Examples of three particle accelerators in the US are the isochronous cyclotron, alternating gradient synchrotron and a calutron. An isochronous cyclotron is used for proton therapy. An alternating gradient synchrotron is used to inject heavy ions, and a calutron was used to separate isotopes for the Manhattan project,

An electromagnetic apparatus for separating isotopes of uranium and other elements according to their masses, using the principle of the mass spectrograph. It lost me at 'mass spectrograph'.

The first separation of uranium isotopes was in 1942 in USA - electromagnetic separation (the installation was named calutron).
