|
||
The Nuclotron-based Ion Collider fAcility (NICA) is under 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 accelerator facility of collider NICA consists of following elements: acting Alvarez-type linac LU-20 of light ions at energy 5 MeV/u, constructed a new light ion linac of light ions at energy 7 MeV/n and protons at energy 13 MeV, new acting heavy ion linac HILAC with RFQ and IH DTL sections at energy 3.2 MeV/u, new acting superconducting booster synchrotron at energy up 600 MeV/u, acting superconducting synchrotron Nuclotron at gold ion energy 4.5 GeV/n and mounted two Collider storage rings with two interaction points.

Commissioning of Electron Cooling System of the NICA Booster Synchrotron | |
|
||
At JINR, within the framework of the NICA project at the Booster synchrotron, the Electron Cooling System (ECS) of the ion beam has been built. The SEO was designed and manufactured at the Budker Institute of Nuclear Physics of SB RAS. The setup is designed to form the required parameters of the ion beam. The report presents a description of the main systems of the installation, presents the modernization of the automated control system, including a thermometry subsystem of the magnetic system, a subsystem for blocking and access control. The results of testing the ECS operation with the modernized equipment as part of the NICA Booster are presented. | ||

TUPSB04 | Features of the Electronic Cooling System of the NICA Booster | 236 |
|
||
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. | ||

WEA01 | Beam Transfer Systems of NICA Facility: from HILAC to Booster | 61 |
|
||
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. | ||

MOY01 | The NICA Complex Injection Facility | 7 |
|
||
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. | ||

WEPSC15 | Barrier Station RF1 of the NICA Collider. Design Features and Influence on Beam Dynamics | 373 |
|
||
This paper reports on the design features and con-struction progress of the barrier bucket RF systems for the NICA collider being built at JINR, Dubna. Each of two collider rings has three RF systems named RF1 to 3. RF1 is a barrier bucket system used for particles capturing and accumulation during injection, RF2 and 3 are resonant systems operating at 22nd and 66th harmonics of the revolution frequency and used for the 22 bunches formation. The RF systems are de-signed by Budker INP. Both RF1 stations were manu-factured, delivered to JINR and tested at the stand. The test results are presented in the article, as well as some results of calculating the effect of the RF1 system on the beam dynamics. | ||
