	The Nuclotron-based Ion Collider fAcility (NICA) is un-der construction in JINR. The NICA goals are providing of colliding beams for studies of hot and dense strongly interacting baryonic matter and spin physics. The NICA complex injection facility consists of four accelerators: Alvarez-type linac LU-20 of light ions up to 5 MeV/u; heavy ion linac HILAC with RFQ and IH DTL sections at energy 3.2 MeV/u; superconducting Booster synchrotron at energy up 578 MeV/u; superconducting synchrotron Nuclotron at gold ion energy 3.85 GeV/u. In the nearest future the old LU-20 will be substituted by a new light ion linac for acceleration of 2<A/z<3 ions up to 7 MeV/u with additional two acceleration sections for protons, first IH section for 13 MeV and the second one - superconducting for 20 MeV. The status of NICA injec-tion facility is under discussion.

In the work with a circulating ion beam, the effect of reducing the lifetime of the circulating ions was observed when the velocities of the cooling electrons and the cooled ions coincide. The dependences of the electron beam current on the ECS parameters for different electron energy values were experimentally obtained. The specific features of operation of electron gun of the NICA Booster are hollow beam formation and the phenomenon of virtual cathode creation confirmed both experiments and by numerical simulation.

	Injector of NICA accelerating facility based on the Heavy Ion Linear Accelerator (HILAC) is aimed to inject the heavy ions having atomic number A~200 and ratio A/Z - 6.25 produced by ESIS ion source accelerated up to the 3.2 MeV for the injection into superconducting synchrotron (SC) Booster. The project output energy of HILAC was verified on commissioning in 2018 using the beams of carbon ions produced with the Laser Ion Source and having ratio A/Z=6 that is close to the project one. Beams of He¹⁺ ions were injected into Booster in its first run and accelerated in 2020. In 2021 ions of Fe¹⁴⁺ produced with the LIS were injected and accelerated up to 200 MeV/u. Beam formation of Fe ions and perspectives of using LIS for the production the ions with high atomic mass A and ratio A/Z matching to HILAC input parameters are described.

	The NICA (Nuclotron-based Ion Collider fAcility) is anew accelerator complex under construction at the the Laboratory of High Energy Physics (LHEP) JINR. The facility includes two injector chains, two existing superconducting synchrotrons Nuclotron and a new Booster, under construction superconducting Collider, consisting of two rings. The lattice of the Booster includes 48 superconducting quadrupole magnets that combined in doublets. Each doublet must be fiducialized to the calculated trajectory of the beam. Alignment of the magnetic axis is necessary for properly install the magnets at the beam trajectory. The vibrating wire technique was applied to obtain the position of the magnetic axis. A new measurement system has been worked out and produced at the LHEP. The magnetic axis positions of the quadrupole doublets are determined at the ambient temperature. Thepaper describes design of the measurement system, measuring procedure and results of the magnetic axis position measurements.

New accelerator complex is being constructed by Joint Institute for Nuclear Research (Dubna, Russia) in frame of Nuclotron-based Ion Collider fAcility (NICA) project. The NICA layout includes new Booster and existing Nuclotron synchrotrons as parts of the heavy ion injection chain of the NICA Collider as well as beam transport lines which are the important link for the whole accelerator facility. Designs and current status of beam transfer systems in the beginning part of the NICA complex, which are partially commissioned, are presented in this paper.

Injector of NICA accelerating facility based on the Heavy Ion Linear Accelerator (HILAC) is aimed to inject the heavy ions having atomic number A~200 and ratio A/Z - 6.25 produced by ESIS ion source accelerated up to the 3.2 MeV for the injection into superconducting synchrotron (SC) Booster. The project output energy of HILAC was verified on commissioning in 2018 using the beams of carbon ions produced with the Laser Ion Source and having ratio A/Z=6 that is close to the project one. Beams of He¹⁺ ions were injected into Booster in its first run and accelerated in 2020. In 2021 ions of Fe¹⁴⁺ produced with the LIS were injected and accelerated up to 200 MeV/u. Beam formation of Fe ions and perspectives of using LIS for the production the ions with high atomic mass A and ratio A/Z matching to HILAC input parameters are described.

Funding: This work was supported in part by the Russian Foundation for Basic Research, project no.18-02-40097.
Non-destructive ion beam detectors based on micro-channel plates are presented. The design of two-coordinate profilometer situated in the high vacuum volume of the Booster ring is discussed. Experimental data on registration of circulating beam of the Booster in the second run (September 2021) are presented. The possibility of adjustment of the electron cooling system with the help of this detector based on the obtained ex-perimental data is discussed.

The project NICA is being constructed in JINR, to provide collisions of heavy ion beams in the energy range from 1 to 4.5 GeV/u at the luminosity level of 1·1027 cm^-2·s⁻¹. A key element in the collider injection chain is the Booster a cycling accelerator of ions 197Au³¹⁺. The injection energy of particles is 3.2 MeV/u, extraction energy is 600MeV/u. Two Booster RF stations provide 10 kV of acceleration voltage. The frequency range from 587 kHz to 2526 kHz at the operation of the stations in the injector chain. The RF stations were fabricated in the Budker Institute of Nuclear Physics. The main design features and parameters of the first beam tests of the Booster RF system are discussed in this paper.

The NICA (Nuclotron-based Ion Collider fAcility) is anew accelerator complex under construction at the the Laboratory of High Energy Physics (LHEP) JINR. The facility includes two injector chains, two existing superconducting synchrotrons Nuclotron and a new Booster, under construction superconducting Collider, consisting of two rings. The lattice of the Booster includes 48 superconducting quadrupole magnets that combined in doublets. Each doublet must be fiducialized to the calculated trajectory of the beam. Alignment of the magnetic axis is necessary for properly install the magnets at the beam trajectory. The vibrating wire technique was applied to obtain the position of the magnetic axis. A new measurement system has been worked out and produced at the LHEP. The magnetic axis positions of the quadrupole doublets are determined at the ambient temperature. Thepaper describes design of the measurement system, measuring procedure and results of the magnetic axis position measurements.

The Project of complete modernization of the current accelerator complex is in progress in the NRC «Kurchatov Institute». The development of a new booster synchrotron as a part of the injection complex for a new 3-d generation synchrotron light source is included in the Project. The booster synchrotron has 24 dipoles, 60 quadrupoles, 48 sextupoles and 24 correctors. In order to obtain the required field quality, 2D- and 3D-simulations of magnets were carried out. The obtained geometry for each of the magnets is presented in the paper.
