abstract = {The Juelich Electric Dipole moment Investigations (JEDI)
collaboration in Juelich ispreparing a direct EDM
measurement of protons and deuterons first at the storage
ring COSY(COoler SYnchrotron) and later at a dedicated
storage ring. Ensuring a precise measurement,various beam
and spin manipulating effects have to be considered and
investigated. Adistortion of the closed orbit is one of the
major sources for systematic uncertainties.
Thereforemisalignments of magnets and residual power supply
oscillations are simulated using the MAD-X code in order to
analyse their effect on the orbit. The underlying model for
all simulationsincludes the dipoles, quadrupoles and
sextupoles at COSY as well as the corrector magnets andBPMs
(Beam Position Monitors). Since most sextupoles are onlyused
during beam extraction,the sextupole strengths are set to
zero resulting in a linear machine. The optics is adjusted
in away that the dispersion is zero in the straight
sections. The closed orbit studies are performedfor
deuterons with a momentum of 970 MeV/c.},
