COSY is a cooler synchrotron designed for internal target hadron physics experiments, equipped with both electron cooling system and stochastic cooling system. During the past couple of years, COSY has been evolved into an ideal test facility for accelerator technology development as well as detector development for the Facility of Anti-proton and Ion Research at Darmstadt (FAIR). In addition, COSY has been the test ground for exploring the feasibility of a storage ring based Electric Dipole Moment (EDM) measurement. The proposed precursor experiment of a direct measurement of the EDM of the deuteron at COSY using an RF wien filter by the Jülich Electric Dipole moment Investigation (JEDI) requests significant improvement of beam based measurements as well as beam control. In this paper, first results of measured linear optics based on AT-LOCO are reported. Simulation studies are also discussed.

The renewed availability of heavy ions at CERN for the needs of the LHC programme has triggered the interest of the fixed-target community. The project, which involves sending several species of primary ions at various energies to the North Area of the Super Proton Synchrotron, has now entered its operational phase. The first argon run, with momenta ranging from 13 AGeV/c to 150 AGeV/c, took place from February 2015 to April 2015. This paper presents the status of the project, the performance achieved thus far and an outlook on future plans.

The muon g-2 experiment executed at Brookhaven concluded in 2001 and measured a discrepancy of more than three standard deviations compared to the Standard Model (SM) calculation. A new initiative at Fermilab is under construction to improve the experimental accuracy four-fold. Achieving this goal, however, requires the delivery of highly polarized 3.094 GeV/c muons with a narrow ±0.5% Δp/p acceptance to the g-2 storage ring. In this study, we examine systematic errors that can arise from correlations between muon spin and transverse coordinates for the new g-2 experiment. To achieve this goal we perform end-to-end spin tracking simulations from the production target up to the ring injection point and compare our findings against the results from the Brookhaven experiment. We detail similarities and differences.
