Patent number: 8384054Abstract: Irradiation device for proton and/or ion beam therapy, said device comprising a radiation source, a beam guiding device, and a therapy room comprising a treatment site and an access, wherein the therapy room is arranged in a first plane, and the treatment beam is directed into the therapy room from a second plane above or below the first plane, and oriented towards the treatment site so that the treatment beam is directed away from the access. In the therapy room, a shielding is provided, which is open towards the treatment site and associated with the entrance region of the treatment beam into the therapy room so that the access is arranged on the side of the shielding opposing the treatment site, and a labyrinth leading from the access to the treatment site is provided laterally offset to the treatment beam proceeding in the therapy room and to the shielding.Type: GrantFiled: July 20, 2006Date of Patent: February 26, 2013Assignee: GSI Helmholtzzentrum fuer Schwerionenforschung GmbHInventors: Georg Fehrenbacher, Torsten Radon

Patent number: 7820993Abstract: The invention relates to a multi-layered radiation protection wall for shielding against gamma and/or particle radiation of a reaction site of an accelerator facility, wherein the radiation protection wall comprises a sandwich-like structure with at least a first and a second layer arrangement, wherein the first layer arrangement has at least a primary shielding layer and the second layer arrangement has at least a secondary shielding layer. Thereby, at least one of the first and the second layer arrangements is sub-divided into a plurality of wall segments, whereby a selective disposal is made possible. Thus an increased cost efficiency is achieved and the environmental impact is lowered.Type: GrantFiled: November 19, 2005Date of Patent: October 26, 2010Assignee: GSI Helmholtzzentrum fur Schwerionenforschung GmbHInventors: George Fehrenbacher, Torsten Radon

Patent number: 7655921Abstract: Disclosed is a dosimeter (1) for the detection of neutron radiation within an energy range of 0.025 eV to several hundred GeV, comprising a substantially spherical base body (3) which is used as a moderation body and which comprises hydrogenous material, a detection element (5) which is arranged in the center of the base body (3), and a neutron converter (7) surrounding the detection element (5). The neutron converter (7) comprises metal atoms which convert the energy of the high-energy neutron radiation essentially into neutrons within a suitable energy range. The dosimeter (1) is characterized in that the base body (3) is provided with an access (19) through which the detection element (5) can be introduced into the neutron converter (7) and removed thereform, and in that the neutron converter (7) is embodied in the form of a cylinder.Type: GrantFiled: April 9, 2005Date of Patent: February 2, 2010Assignee: GSI Helmholtzzentrum fur Schwerionenforschung GmbHInventors: Georg Fehrenbacher, Georg Johannes Festag, Frank Gutermuth, Torsten Radon

Patent number: 6927407Abstract: A radiation shielding arrangement for shielding high-energy neutron radiation and gamma radiation from high-energy particle accelerators or storage rings includes a shielding element made of water-containing material, for example with chemically bound water or water of crystallization, in particular gypsum. The water component of the material preferably makes up at least 5, 10 or 20 percent by weight. The hydrogen nuclei or protons contained therein moderate neutrons in a virtually ideal manner because of the almost identical mass and the maximum pulse transformation associated with this.Type: GrantFiled: March 18, 2004Date of Patent: August 9, 2005Assignee: Gesellschaft fur Schwerionenforschung mbHInventors: Willi Brüchle, Georg Fehrenbacher, Torsten Radon, Frank Gutermuth
