Join CERN on Friday, 4 April to celebrate the achievements and long career of Ugo Amaldi as he turns 90.

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.

Hear all about his outstanding contributions to physics and society on Friday, 4 April, from 2 p.m. in the Main Auditorium. Distinguished scientists will present and discuss his major achievements, including his contributions to particle physics while at CERN, the creation of the TERA Foundation, the design of novel particle accelerators for hadron therapy and his role in setting up an international network for cancer treatment with proton and ion beams. The celebrations will then continue with a drinks reception.

Register now to attend in person. The event is open to all, but registration is required for organisational purposes and to issue CERN access cards for non-CERN attendees. A webcast will also be available for the event.

Read more in an interview with Ugo Amaldi in the latest CERN Courier that draws on his childhood memories and his distinguished career at CERN to offer deeply personal insights into his father Edoardo’s foundational contributions to international cooperation in science.
