摘要
本文报道实用11T超导磁体系统的研制和试验。该Nb_3Sn—NbTi混合磁体的有效孔径为41毫米;中心10毫米直径球内磁场均匀度优于1×10^(-3);在4.2K下,用单电源励磁,磁体失超中心磁场为11.8T;磁体系统配有4.2—300K可换样品稳态气泡式恒温器、大电流多样品测量杆,室温孔管、盘管形λ点致冷器和连续式氦液面汁。用25升液氦即可进行10小时以上物理实验。
This paper reports the design, fabrication and test results of a 11 te-sla economical superconducting magnet system. Using single magnet power supply, the Nb3Sn-NbTi hybrid magnet with a working bore of 41 mm quenched at 11.8 tesla central field (4.2K).The homogeneity of the magnet is better than 1 in 104 over 10 mm diameter spherical volume. The magnet system includes 4.2-300K top loading steady state vapour bubble cryostat and the sample rod, high current multi-sample test probe, room temperature sample space cryostat, Lambda point refrigerator, and liguid helium level displayer, etc.For more than ten hours scientific experimente it consumes 25 litre liquid helium only.
