  • Patent number: 7138771
    Abstract: The present invention relates to an apparatus for pre-acceleration of ions and optimized matching of beam parameters used in a heavy ion application comprising a radio frequency quadruple accelerator (RFQ) having two mini-vane pairs supported by a plurality of alternating stems accelerating the ions from about 8 keV/u to about 400 keV/u and an intertank matching section for matching the parameters of the ion beam coming from the radio frequency quadruple accelerator (RFQ) to the parameters required by a subsequent drift tube linear accelerator (DTL).
    Type: Grant

  • Patent number: 7081723
    Abstract: The invention relates to a drift tube accelerator (1) for the acceleration of ion packets in ion beam acceleration systems, wherein a housing (2) consists of a longitudinally divided three-part vacuum tank (3) having a central unit (4) and a lower half-shell (3) comprising a structured lower steel block (15) and an upper half-shell (6) comprising a structured upper steel block (19). (The cavity arranged between the central unit (4) and the structured steel blocks (15, 19) has at least two acceleration regions (24, 25), between which there is arranged a magnetic focussing device (17), which focuses the ion beam from one region (24) to the next region (25).

  • Patent number: 6809325
    Abstract: The present invention relates to an apparatus for generating, extracting and selecting ions used in a heavy ion cancer therapy facility. The apparatus comprises an independent first (ECRIS 1) and an independent second electron cyclotron resonance ion source (ECRIS 2) for generating heavy and light ions, respectively. Further is enclosed downstream of spectrometer magnet (SP1, SP2) for selecting heavy ion species of one isotopic configuration positioned downstream of each ion source (ECRIS 1, ECRIS 2): a magnetic quadrupole triplet (QT1, QT2) positioned downstream of each spectrometer magnet (SP1, SP2); a switching magnet (SM) for switching between high-LET ion species and low-LET ion species of said two independent first and second ion source.
