"An apparatus of the type developed by Lawrence and Livingston was used to produce a beam of high speed deuterons.‥ Since we shall have many occasions in the future to refer to this apparatus, we feel that it should have a name. The term ‘magnetic resonance accelerator’ is suggested.‥ The word ‘cyclotron’, of obvious derivation, has come to be used as a sort of laboratory slang for the magnetic device" (OED).
