Results of testing of the collector with Wien filter in the 2 MeV electron cooling system for COSY synchrotron are presented. Efficiency of a collector in high voltage electron cooling devices is important from the point of view of the load on high voltage power supply, radiation safety and vacuum conditions in the system. The collector for 2 MeV COSY cooler is supplemented with Wien filter which allows increase efficiency of the system by deflection secondary electron flux in crossed transverse electric and magnetic fields. Results of tests show that such solution provides efficiency of recuperation in the cooler up to 10^-5. After tests some changes were made in the construction of the Wien filter to improve quality of the collector performance.

The goal of the cooling system of the NICA collider is to meet the required parameters of ion beams in energy range of 1–4.5GeV/u that corresponds to the 0.5–2.5 of the electron MeV. The electron cooler is developed according to the available world practice of manufacturing of similar systems. The main peculiarity of the electron cooler for the NICA collider is use of two cooling electron beams (one electron beam per each ring of the collider) that never has been done. The acceleration and deceleration of the electron beams is produced by common high-voltage generator. The cooler consist of three tanks. Two of them contain acceleration/deceleration tubes and are immersed in superconducting solenoids. The third one contains HV generator. The scheme of the electron cooler, its main parameters and operation regime are presented.
