【 摘 要 】

NICA is an international accelerator complex under construction at the Joint Institute for Nuclear Research in Dubna. At GSI Darmstadt the planned heavy ion synchrotron SIS100 has to deliver high intensity ion beams for the FAIR project. The NICA booster and collider as well as the FAIR accelerator use superconducting magnets of the Nuclotron type. The magnet design and cryogenic test results presented in this work focus on quench history, static heat leak and dynamic heat releases under pulsed operation mode, cooling down and warming up histories, pressure drop in cooling channels with two-phase helium flow.Published under licence by IOP Publishing Ltd.
