Abstract
The invention comprises a charged particle beam path coupling an injector, synchrotron accelerator, beam transport system, targeting system, and/or patient interface method and apparatus. Preferably, the injector comprises: a negative ion beam source, a two phase ion source vacuum system, an ion beam focusing lens, and/or a tandem accelerator. Preferably, the synchrotron comprises turning magnets, edge focusing magnets, magnetic field concentration magnets, winding and correction coils, flat magnetic field incident surfaces, and/or extraction elements. Preferably, the synchrotron, beam transport system, targeting system, and patient interface combine to allow multi-axis/multi-field irradiation, where multi-axis control comprises control of horizontal and vertical beam position, beam energy, and/or beam intensity and multi-field control comprises control of patient rotation and distribution of delivered energy in and about the tumor in a time controlled, targeted, accurate, precise, dosage controlled, and/or efficient manner.

11. A method for radiation therapy of a tumor of a patient with treatment particles from a charged particle cancer therapy system, comprising sequential steps of:
-
accelerating circulating charged particles in a synchrotron yielding accelerated charged particles; inducing oscillation of the accelerated charged particles yielding oscillating charged particles; extracting the oscillating charged particles from said synchrotron using an extraction foil yielding reduced energy charged particles; and transporting the reduced energy charged particles to the tumor, wherein a charged particle beam path initiates in an injector, wherein said charged particle beam path circumferentially surrounds the charged particles in said synchrotron, wherein at least a portion of said charged particle beam path circumferentially surrounds at least a portion of all of;
(1) the charged particles;
(2) the accelerated charged particles;
(3) the oscillating charged particles; and
(4) the reduced energy charged particles. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
