(1) The first students to work on the cyclotron in the lab setting modified the magnet to better focus the proton beam.

(2) Michigan State University is the site of a very powerful atom smasher, called a cyclotron .

(3) The antiproton was produced when protons from a cyclotron were used to bombard a copper target.

(4) It was Ernest Orlando Lawrence who invented the first cyclotron back in 1930.

(5) The Berkeley cyclotron created many elements never found in nature - including plutonium, which directly follows neptunium in the periodic table.

(6) The radioactive isotopes must be made in a cyclotron, and because of the short half-lives, the cyclotron must be located at the imaging facility site.

(7) Lawrence used his cyclotron to accelerate deuterons that were then crashed into sodium, producing a therapeutically useful radioisotope of sodium.

(8) Perhaps the most important improvement has been the replacement of an electrical magnet with a series of permanent magnets to generate the cyclotron 's magnetic field.

(9) It was only in 1947 that German physicists were allowed to restart their only cyclotron , a small machine built as part of the wartime fission program at the University of Heidelberg.

(10) The authors are to be commended for a clear and comprehensive description of how cyclotrons , originally used to study nuclear structure and interactions, were redeployed to treat cancer.
