DESIGN OF IBA CYCLONE ® 30XP CYCLOTRON MAGNET

IBA is currently developing an evolution of its famous Cyclone ® 30 cyclotron. The Cyclone ® 30XP cyclotron will be a multi-particle, multiport cyclotron capable of accelerating alpha particles up to 30 MeV (electrostatic extraction), deuteron (D - ) beams between 7.5 and 15 MeV and proton (H - ) beams between 15 and 30 MeV (stripping extraction). The magnet system has been updated with improved versions of IBA Cyclone 18/9 and Cyclone 70 features. At first, coil dimensions have been updated in order to raise the free space in the median plane to allow mounting a retractable electrostatic deflector system for the extraction of the alpha particle beam. Gradient corrector pole extensions, have been added to ease the alpha beam extraction. Finally, compensation for relativistic effects between H - (q/m=1/1) and D -
