MOY02 | NICA Ion Coolider at JINR | 12 |
|
||
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. The status of acceleration complex NICA is under discussion. | ||

MOPSA14 | Production of Superconducting Magnets for the NICA Collider at JINR | 159 |
|
||
The collider structure of the NICA project includes 86 quadrupole and 80 dipole superconducting (SC) magnets. The serial production and testing of these magnets are near to completion at the Veksler and Baldin Laboratory of High Energy Physics of the Joint Institute for Nuclear Research (VBLHEP, JINR). Manufacturing and assembly technology directly affects the quality of the magnetic field. The article describes the technology behind the production of different NICA collider magnets. | ||

WEPSC17 | Vibrating Wire System for Fiducialization NICA Booster Superconducting Quadrupole Magnets | 379 |
|
||
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. | ||

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. | ||

TUB02 | NICA Collider Magnetic Field Correction System | 41 |
|
||
The NICA Collider is a new superconducting facility that has two storage rings, each of about 503 m in circumference, which is under construction at the Joint Institute for Nuclear Research, Dubna, Russia. The influence of the fringe fields and misalignments of the lattice magnets, the field imperfections and natural chromaticity should be corrected by the magnetic field correction system. The layout and technical specification of the magnetic field correction system, the main parameters, arrangements and the field calculations and measurement results of the corrector magnets are presented. The results of dynamic aperture calculation at working energies are shown. | ||

WEB02 | Magnetic Field Measurements for the NICA Collider Magnets and FAIR Quadrupole Units | 71 |
|
||
The magnetic system of the NICA collider includes 86 quadrupole and 80 dipole superconducting magnets. The serial production and testing of the dipole magnets was completed in the summer of 2021. The tests of the quadrupole magnets of the collider and the quadrupole units of the FAIR project have successfully entered the phase of serial assembly and testing at the Joint Institute for Nuclear Research (VBLHEP JINR). One of the important testing tasks is to measure the characteristics of the magnetic field of magnets. The article describes the state of magnetic measurements and the main results of magnetic measurements of NICA collider magnets, quadrupole units of the FAIR project, as well as plans for measuring the following types of magnets of the NICA project. | ||
