摘要：
The National High Magnetic Field Laboratory (NHMFL) has finalized the design of two Series-Connected Hybrid Magnet Systems (SCH). Such systems have been developed at the NHMFL over last few years. Each of these magnet systems consists of a resistive insert (a group of concentric nested Florida-Bitter magnets) and a superconducting outsert wound with a graded cable-in-conduit-conductor (CICC) with Nb3Sn/Cu strands forced-flow-cooled with supercritical helium at about 4.7 K and 3.4 bar (at the inlet) delivered by a helium refrigerator. The thermohydraulic behavior of the outsert is analyzed for cyclic operational scenarios; regular thermohydraulic regimes are observed. The effects of friction factor and boundary conditions on the thermohydraulic processes are discussed.
