Patent Number: 
Section: claims

1. An apparatus for treating a tumor of a patient, comprising:a cancer therapy treatment system, comprising:a synchrotron configured to: (1) accelerate cations at a first time and (2) accelerate electrons at a second time, said synchrotron comprising a turning magnet, said turning magnet comprising:a set of magnet coils wrapped around a magnet core, said set of magnet coils configured to turn the cations;a set of correction coils, said set of correction coils configured to turn the electrons, andsaid set of correction coils wound about said magnet core,said cancer therapy treatment system configured to: (1) treat a first depth of the tumor with the cations and (2) treat the tumor using the electrons. 2. The apparatus of claim 1, further comprising:a set of power supplies connected to said set of magnet coils; andan additional set of power supplies connected to said set of correction coils, said additional set of power supplies configured to correct a magnetic field generated by said set of magnet coils at the first time. 3. The apparatus of claim 1, further comprising:a current controller configured to switch polarity of said turning magnet between the first time and the second time. 4. The apparatus of claim 2, further comprising said cations comprising at least one of:H+; andC6+.
