    摘要： An acousto-optical modulator apparatus 100 for acousto-optically deflecting a laser beam 1 comprises a gas-filled volume 10 including a working gas 11 and having an input section 12 and an output section 13, being arranged for receiving the laser beam 1 along an incidence light path 2 via the input section 12 and for transmitting the laser beam 1 along a deflection light path 3 via the output section 13, and an ultra-sound transducer device 20 being arranged for creating an ultra-sound field 21 intersecting the incidence light path 2 in an interaction region 14 within the gas-filled volume 10 and creating a periodic density modulation of the working gas 11 in the interaction region 14, wherein the ultra-sound transducer device 20 is capable of deflecting the laser beam 1 in the interaction region 14 by Bragg-diffraction in the ultra-sound field 21, so that the deflection light path 3 has a direction deviating from the direction of the incidence light path 2, wherein the ultra-sound transducer device 20 is configured for focusing the ultra-sound field 21 in the interaction region 14, the gas-filled volume 10 is arranged for keeping the working gas 11 at a working pressure below 10 bar, and the input section 12 and the output section 13 are capable of transmitting the laser beam 1 with a laser centre wavelength included in a wavelength range from mid-IR to XUV. Furthermore, a method of acousto-optically deflecting a laser beam 1 in a working gas 11 is disclosed.

    摘要： Method for irradiation planning of a target volume (34) with a scanned particle beam (20), involving the steps of: defining a target volume (34) arranged inside a body (77), dividing the target volume (34) into a plurality of individually approachable target points (30), defining a number of chronologically consecutive partial irradiation plans, dividing the target points (30) of the target volume (34) into partial quantities (A, B, C, D) on the partial irradiation plans, the partial quantities (A, B, C, D) being distributed along the entire target volume (34), and mutually adjacent target points (30) of the target volume (34) being respectively assigned to different partial irradiation plans.

    摘要： The invention relates to an energy filter device (1, 23) for particle beams (3) of charged particles (3), comprising at least one focusing device (12, 20, 27, 28, 29) and at least one radiation separation device (15, 17, 25, 30, 37). The at least one focusing device (12, 20, 27, 28, 29) is thereby implemented as an energy-dependent focusing device (12, 20, 27, 28, 29).
