Abstract: The 2 MeV electron cooler has been installed in the COSY ring to provide e-cooling of p+ and d+ beams in the entire energy range of the machine and to study the cooling process in the magnetized regime at high energy. Within the cooling section a velocity-matched electron beam is placed coaxially over the beam circulating in the ring. Coulomb interaction between the beams allows heat transfer analogue to heat exchange of gases. The electron beam is guided by a strong longitudinal magnetic field to preserve its quality. The geometry of the beam line however gives rise to higher order dynamics such as larmor rotation and the so called galloping motion, which must be minimized to yield a cold e-beam. Setting up the cooler and delivering a high quality e-beam by adjusting all required parameters manually is a time consuming task and requires a high level of expertise. The presented model under develop-ment shall ease and speed up the adjustment and offer more opportunities for beam control to achieve best possible e-cooling performance.
