Engineering solutions for its basic elements are presented. The measurements of the electron cooler magnetic system and the influence of the adjacent solenoids in the cooling section on the resulting magnetic field are described. The potential opportunities to improve parameters of the experiments with ion beams using the electron cooling system are discussed.
