation under Donald William Kerst , the inventor of the betatron . After his return he became an assistant professor in Sao Paulo, where he himself installed a Betatron, the first particle accelerator in Latin America. He was also involved in the commissioning of the first nuclear reactor in Latin America in Brazil - the IEA-R1 research reactor at the University of Sao Paulo, which first became critical in 1957 and is still in operation today. He was one of the founders of the Institute for Nuclear Energy Research (IPEN) in Brazil and was its director from 1956 to 1961 (then called IEA). 1961 to 1964 he was President of the National Nuclear Energy Commission (CNEN) in Brazil. In 1968 he retired from the University of Sao Paulo, but in retirement he built up the physics faculty at the newly founded University of Campinas. He also remained active in research and was professor of nuclear physics at the Catholic University in Rio.

During his time at Wataghin he also researched cosmic radiation.

He was a member of the Brazilian Academy of Sciences.
