“…Magnets with yokes of laminated electrotechnical steel (the 'window frame' type for the dipole, and with poles of a hyperbolic shape for the quadrupole) and coils of a special superconducting cable, cooled by a flow of two-phase helium at the temperature T = 4.5 К, provide a magnetic field at the level В = 2 T and field rising rate up to 4 T/s at cycle repetition frequency of 1 Hz [4]. The main element permitting the provision of such a unique rapidly cycling operation mode of a superconducting device is the composite tubular Nb/Ti/Cu cable [6], proposed at the Laboratory of High Energy Physics (LHEP) and exhibiting a minimum dynamic heat release together with a high superconductor cooling efficiency. Further development of the technology and upgrade of the 'Nuclotron type' magnets permitted the start of designing and constructing magnetic systems for the proton accelerators and the collider within the NICA project and for SIS-100 of the FAIR (Germany) project.…”

The Nuclotron-based Ion Collider fAcility (NICA) is under construction at JINR. The NICA goals are providing of colliding beams for studies of hot and dense strongly interacting baryonic matter and spin physics. The collider experiments will be realized with heavy ions 197 Au 79+ at the center of mass energy range of 4-11 GeV and average luminosity 110 27 cm -2 s -1 . Two modes of operation are foreseen, collider mode and extracted beams with two detectors: MultiPurpose Detector MPD and Baryonic Matter at Nuclotron BM@N. The polarized beams will be operated at the center mass energy range of 12-27 GeV for protons and 4-13.8 GeV for deuterons at average luminosity 110 30 cm -2 s -1 . The accelerator facility of collider NICA consists of following elements: Alvarez-type linac LU-20 of light ions at energy 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 600 MeV/u, existing superconducting synchrotron Nuclotron at gold ion energy 4.5 GeV/n and two collider storage rings with two interaction points. The present status of NICA project is discussed.

“…The external LHCS doping is one of most feasible methods for damping thermal disturbances with typical times >10 ms [2]. Today, this method is used for the construction of dipole magnets of ion collider NICA at the Joint Institute for Nuclear Research (JINR, Dubna, Russian Federation) [3], as well as for superconducting wigglers at Budker Institute for Nuclear Physics (Novosibirsk, Russian Federation) [4].…”

In this paper we report our recent research on thermal stabilization of low-temperature superconducting magnets by means of large heat capacity substances (LHCS). Two samples (lengths ∼100 m) of NbTi composite wires with additional internal filaments made from intermetallic compound PrB6 (5.9–7.3 vol.%) were produced and tested. The design of the wires was similar to that of the conventional MRI sc wires, except for their smaller diameter (0.835 mm instead of 1.345 mm). Our final goal was the investigation of the possibility to minimize (or even eliminate completely) the necessity of MRI magnets training before their commissioning. The comparative stability measurements showed a twofold increase of the minimum quench energies (MQEs) of the doped wires against short heat disturbances. The magnetic field corresponding to the first flux jump increased by 50%. In MQE tests, the PrB6 heat capacity was fully utilized over the course of a 1 ms heat pulse. In the thermomagnetic stability measurements, the efficiency of LHCS doping was about 75% due to the fast evolution of the flux jumps.
