摘要
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.
