【 摘 要 】

Two solenoid Siberian snakes are required to obtain ion polarization in the "spin transparency" mode of the NICA collider. The field integrals of the solenoid snakes for protons and deuterons at maximum momentum of 13.5 GeV/c are equal to 2×50 T•m and 2×160 T•m respectively. The snakes introduce strong betatron oscillation coupling. The calculations of orbital parameters of proton and deuteron beams in NICA collider with solenoid snakes are presented.
