“…The collider itself will consist of two SC rings of racetrack shape, with maximum magnetic rigidity of 45 Tm and a circumference of 503.04 m. Two IPs are foreseen in opposite straight sections of the NICA collider -one for heavy-ion studies with the multi-purpose detector (MPD) [392] and another for polarized beams, housing the spin physics detector (SPD) experiment [393]. The maximum field of the collider dipole superferric magnets, which use iron to shape the field and superconductors to excite it, is 1.8 T [387] -see Fig. 16.…”

“…The most complex ones are three individually constructed modules which are intended for injection, beam extraction from SIS100, and beam transfer from SIS100 into SIS300 [22]. At the present time, two structural variants of a module with quadrupole lenses are being examined [23,24]. The final choice must be made on the basis of tests.…”

At the beginning of the 1970s, the stage of development and assimilation of magnetic and accelerator technologies based on superconductivity started in the leading scientific centers in world which were studying the fundamental problems of nuclear physics and the structure of matter. Superconductivity for developing magnets for the proton synchrotron with field amplitude much greater than the limit for ordinary magnets (B~ 2 T) was harnessed at Fermi Lab (Batavia, USA). The magnetic system of the Tevatron with field amplitude in the working aperture to 4.7 T, placed inside the synchrotron tunnel at energy 500 GeV, made it possible to double the energy of the accelerator. The field in the Tevatron magnets is formed by a multi-turn winding, fabricated on precision equipment. The accuracy of its geometric dimensions determines the quality of the magnetic field in the aperture. Superconducting magnets of this type in their modern form were used in the designs of other accelerators and were termed cos θ magnets. The magnets are cooled successively; the cool-down time of the magnetic system to the working temperature is weeks.A precision cos θ magnet, cryostat with a vessel for liquid helium, heat screen, vacuum jacket, and anchoring of the magnet are integral parts of an extremely labor-intensive, metal-intensive, and expensive cryogenic-magnetic system. Magnets of a new type [3] were developed in the High-Energy Laboratory at the Joint Institute for Nuclear Research (OIYaI) to considerably simplify and reduce the cost of the construction of the superconducting magnet and its cryostating system for the Nuclotron -a specialized synchrotron for relativistic nuclei [1, 2]. Their fundamental difference lay in the use of a magnetic with a window-frame cross-sectional geometry instead of the cos θ precision magnet and a specially developed tubular superconducting cable, intended for pulsed magnets with rapid ramping of the field, instead of the flat superconducting Rutherford cable. In the case of tubular cable, as opposed to Rutherford cable, there is no coil or frame electric insulation in the path of heat flow from the superconductor to the helium; this improves considerably the conditions for cryostating of the superconductor. In addition, the use of two-phase helium as the cryogenic coolant makes the conditions for cooling the superconductor in the tubular cable of the pulsed magnets of the accelerator unique, making it possible to operate with record high field ramping 4 T/sec and higher [4]. On the whole, the concept adopted made it possible to minimize the transverse cross section of the Nuclotron magnet, eliminate the helium vessel inside the cryostat, secure an operating regime with field rise and fall rate 4 T/sec, economize on materials and power supply, simplify the external infrastructure, and most importantly organize the fabrication and testing of the magnets on the basis of the production capacity of OIYaI.OIYaI Nuclotron -SIS100 Prototype. The development of the Nuclotron, a superconducting, strongly focus...
