The beams are provided by a synchrotron which allows for a variation of the ion penetration depth by changing the ion beam energy for each synchrotron cycle. In order to change the beam energy within one synchrotron cycle the accelerator model and data supply model within the control system have been extended extensively. In this first data supply model beam re-acceleration or deceleration between two arbitrary extraction energies is defined. The model defines an additional transition phase, i.e. current/set value patterns between extraction and the re-acceleration yet giving the possibility of setting the beam properties suitable for further acceleration/deceleration. This includes the dipoles, correctors, quadrupoles, sextupoles, KO-Exciter (spill break), and RF. This allowed for the survey and optimisation of the beam properties including possible beam losses of the re-accelerated, transversally blown up beam for arbitrary energy levels.
