The matter-antimatter asymmetry in the Universe might be understood by investigating the Electric Dipole Moment (EDM) of elementary charged particles. A permanentEDM of a subatomic particle violates time reversal and parity symmetry at the same timeand would be a strong indication for physics beyond the Standard Model. The JülichElectric Dipole moment Investigations (JEDI) collaboration is carrying out a project forthe direct measurement of a permanent EDM of protons and deuterons. For this reason adedicated electrostatic storage ring is in development. As an intermediate step a prototypering is being developed to demonstrate sucient beam lifetime and Spin Coherence Time(SCT) in a pure electrostatic ring as well as in a storage ring with combined electric andmagnetic bending elements. The scope of this thesis is the simulation of a prototype ringwith combined electric and magnetic bending elements and the investigation of the inuence of chromaticity on the SCT. It will be shown that a vanishing horizontal and verticalchromaticity does not cause the maximal SCT, as one might expect from initial theoreticalconsiderations. The optimal sextupole settings have to be determined individually for eachworking point as will be demonstrated within this thesis. |
