| 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. | ||

SC Magnets for Project of NICA | |
|
||
| NICA (Nuclotron-based Ion Collider fAcility) is a new accelerator complex designed at the Joint Institute for Nuclear Research (JINR, Dubna, Russia) to study properties of dense baryonic matter. The accelerator complex will consist of three superconducting (SC) rings: the Nuclotron, a booster synchrotron and a two-aperture collider. For the project, it is necessary to produce and test at a helium temperature level (4.5 K) and an operating current of 10 kA of 450 SC magnets. All the magnets contain a cold iron yoke and saddle-shaped superconducting coils made of the hollow NbTi composite SC cable refrigerated by two-phase helium flow at 4.5 K. For this purpose, was created a new factory with a maximum capacity of 12 SC magnets per month. The factory for the production of SC magnets has 8 test-production sections. In the report will show today’s progress in the production of magnets for project, as well as unique cryogenic properties of SC magnets and plans for the production of SC magnets for the NICA project. | ||

| WEB03 | First Experience of Production and Testing the Superconducting Quadrupole and Corrector Magnets for the SIS100 Heavy Ion Accelerator of FAIR | 75 |
|
||
| The fast cycling superconducting SIS100 heavy ion accelerator is the designated working horse of the international Facility for Antiproton and Ion Research (FAIR) under construction at GSI in Darmstadt, Germany. The main dipoles will ramp with 4 T/s and with a repetition frequency of 1 Hz up to a maximum magnetic field of 1.9 T. The field gradient of the main quadrupole will reach 27.77 T/m. The integral magnetic field length of the horizontal/vertical steerer and of the chromaticity sextupole corrector magnets will provide 0.403/0.41 m and 0.383 m, respectively. The series production of the high current quadrupoles and of the individually ramped low current corrector magnets was started in 2020 at the JINR in Dubna and is planned to be completed in 2023. We present the technological challenges that have to be solved from production of the first magnets toward a stable and high rate series production with reliably magnet quality as well as the first test results at operation conditions. | ||
