Publication number: 20160314929Abstract: 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.Type: ApplicationFiled: April 20, 2016Publication date: October 27, 2016Applicant: Cryoelectra GmbHInventors: Jürgen Drees, Helmut Piel

Patent number: 8933421Abstract: 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.Type: GrantFiled: April 21, 2009Date of Patent: January 13, 2015Assignee: Varian Medical Systems Particle Therapy GmbHInventors: Jürgen Drees, Helmut Piel
