	The accelerators of the Facility for Antiproton and Ion Research – FAIR are under construction. The sophisticated system of accelerators is designed to produce stable and secondary beams with a significant variety of intensities and beam energies. FAIR will explore the intensity frontier of heavy ion accelerators and the beams for the experiments will have highest beam quality for cutting edge physics to be conducted. The main driver accelerator of FAIR will be the SIS100 synchrotron. In order to produce the intense rare isotope beams (RIB) at FAIR, a unique superconducting fragment separator is under construction. A system of storage rings will collect and cool secondary particles from the FAIR. Intense work on test infrastructure for the huge number of superconducting magnets of the FAIR machines is ongoing at GSI and several partner labs. In addition, the GSI accelerator facility is being prepared to serve as injector for the FAIR accelerators. As the construction of the FAIR accelerators and the procurement has started, an overview of the designs, procurements plans and infrastructure preparation can be provided.

THPF030	Antiproton Acceleration and Deceleration in the HESR	3758

	The High Energy Storage Ring (HESR) is a part of the future Facility for Antiproton and Ion Research (FAIR) in Darmstadt. The ring is used for hadron physics experiments with a pellet target and the PANDA detector, and will supply antiprotons of momenta from 1.5 GeV/c to 15 GeV/c. To cover the whole energy range a flexible adjustment of transition energy and the corresponding gamma-t value is foreseen. For Injection and Accumulation of Antiprotons delivered from the CR at a momentum of 3.8 GeV/c (gamma=4.2), the HESR optics will be tuned to gamma-t=6.2. For deceleration down to a momentum of 1.5 GeV/c this optic is suitable as well. Stochastic cooling at an intermediate energy is required to avoid beam losses caused by adiabatic growth of the beam during deceleration. For acceleration to 8 GeV/c (gamma=8.6) the optics will be changed after accumulation of the antiproton beam to gamma-t=14.6. For momenta higher than 8 GeV/c the beam will be debunched at 8 GeV/c, optics will be changed to gamma-t=6.2, and after adiabatic rebunching the beam will be accelerated to 15 GeV/c (gamma=16). Simulations show the feasibility of the described procedures with practically no beam losses.
