1. A method for use of a charged particle accelerator, comprising the steps of:
- providing a synchrotron;
applying a first acceleration voltage to an inductor via an electrical circuit during an acceleration period of said synchrotron, said inductor configured to generate a magnetic field through a portion of said synchrotron;
opening a first switch in said electrical circuit to add a first resistor to said electrical circuit during a recovery time period after said acceleration period, wherein said first resistor results in a decrease of said voltage to said inductor.

Abstract
The invention comprises a charged particle cancer therapy system or synchrotron system using one or more switches to introduce a corresponding one or more resistors into a circuit linking a power supply to a magnet or an inductor during an applied power recovery phase between acceleration cycles of the synchrotron, which reduces time of reduction in power from an active applied power to a power suitable for use with a subsequent injection of charged particles into the synchrotron.
