Abstract :
The High Energy Storage Ring (HESR) of FAIR project consists of two achromatic arcs and two dispersionless straight sections. Due to the multifunctional purpose of the straight sections their contribution into the total chromaticity of the first and second order exceeds the arc´s contribution and can affect on the non-monochromatic beam dynamic aperture. We investigate the optimum sextupole and octupole scheme correction for monochromatic and non-monochromatic beam to reach the larger dynamic aperture.
