It's interestig that you mention warships, because the Columbia Cyclotron was one of a group of cyclotrons that were made using war surplus magnets used on the Marconi Transmitters on WW1 battleships. I worked on it in the late 1950s when they were converting it from an internal beam machine to external beam (i.e., bringing the beam out of the primary chamber). After they had done a couple of experiments with that it was supposed to go to the Smithsonian.
I lost touch, but I assumed that it had been removed in the 1960s.
