Abstract

The invention comprises a method and apparatus for using a turning magnet of an accelerator of a cancer therapy system, the accelerator comprising first magnet coils and second correction coils wound about a magnet core where: (1) at a first time, the second correction coils are used to correct a magnetic field, resultant from the first magnet coils, used to turn cations and (2) at a second time, after reversing polarity of the correction coils, the correction coils are used to turn anions and/or electrons, the cations and electrons used to treat a tumor of a patient positioned in a treatment position relative to a treatment beam from the accelerator during the first and second time periods.

First claim

The invention claimed is:

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, and
said 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; and
an 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 + ; and
C 6+ .
