A particle beam application device and an irradiation device as well as a method for guiding a particle beam

An irradiation device for irradiating a target volume by a particle beam, comprising:

• a source device that generates particles;
• an acceleration device that accelerates the particles and generates the particle beam from the accelerated particles;
• and
• a particle beam application device disposed downstream of the acceleration device that directs the particle beam entering the particle beam application device at the target volume, the particle beam application device comprising:
• a beam shaping device disposed in a beam path of the particle beam that shapes a cross-sectional profile of the particle beam so that the particle beam comprises a line-like cross-sectional profile after the shaping, and
• a controller that varies a relative position between the particle beam and the target volume during the irradiation so that the particle beam is scanned over the target volume.

A method for directing a particle beam at a target volume, comprising:

• shaping a cross-sectional profile of the particle beam so that the particle beam comprises a line-like cross-sectional profile after the shaping;
• changing a beam path of the particle beam in a direction perpendicular to a beam direction of the particle beam and perpendicular to the line-like cross-sectional profile of the particle beam;
• and
• irradiating the target volume by the particle beam.
