HESR at fair: status of technical planning

The high-energy storage ring (HESR) of the international facility for antiproton and ion research (FAIR) at GSI in Darmstadt is dedicated to strong interaction studies with antiprotons in the momentum range from 1.5 to 15 GeV/c. Powerful phase-space cooling is needed to reach demanding experimental requirements in terms of luminosity and beam quality. Status and details of technical planning including cryogenic concept will be presented.
