  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.

  Construction of measurement system is presented. The system is based on special magnetic sensor (compass) with a mirror attached to the compass needle. The needle with the mirror are suspended on gimbal suspension and can rotate in two directions. Measuring reflected laser beam deflection one can measure field line straightness with accuracy up to 10-6 rad. The compass is installed inside vacuum volume of the cooling section on special carriage that moves on rail along the section via special tape. To calibrate the compass special test bench was made. The calibration procedure allows to determine and to diminish compass inaccuracy appeared during manufacture and assembling. Results of calibration of the compass on the test bench are presented.
