Improvements in the Beam Dynamics Simulations for the HESR — •Jan Henry Hetzel, Andreas Lehrach, Ulf Bechstedt, Jürgen Böker, Bernd Lorentz, and Raimund Tölle — FZ Jülich, Jülich, Deutschland

The High-Energy Storage Ring HESR is a part of the emerging accelerator complex FAIR (Facility for Antiproton and Ion Research) at the GSI in Darmstadt. The HESR will accelerate and store antiprotons with a momentum range from 1.5 to 15 GeV/c. It will also be suitable for heavy ions with an approximate momentum range from 0.6 GeV/c to 5.8 GeV/c.

In this talk beam-dynamics simulations for the HESR will be presented. The first focusing magnets and the first bending magnets have been delivered and the magnetic field measured recently. These measurements include the estimation of the mulipole components. From these measurement the average harmonic content and its standard deviation throughout the series is estimated. In beam tracking studies for the HESR the multipole errors are diced accordingly. The results of these tracking studies are then used to estimate the dynamic aperture.
