UNILAC Overview The UNIversal Linear ACcelerator (UNILAC) can accelerate all ion species from protons to uranium to 16% of the velocity of light, i.e., 11.4 MeV/u. Charged ions are provided by three different [...] synchrotron SIS18 for further acceleration or to various experimantal branches. A unique feature of the UNILAC is that some of the Alvarez-cavities can be operated without acceleration, hence also energies as [...] MeV/u of which the exact maximum and minimum value depends on the ions mass to charge ratio. The UNILAC can be operated at a repetition rate of 50 Hz. The beam parameters as ion species, energy, intensity
