  The electron cooler of a 2 MEV for COSY storage ring FZJ is assembled in BINP. Results of experiments with high voltage, with electron beam, cascade transformer for distribution power along acceleration tube will be discussed in this report. The COSY cooler is designed on the classic scheme of low energy coolers like cooler CSRm, CSRe, LEIR that was produced in BINP before. The electron beam is transported inside the longitudinal magnetic field along whole trajectory from an electron gun to a collector. This optic scheme is stimulated by the wide range of the working energies 0.025–2 MeV. The electrostatic accelerator consists of 33 individual unify section. Each section contains two HV power supply (±30 kV) and power supply of the magnetic coils. The electrical power to each section is provided by the cascade transformer. The cascade transformer is the set of the transformers connected in series with isolating winding.

  The construction of the 2 MeV electron cooler at BINP has been completed. After initial testing, the cooler was shipped to Jülich. The installation in COSY is scheduled to begin in April 2013. The report covers the installation and commissioning progress in Jülich. The history of the project is briefly touched on.
