TRANSPORT OF NON-SYMMETRIC ION BEAMS IN ROTATING ION-OPTICAL SYSTEMS

Márius Pavlovič

   Transport of ion beams in rotating ion-optical systems is discussed in the paper. Special attention is paid to the transport of beams with different emittances in the horizontal and vertical plane (non-symmetric beams). Summary of theoretical matrix analysis of the problem is presented. Different matching methods are reviewed and compared. A novel solution that has recently been granted a US-Patent is presented. An example is given for transport of ion-therapy beams through an isocentric rotating gantry. Theoretical considerations and results are, however, valid for other types of rotating systems, as well.

Keywords: beam-transport, emittance, gantry, ion optics, ion therapy
