Abstract: The Cooler Synchrotron (COSY) is a particle accelerator and storage ring operatedby the Institute for Nuclear Physics (IKP) at Forschungszentrum J ̈ulich. Thefacility provides polarized and unpolarized beam sources, a cyclotron, an injectionbeam line and the synchrotron itself, which besides many other features containselectron and stochastic cooling systems. The injection beam line of COSY has beeninjecting 45 MeV proton and 76 MeV deuteron beams from the cyclotron into thering since 1991. The optimization of the injection is done by hand and, therefore,the opportunity for improvement is substantial. Currently, a new approach is beingdeveloped in order to make this process of optimization more effective.The main objective is to rely on a thoughtful study of the injection process and sim-ulation tools to set the injection beam line parameters in order to achieve desirableresults and match the synchrotron’s properties at injection. The different necessarysteps to reach this goal are discussed. The process includes the characterization ofthe beam in the injection beam line, an analysis of the injection beam line latticeand the optimization of its sections using the Bmad software, the calculation of itsmain parameters and, finally, the matching of the desired ones at injection.In the end, the obtained results are shown and the conclusions are presented. Thework finishes with an outlook which describes the possible steps to take in any futuredevelopment related to the injection process in COSY.
