	The low temperature of the electron beam is the key for the high efficiency of the electron cooling, and the strong guiding magnetic field is the means for it. However, high-voltage electron cooling systems come with the challenge of providing the low-temperature beams, as the guiding magnetic field is limited. The electron gun design for the NICA collider cooling systems combines the utilizing the magnetic field and the electrical field constructing, by using the electrodes of special shapes.

	The electron cooling system of the NICA booster is intended for accumulation of the ion beam at the injection energy and for cooling at some intermediate energy value before acceleration to the extraction energy. The system was produced in BINP (Novosibirsk, Russia) and commissioned in the JINR (Dubna, Russia) in 2019. The current status of the electron cooler and the results of its tests are presented in the article.

	The NICA accelerator complex contains two electron coolers, one sits at booster and another at NICA collider. They have requirements for the vacuum of 10^-11 mbar. Despite the coolers have different design the problems of getting vacuum are similar, lack of space along vacuum chambers, presence of the electron beam and oxide cathode usage. The solutions for achieving such a strict requirements are discussed in the article.

	Adjusting unit of longitudinal field coils is necessary element used to obtaining a rectilinear longitudinal field in cooling solenoids of electron cooling machines. Due to limited distance between cooling channels of HV electron cooler for NICA collider, previously used adjusting unit for longitudinal coil couldn’t been applied. Possible orientation of adjusting unit is 90 degrees rotated and gravity force could not preload longitudinal field coil mounting to make adjusting unit working. New design of preloaded coil mounting unit, made by BINP, solves this problem and provides necessary adjusting range and adjusting precision of longitudinal field coils for NICA HV electron cooler’s solenoid.
