NICA is a new accelerator complex being under design and construction at the Joint Institute for Nuclear Research (JINR) in Dubna. Full-size prototype dipole and quadrupole magnets for the booster synchrotron and the NICA collider have been designed, manufactured and tested. The magnets are based on a cold window frame iron yoke and a saddle-shaped superconducting winding made from a hollow NbTi composite superconducting cable cooled with a forced two-phase helium flow at T = 4.5 K. The maximal operating magnetic field in the aperture is 1.8 T. The magnetic field ramp rate of 1.2 T/s should be achievable. The quench history, AC losses as a function of the magnetic field ramp rate and pressure drop in the cooling channels of the magnets at different pulsed operation modes are presented. | ||
