COSY Experience of Electron Cooling

Abstract

The 2 MeV electron cooling system for COSY-Julich has highest energy for the electron cooler with strong longitudinal magnetic field. During operation the cooling process was detailed investigated at 908 keV energy of electron beam. The proton beam was cooled at different regimes: RF, barrier bucket RF, cluster target and stochastic cooling. This article deals with the experience of electron cooling at high energy
