Apparatus for the adaption of a particle beam parameter of a particle beam in a particle beam accelerator and particle beam accelerator with such an apparatus

摘要

A device (3) to adjust a particle beam (10) parameter of a particle accelerator (1) that can operate by accelerating two different particles comprises a beam forming element in a holder that positions the element so that it is arranged in a particle beam in a first operating condition but not in a second operating condition. An independent claim is also included for a particle accelerator for the above.
