  The new accelerator complex NICA is designed at the Joint Institute for Nuclear Research (JINR, Dubna, Russia) to do experiment with ion-ion and ion-proton collision in the range energy 1-4.5 GeV/u. The planned luminosity in these experiments is 1027cm-2c{-1}. This value can be obtained with help of very short bunches with small transverse size. This beam quality can be realized with electron and stochastic cooling at energy of the physics experiment. The subject of the report is the problem of the technical feasibility of fast electron cooling for collider in the energy range between 0.2 and 2.5 MeV. For the realization of the cooler device BINP team proposes the design that is like to COSY cooler. The main features of this design are the accelerating tube immersed in the magnetic field along the whole length and the strong magnetic field in the cooling section. The physics of electron cooling is based on the idea of the fast magnetized cooling when the ion interacts with Larmour circle and the cooling decrements are improved significantly. The cooling force at strong magnet field was measured at many experiments and can be surely estimated.

A storage ring equipped with an electron cooler is an ideal platform for dielectronic recombination (DR)experiments. In order to fulfill the requirement of DR measurements the system of the precision control of the relative energy between the ion beam and the electron beam should be installed in the electron cooler device. This report describes the project of such system that is designed with section approach like COSY electron cooler. Each section consist of the section of cascade transformer and two power supplies for low and fast detuning of potential of high-voltage terminal. This project can be used in CSRe and future HIAF storage rings.
