Caption: Early cyclotron equipment. These are the first two chambers with which US physicists Ernest Orlando Lawrence (1901-1958) and Niels E. Edlefsen (1893-1971) made preliminary and successful tests in 1930 of the magnetic resonance accelerator principle. This led to the development of the cyclotron in 1932. The chambers fitted between the poles of the magnets used to accelerate the particles. The chamber on the left was made mostly of scrap material, including window pane glass, brass, and wax. The chamber on the right was a flattened glass flask silvered on the inside. Photographed at Lawrence Berkeley National Laboratory, USA.Restrictions:
