Ugo Amaldi

Ugo Amaldi joined CERN as a fellow in September 1961. He then spent 10 years at the Italian health institute Istituto Superiore di Sanità in Rome, performing experiments in nuclear and particle physics alongside radiation physics and radiotherapy. Returning to CERN, he helped to discover the rise of the proton–proton cross-section with the energy at the Intersecting Storage Rings, and later led the DELPHI collaboration at the Large Electron–Positron Collider (LEP). In the early 1990s, he founded the TERA Foundation, introducing hadron therapy to Italy. Today, he continues to promote the use of accelerators in cancer treatment and is president emeritus of the National Centre for Oncological Hadrontherapy (CNAO) in Pavia.
