Abstract: An apparatus for generating X-rays from electron synchrotron radiation or beams of accelerated ions for ion radiography or ion therapy includes a source of electrons and a source of ions, both of which are connectable to preaccelerators. The preaccelerators supply the appropriate type of charged particle to a synchrotron accelerator which accelerates ions to an energy level that is appropriate for radiography or therapy and which accelerates electrons to a level that generates X-rays by synchrotron radiation in a useful frequency range. The accelerator system also includes a storage ring into which particles are switched and circulated for later use. Electrons are extracted from the synchrotron and injected into the storage ring by fast extraction using a kicker magnet and a septum magnet. They then circulate in the storage ring for periods of hours generating X-rays which may be used for lithography of computer chips with submicron resolution.
