Caso has left us, after having struggled against a strong disease with courage for a long year; he had succeeded also in recovering partially, coming back to work with his usual enthusiasm and inducing all of us to hope that he was getting out of his problems.
Carlo obtained his Laurea degree at the University of Genoa in 1964 in the group led by Professor Giovannina Tommasini and since then he devoted his scientific activity to particle physics, performing experiments at CERN, where he spent time also as Fellow and Scientific Associate.
At the beginning, within the Genoa Group, he did research with liquid hydrogen bubble chambers in order to study the properties of the production and decay of both baryon and meson resonances. He then participated to the European Hybrid Spectrometer collaboration (EHS), obtaining many important results, among which the first high precision measurement of the lifetime of the charmed D-mesons. With the arrival of LEP Carlo and his group shared the big adventure of the DELPHI experiment with the design and construction of a large number of modules for the electromagnetic calorimeter HPC and many significant contributions to the experiment regarding the physics of beauty and the search for the Higgs boson.
After LEP Carlo devoted himself entirely to the preparation of the experimental activity at the new CERN Collider, the Large Hadron Collider (LHC); the Genoa group was strongly involved in the design and construction of the vertex detector of the ATLAS experiment, and Carlo has given important personal contributions to this
