摘要： A charged particle beam extraction system and method capable of shortening the irradiation time and increasing the number of patients treatable per unit time. The charged particle beam extraction system comprises a synchrotron for cyclically performing patterned operation including four steps of introducing, accelerating, extracting and decelerating an ion beam, an on/off switch for opening or closing connection between an RF knockout electrode and an RF power supply for applying RF power to the RF knockout electrode, and a timing controller for controlling on/off-timing of the on/off switch such that when extraction of the ion beam is stopped at least once during the extraction step of the synchrotron, an amount of the ion beam extracted from the synchrotron in one cycle is held substantially at a setting value.

摘要： A particle irradiation apparatus and a particle beam irradiation method that controls the energy and irradiation dose of a particle beam to form a high dose region having a high uniformity of depth-directional spread (Spread Out Bracici Peak, referred to as SOBP). A SOBP having a steep falling edge of the dose distribution on the deep side from the body surface is formed based on a method of superimposing SOBPs each having a small dose distribution width to form a desired SOBP. An energy-spread-device forms a first SOBP having a small dose distribution width; and an energy spread device 2 forms a second SOBP having a small dose distribution width and a steep falling edge of the dose distribution at the deepest portion from the body surface. The thus formed SOBPs are superimposed to form a SOBP having a length suitable for the target region.
