Abstract: The matter-antimatter asymmetry may be explained through CP-violation by observing apermanent electric dipole moment (EDM) of subatomic particles. An advanced approachto measure the EDM of charged particles is to apply a unique method of "Frozen spin"on a polarized beam in an accelerator. To increase the experimental precision step bystep and to study systematic effects, the EDM experiment can be performed within threestages: the magnetic ring COSY1, a prototype EDM ring and finally all electric EDMring. The intermediate ring will be a mock-up of the final ring, which will be used tostudy a variety of systematic effects and the main principle of the final ring. In this thesis,simulations towards the optics of the prototype ring are performed and discussed. Thelattice optics with different focusing strengths are generated and studied. Estimations ofbeam losses in the prototype ring for different lattices are performed by using analyticalformulas. These tasks are performed, to minimize systematic errors and enhance beamlifetime in the ring, by optimizing lattice.
