The cryomodule allows performing intermediate vacuum-, temperature-, and rf-tests during the fabrication of half-wave resonators. The first experimental results of cryomodule cooling down to liquid nitrogen temperatures are presented and discussed. The pressure and temperature control allow us to estimate the main cooling/heating characteristics of the cryostat at different operation stages. The presented test cryomodule will be used for further development and production of superconductive niobium cavities for the Nuclotron-based Ion Collider fAcility (NICA) injector.

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.

MOPSA17	Automated System for Heating High-Vacuum Elements of Superconducting Synchrotrons of the NICA Complex	168
	A.S. Sergeev, A.N. Svidetelev JINR, Dubna, Moscow Region, Russia A.V. Butenko JINR/VBLHEP, Dubna, Moscow region, Russia
	To obtain an ultrahigh vacuum, it is necessary to preliminarily degass the "warm" sections of the vacuum system of accelerators by prolonged heating to remove water vapor and molecules of other substances adsorbed on the inner surface of the walls of the vacuum chamber. The presented system allows you to heat products with a known unknown heat capacity and thermal conductivity. Some of the accelerators of the NICA complex are supplied without their own heating system and heating is carried out by specialists directly at the accelerator site.

	The report presents the results obtained during the commissioning the Electron Cooling System (ECS) of the Booster, the first in the chain of three synchrotrons of the NICA accelerator complex. The work was performed without an ion beam and with a circulating ion beam He¹⁺. 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.

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 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.

Since 2015 the superconducting (SC) linac-injector development for Nuclotron NICA (JINR, Dubna, Russia) is carried out by the collaboration of JINR, NRNU MEPhI, INP BSU, PTI NASB. This new SC linac is to accelerate protons up to 20 MeV and light ions to 7.5 MeV/u with possible energy upgrade up to 50 MeV for proton beam. This paper reports the current status of the development and manufacturing of superconducting accelerating cavities for a new linear accelerator of the injection complex of the Nuclotron-NICA project.

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.

To obtain an ultrahigh vacuum, it is necessary to preliminarily degass the "warm" sections of the vacuum system of accelerators by prolonged heating to remove water vapor and molecules of other substances adsorbed on the inner surface of the walls of the vacuum chamber. The presented system allows you to heat products with a known unknown heat capacity and thermal conductivity. Some of the accelerators of the NICA complex are supplied without their own heating system and heating is carried out by specialists directly at the accelerator site.

The report presents the results obtained during the commissioning the Electron Cooling System (ECS) of the Booster, the first in the chain of three synchrotrons of the NICA accelerator complex. The work was performed without an ion beam and with a circulating ion beam He¹⁺. 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.
