1. An apparatus configured to control a charged particle beam for irradiation of a tumor of a patient, comprising:

  • a synchrotron configured with an extraction foil, wherein a timing controller times the charged particle beam striking said extraction foil in an acceleration period in said synchrotron resulting in extraction of the charged particle beam at a selected energy;

    a raster beam scanning system configured to scan the charged particle beam across delivery positions while both (1) constantly delivering the charged particle beam at and between the delivery positions and (2) simultaneously varying said selected energy level of the charged particle beam across the delivery positions.
