  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.
