  • Publication number: 20170007848
    Abstract: A particle beam treatment system having a beam generation unit for generating a beam of charged particles, in particular ions, preferably protons, and having a beam guidance system. The generic beam guidance system takes up less space but can provide comparable or even improved beam properties because, in part, the beam guidance system seen in the direction of the beam of charged particles and behind the beam generation unit has at least one solenoid magnet as a beam shaping unit, and the at least one solenoid magnet of the beam guidance system is a superconducting solenoid magnet.

  • Publication number: 20160314929
    Abstract: The invention relates, inter alia, to a beam guidance system for guiding a beam of charged particles with a magnetic beam deflection unit, wherein the magnetic beam deflection unit has an entry side for entry of the beam of charged particles into the magnetic beam deflection unit in a direction of entry, wherein the magnetic beam deflection unit has an exit side for exit of the beam of charged particles from the magnetic beam deflection unit in a direction of exit. A further aspect of the invention relates to an advantageous particle beam therapy system. The problem of providing improving beam properties and at the same time reducing the amount of space required is solved in that the entry side of the magnetic beam deflection unit is, at least in sections, aligned substantially parallel to the exit side of the magnetic beam deflection unit.

  • Patent number: 8933421
    Abstract: A particle beam therapy system including an accelerator for making a beam of charged particles available, a beam guiding unit supplying the beam to a treatment location starting from the accelerator, and at least one beam property monitor arranged along the beam path. A control unit communicates with the beam property monitor and guiding unit and determines deviations of actual properties from desired properties of the beam and transmits control signals for adapting the beam properties to the guiding unit, using said deviations. Precise beam guidance is achieved by arranging the beam property monitor on the periphery of the beam perpendicular to the beam path such that the beam properties are detected due to their direct interaction with particles of the beam in the halo region and/or indirectly by electromagnetic interaction. A method for a beam of charged particles in a particle beam therapy system is also disclosed.

  • Publication number: 20110098522
    Abstract: A particle beam treatment system comprising a beam generating unit for generating and adjusting the kinetic energy of a beam of charged particles, comprising at least two beam guide units for feeding the beam of charged particles to a treatment location associated with the respective beam guide unit, wherein each beam guide unit comprises at least one beam deflection unit and/or at least one beam forming unit. The at least two beam guide units are designed for different areas of the kinetic energy of the charged particles such that the at least one beam deflection unit and/or the at least one beam forming unit of each beam guide unit are tailored to the energy of the particles and/or to beam characteristics of the particle beam. The invention further relates to a particle beam treatment method and use of the particle beam treatment system.
