Abstract
The invention comprises a method and apparatus for tuning a charged particle beam path of a charged particle beam system used to treat a tumor of a patient, comprising the steps of: positioning a two-dimensional charged particle detector in a beam line downstream from a magnet pair; operating windings of the magnet pair at a first power level to generate a first magnetic field; measuring a beam position with the first two-dimensional charged particle detector; adjusting a correction magnetic field by driving voltage of a correction coil at a second power level, the second power level less than five percent of the first power level, where the first magnetic field and the correction magnetic field combine to yield an operational magnetic field; and the steps of measuring and adjusting the correction magnetic field changing the operational magnetic field to adjust a measured beam position toward a target beam position.
