Abstract
A charged particle beamwhich enters a final bending electromagnetafter traveling through quadrupole electromagnetstravels through the final bending electromagnetin an arc shape path by increasing or decreasing a bending magnetic field generated in the final bending electromagnet, with a pre-determined period for example and is scanned in an X-direction. The charged particle beamscanned in the X-direction is scanned in a Y-direction while traveling through a Y-direction Wobbler electromagnet. Consequently, the charged particle beamis scanned in the X-direction and the Y-direction, and the targetis irradiated with the charged particle beamso that a round field is drawn, for example.
