The problems of development of high energy electron coolers are discussed on the basis of the existing experience. Necessities of electron cooling application to NICA collider are considered and the project parameters of the electron cooler at NICA collider are presented. Electron cooler of the NICA Collider is under design and development of its elements at JINR. It will provide the formation of an intense ion beam and maintain it in the electron energy range of 0.5'2.5 MeV. To achieve the required energy of the electrons all the elements of the Cooler are placed in the tanks filled with sulfur hexafluoride (SF6) gas under pressure of 6 atm. For testing the Cooler elements the test bench «Recuperator» is used and upgraded. The results of testing of the prototypes of the Cooler elements and the present stage of the technical design of the Cooler are described in this paper.

Nuclotron-based Ion Collider fAcility (NICA) is the new experimental heavy-ion complex being constructed at Joint Institute for Nuclear Research, Dubna. Main purpose of the project is to provide experiment on colliding heavy ion beams (Au) for study of manifestation of hot and dense strongly interacting baryonic matter. The construction of the accelerator complex is actively performed: new 3.2 MeV/u heavy-ion linear accelerator (HILac) is now under commissioning, serial production of Booster synchrotron elements is going in schedule. Systems for collider had been prototyped and start of serial production is in 2015. Beam cooling systems are suggested for application at NICA. The Booster equipped with 35 keV electron cooling system. Two beam cooling systems: stochastic and electron, will be used in the collider. Parameters of cooling systems, proposed scenario of collider operation, design intended to achieve required average luminosity of the order of 10²⁷cm^-2s^-1, start-up version of the complex for 2019 are presented.

The project of the Low Energy Positron Toroidal Accumulator (LEPTA) is under development at JINR. The LEPTA facility is a small positron storage ring equipped with the electron cooling system. The project positron energy is of 2 ' 10 keV. The main goal of the facility is to generate an intense flux of positronium atoms ' the bound state of electron and positron. Storage ring of LEPTA facility was commissioned in September 2004 and is under development up to now. The positron injector has been constructed in 2005 / 2010, and beam transfer channel ' in 2011. By the end of August 2011 the experiments on injection into the ring of electrons and positrons stored in the trap were carried out. In 2012 - 2015, the LEPTA trap optimization and new experiments on accumulation of electrons and positrons in the trap has been performed. Furthermore new cooler for positrons source has been designed and manufactured, its assembling is in progress. The recent results are presented here.
