Educational and Amateur Geiger Counter Experiments

Francesco Riggi has been a full professor of Experimental Nuclear and Particle Physics in the Department of Physics and Astronomy at the University of Catania, Italy. He has been working in nuclear physics at low and high energy since 1974 and joined, at its inception, the ALICE Collaboration, a large experiment at the CERN Large Hadron Collider to study nuclear matter under extreme conditions. Within the ALICE Collaboration, he has contributed to the construction of the electromagnetic calorimeter and the silicon pixel detector, investigating the production of multistrange particles, short-lived resonances, and light (anti)nuclei. He has also been active in studying the physics of cosmic rays over the last 20 years, leading several projects concerning the use of cosmic muons in tomographic applications, and has served as a member of the educational project EEE, operating a wide network of cosmic ray telescopes. He is the author or the co-author of more than 600 scientific papers in all such areas and has contributed to various international conferences, as well as acting as a referee for various journals of nuclear and applied physics. As a professor at the Department of Physics and Astronomy in Catania, he has taught several courses in general and nuclear physics for 40 years. He is also the co-author of a textbook on experimental physics and author of the recent book "Messengers from the Cosmos. An Introduction to Cosmic Ray Physics in Its Historical Evolution", Springer, 2023. As a part of the teaching activity in Physics, he has published many papers on educational experiments and has contributed to different outreach activities, including the organization of exhibitions and public events, collaborations with scientific museums, and writing for various newspapers and information blogs.
