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 ) and an independent second electron cyclotron resonance ion source (ECRIS ) for generating heavy and light ions, respectively. Further is enclosed downstream of spectrometer magnet (SP , SP ) for selecting heavy ion species of one isotopic configuration positioned downstream of each ion source (ECRIS , ECRIS ): a magnetic quadrupole triplet (QT , QT ) positioned downstream of each spectrometer magnet (SP , SP ); 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.
