Charged particle beam irradiating apparatus
First Claim
1. A charged particle beam irradiating apparatus for continuously irradiating a charged particle beam along an irradiation line in an irradiation field that is set in an object, comprising:
- a scanning electromagnet that scans the charged particle beam; and
a control unit that controls an operation of the scanning electromagnet,wherein the control unit changes a scanning speed when the charged particle beam is irradiated along the irradiation line such that a peripheral portion of a dose distribution of the charged particle beam is corrected.

Abstract
The present invention provides a charged particle beam irradiating apparatus capable of simply preventing unevenness or reduction in a peripheral portion of the dose distribution of a charged particle beam.
A charged particle beam irradiating apparatus includes scanning electromagnets that scan a charged particle beam and a control device that controls the operations of the scanning electromagnets. In the charged particle beam irradiating apparatus, the control unit changes a scanning speed when the charged particle beam is irradiated along an irradiation line such that a peripheral portion of the dose distribution of the charged particle beam is corrected.
