    摘要: The present invention is related to an apparatus and method for hadron beam verification. The apparatus allows to verify a number of different characteristics in a brief time span. The apparatus comprises at least one main degrader element and associated therewith a multiple thickness degrader element. The latter may comprise a number of patches of beam degrading material, the patches having constant but mutually different thicknesses. Alternatively, it may be a wedge-shaped element. By aiming a pencil beam at the various thicknesses, data points can be obtained which allow to make an estimation of the beam range. In addition to this, the apparatus comprises a zone where no degrader material is present, and where a measurement of the spot size can be obtained, without moving or replacing the apparatus.

    摘要: A first aspect of present invention is related to a method for controlling the extraction of ion beam pulses produced by a synchrocyclotron according to an irradiation plan. The synchrocyclotron comprises electrodes configured to be placed in a magnetic field, wherein an alternating voltage is applied between the electrodes, and wherein the frequency of the alternating voltage is modulated in a cyclic manner. The method comprises the steps of starting an acceleration cycle of the synchrocyclotron (12), generating a reference signal (38) when the modulated frequency reaches a predefined value (42), communicating the time, at which the reference signal (38) is generated, to the one or more beam control elements (20, 22), assessing one or more status parameters of the one or more beam control elements (20, 22), wherein the assessment is synchronised with the generation of the reference signal (38), cancelling or proceeding with the extraction of the beam pulse depending on the results of the assessment. A second aspect of the present invention is related to an ion beam extraction system configured to perform the method according to the first aspect of the present invention.

    摘要: An energy degrader (1) for attenuating the energy of a charged particle beam (2), comprising a first energy attenuation member (10) presenting a annular beam entry face (11) and a continuous helical beam exit face (12), a second energy attenuation member (20) presenting a continuous helical beam entry face (21) and an annular beam exit face (22), the first and second helical surfaces facing each other, and a drive assembly configured for rotating the first and/or the second energy attenuation members around respectively a first axis (A1) and a second axis (A2) which are parallel to each other. Such a degrader can have a small moment of inertia, allowing more accurate and faster variation of the beam energy.
