  Beam cooling plays a key role in the project of the NICA collider. In order to achieve needed luminosity it is important to provide effective cooling during beam accumulation and during experiment. For this purpose, the ring will be equipped with both electron and stochastic cooling systems. The article describes construction of the electron cooler and status of its production by Budker INP.

  The high-voltage power supply system for the electron cooling system of NICA collider ring in the JINR (Dubna, Russia), currently developing at the BINP. The main features are - two accelerating columns with maximum voltage of 2500 kV, stability - 10 ppm, with the load ability 1 mA and nominal current 100 uA. The key points of this design are presented in this article.

  The efficiency of the electron cooling depends on the electron beam quality produced be the electron gun. The characteristics of the electron gun were tested on the test bench with the linear transport channel. For the beam diagnostics, we used beam position monitors alongside with the W-Re wire sensor for 1-D quantitative profile measurements. We also used a high-definition CCD camera with high sensitivity for qualitative 2-D measurements of the electron density distribution via the wire thermal radiation.

  The acceleration and deceleration tubes need the electric power for operation. At BINP different systems were used: many cascade transformers, pressed gas turbine generators, dynamitron system. Experience of using the different systems for powering the high voltage coolers is discussed.

  This work deals with an experimental study of changes in the amplitude of the sum signal induced at pickup stations, which can be associated with the formation of space charge waves arising along the electron beam. In the case of low electron energies, the space charge of the beam can have a significant effect on the interpretation of the obtained experimental data.
