  The new electron cooler for COSY is built at BINP Novosibirsk. Electron beam commissioning is in progress. Installation in COSY and commissioning with proton beam is scheduled for the beginning of 2012. Beam cooling with up to 3 A of electron current at up to 2 MeV is expected to boost the luminosity in the entire energy range of COSY by counteracting the effects caused by dense targets interacting with the circulating beam. Furthermore, the 2 MeV electron cooler can be used for beam cooling at injection energy in the HESR ring in the FAIR project. The electron beam is guided by a solenoidal magnetic field all the way from the electron gun to the collector. A cascade transformer provides power to numerous high voltage sections, short solenoids, and the collector inside a pressure vessel filed with SF6 gas. Commissioning results are reported.
