Between 1960 and 1965, the first Italian cyclotron was designed and built at the Institute of Physical Sciences of the University of Milan. It belonged to the category of fixed frequency cyclotrons, variable azimuth field (A.V.F.) and was of the Thomas strong focus type. A special shed and other buildings were built to house the machine and the research laboratories. The machine worked until the early 1980s and was subsequently dismantled when construction of the superconducting cyclotron was started in Segrate. The 1: 5 scale model of the cyclotron is kept at the Museum of Science and Technology in Milan. It was created at the time, in particular, to study the most suitable and economical shape of the magnets to guarantee the necessary field.
