Abstract
The present invention improves the accuracy of therapy by checking in real time whether an spread-out Bragg peak (SOBP) width agrees with a desired width during irradiation with a beam. The device for outputting a charged particle beam includes a charged particle beam generatorincluding a synchrotron; a range modulation device such as a range modulation wheel (RMW)which forms a Bragg peak of an ion beam extracted from this charged particle beam generator; an irradiation devicewhich is located in the direction of ion beam propagation of this RMW deviceand includes a dose monitorfor detecting a dose of the ion beam; and an SOBP width calculation devicewhich calculates ion beam Bragg peak formed by the RMW devicebased on a detection value of the dose monitor
