Abstract
The invention comprises a charged particle beam acceleration method and apparatus used as part of multi-axis charged particle radiation therapy of cancerous tumors. The accelerator includes a synchrotron having advances in turning magnets, edge focusing magnets, magnetic field concentration magnets, and extraction and intensity control elements that minimize the overall size of the synchrotron, provide a tightly controlled proton beam, directly reduce the size of required magnetic fields, directly reduces required operating power, and allows independent energy and intensity control of extracted charged particles from the synchrotron.
