  For more than three decades, GSI has successfully operated the Universal Linear Accelerator (UNILAC), providing ions from protons to uranium at energies from 3 to 11 MeV/u. The UNILAC will serve for a comparable period as injector for the upcoming FAIR facility which will ask for short pulses of high peak currents of heavy ions. The UNILAC Alvarez-type DTL has been in operation since the earliest days of the machine, and it needs to be replaced to assure reliable operation for FAIR. This new DTL will serve the needs of FAIR, while demands of high duty cycles of moderate currents of intermediate-mass ions will be met by construction of a dedicated superconducting cw-linac. FAIR requires additionally provision of primary protons for its pbar physics program. A dedicated proton linac is under design for that task. The contribution will present the future linacs to be operated at GSI. Finally we introduce a novel method to provide flat ion beams for injection into machines having flat injection acceptances.

  We present the concept of a small superconducting CW accelerator with multi-turn energy recovery. This machine, the Mainz energy recovering superconducting accelerator (MESA), is intended to serve for particle physics experiments in the energy range 100-200MeV.

A status report of the 1.6 GeV electron accelerator MAMI-C is given together with an outlook towards its future operation. We describe problems which are imposed by some aging technical subcomponents in the first stages which have in part been in operation for almost 30 years. We present measures how to sustain the achieved extremely high reliability during the upcoming new research programs which are foreseen to last at least for one more decade.
