CALIBRATION OF LINEAR OPTICS OF COSY BASED ON ORM DATA
The COoler SYnchrotron in Jülich is a well suited accelerator for a precursor experiment on the direct measurement of the Electric Dipole Moment (EDM) of the deuteron (see* and references within). It provides polarized and unpolarized proton and deuteron beams in the momentum range between 0.3 GeV/c...

The COoler SYnchrotron in Jülich is a well suited accelerator for a precursor experiment on the direct measurement of the Electric Dipole Moment (EDM) of the deuteron (see* and references within). It provides polarized and unpolarized proton and deuteron beams in the momentum range between 0.3 GeV/c and 3.65 GeV/c**, allows for phase space cooling and is highly flexible with respect to ion-optical settings***. Unfortunately, a model independent linear optics measurement is not possible and so far the existing MAD-X model of COSY does not provide an agreement with the actual machine parameters that is required by future experiments, such as the EDM experiment. Significant deviations with respect to the working point and linear optics have been reported****. As shown in*****, a MAD-X based LOCO (Linear Optics from Closed Orbits) algorithm in a C++ program was successfully developed and carefully benchmarked. This contribution presents the application of the new program on measured ORM data and its capabilities in calibrating linear optics as well as reconstructing machine imperfections such as gradient errors of quadrupole magnets and calibration factors of BPMs and steerers. |
