Italian experimental physicist
Carlo Franzinetti (March 31, 1923, in Rome – November 28, 1980, in Llantwit Major) was an Italian experimental physicist.
Personal biography.
Carlo Franzinetti was born in Rome, son of Guido Franzinetti, a music critic, and Ada Guastalla, a mathematician and linguist. He was married to Prof. Joan Rees.
During the German occupation of Italy, he was an active member in Resistance Movement. He was one of the leaders of a student group of anti-fascist activists that included Carlo Lizzani, , , and other important figures in the development of post-war Italy.
He graduated from the University of Rome "La Sapienza" in physics with a thesis about projects of construction of an isotope separator based on thermophoresis.
His professional scientific career started when he was 25 (8 May 1948), when he published the article "Emission of Li8 in the Explosive Disintegration of Nuclei" with R.M. Payne in the science journal "Nature".
Cosmic radiation research.
In 1947 he joined the University of Bristol as a research assistant at the H.H. Wills Physical Laboratory, under the guidance of Nobel Laureate Prof. C. F. Powell. Powell's team's research looked at the sub-nuclear structure of matter through the study of cosmic rays with nuclear emulsion.
In 1950 he returned to Rome but he continued his study of cosmic rays. One of the ideas that came out of Powell's team was an expedition in the Mediterranean region to study cosmic radiation at high atmosphere (25 to 30 km) using aerostatic balloons carrying photographic emulsion. Carlo followed the expedition, which took place during the summers of 1952 and 1953 in Naples and in Cagliari, with researchers and students from 13 different physics institutes from various countries. Thirteen balloons were launched, 3 of which were test balloons. Of the other ten, 7 were recovered and 40% of the emulsions had been exposed to cosmic radiation.
Study of neutrinos.
In 1962 he began working in Geneva as a senior physicist at the European Organization for Nuclear Research (CERN). During his time there he played a key role in promoting and working with the Heavy Liquid Bubble Chamber, Gargamelle, where he also conducted his studies of neutrinos. The first report for the request of a common European Heavy Liquid Chamber at CERN was submitted by but, needing the support of Italian and possibly British physicists, he contacted Franzinetti. Franzinetti led the Italian group concerned with the proposal and construction of the Heavy Liquid Chamber, Gargamelle. At CERN he studied, at different energies, with neutrino and antineutrino beams, on different kinds of targets, the production of pions and strange particles, elastic and quasi-elastic interactions, and, through analysis of the interactions of Neutrinos, he studied the form factors of nucleons.
Biophysics.
His interest in biophysics started during his time in Pisa. During his time in Turin he led a biophysics team of students from the Universities of Turin and Pisa, which conducted studies on visual perception. He followed students alongside , a physiologist at the University of Pisa.
