Abstract

The High Energy Storage Ring (HESR) is a part of the international project FAIR for the antiproton physics with beam in a momentum range from 1.5 to 15 GeV/c to explore the research areas of hadron structure and quarkgluon dynamics [1]. An important feature of the project is the combination of phase space cooled beams with internal targets. Therefore there are two obvious reasons of beam heating: the target-beam interaction and the intrabeam scattering. Another source of the beam size growth is the high order non-linear resonances. In the paper we investigate the non-linear beam dynamics together with the different schemes minimizing this affect.
