Abstract

The present invention relates to an irradiation device for irradiating an irradiation object with heavy charged particles at an irradiation station, comprising a particle accelerator for providing a particle beam and a swivelling device for swivelling the particle beam impinging on the irradiation object, wherein the swivelling device comprises a carrier pivotable about an axis. In accordance with the invention, the irradiation device is characterized in that the particle accelerator is mounted on the pivotable carrier.
