摘要：
The invention relates to a particle therapy apparatus having an accelerator for generating a particle beam, a passive energy modulator comprising an absorber element, and a control entity. The control entity is designed to switch between an active adjustment of the energy in the accelerator and a passive energy modulation by the energy modulator, for the purpose of changing the energy of the particle beam from a high energy level to a low energy level in a step-by-step manner. In particular, this has the effect of shortening the dead times when changing between the energy levels.
