	The electron cooler of a 2 MeV for COSY storage ring FZJ is assembling in BINP. The 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 0.1(0.025)- 2 MeV. The electrostatic accelerator consists of 34 individual unify section. Each section contains two HV power supply (plus/minus 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 transformer connected in series with isolating winding. This paper describes the status of the electron cooling assembling.

	Cooler magnetic system for COSY is described. Electron beam energy range is wide (24 keV- 2 MeV), typical bending radiuses of electrons are near 1 m, typical magnetic fields are 0.5 – 2 kG. Under such conditions transport channels with longitudinal magnet field for motion of electrons from high voltage terminal of cascade transformer into cooling section and their return for recuperation are discussed. Results of Hall device measurements are compared with suitable computations. Also some steps were taken for improve of the magnetic field line straightness in the cooling section.
