Automated adjustment of the electron beam line of the 2 MeV Electron Cooler at COSY. — •Arthur Halama and Vsevolod Kamerdzhiev — Forschungszentrum Jülich, Institut für Kernphysik

The 2 MeV electron cooler has an energy range of 25 keV to 2 MeV and is fully magnetized. These particularities and the transport line's geometry proved manual beam line adjustments to be impractical, which led to the request of an automated adjustment. The fundamentals of electron cooling will be presented. Main difficulties of beam adjustments will be touched upon. The latest developments of model-based adjustment methods for the 2 MeV Cooler will be presented supported by experimental results from cooler operations. Emphasis lies on compensation of heating effects, beam orbit adjustment, and achieving acceptable collector efficiencies.
