  schema:description "Proton centres are built around one of three accelerators, a cyclotron, a synchrotron or a compact synchrocyclotron, feeding one or several treatment rooms through magnets and a rotating gantry the size of a house. Single-room systems have cut the price of entry, and upright treatment chairs may shrink the building again."@en ;
