This disclosure relates to apparatuses and methods for the extraction of particle beams while maintaining the energy levels and precision of the particles and the particle beam. Apparatuses and methods for extracting a charged particle beam from a central orbit in a synchrotron are provided, in which a particle beam is deflected from the central orbit. Parts of the deflected particle beam passes through a stripping foil placed in at least parts of the deflected path such that the particles that pass through the foil are stripped of at least one electron. The electron stripped particles and the non-stripped particles may be separated magnetically.
