在SULTAN III设施中测试了一个40 kA Nb/sub 3/Sn导体，设计用于在4.5 K的强制氦流下工作，（I/sub max/=50 kA, B/sub max/（背景）=11 T）。介绍了试验样品和试验装置的运行情况。使用两种测量方法来研究导体在临界值附近的行为：将样品电流或温度增加到淬灭，背景场和温度或电流相互保持稳定状态。导体临界电流的测量标准与基本线相同（0.1 /spl mu/V/cm）。对所得结果进行了讨论，并与基本链的性能进行了比较。此外，还给出了有关CIC导体性能的一些结果。>
A 40 kA Nb/sub 3/Sn conductor, designed to operate with forced helium flow at 4.5 K was tested in the SULTAN III facility, (I/sub max/=50 kA, B/sub max/(background)=11 T). The test sample and the operating conditions of the test facility are described. Two measurement procedures were used to investigate the conductor behaviour near the critical value: the sample current or temperature are increased up to the quench with background field and temperature or current reciprocally kept at steady state. The critical current of the conductor could be measured with the same criterion as for the basic strand (0.1 /spl mu/V/cm). The obtained results are discussed and compared with the basic strand performances. In addition some results on the behaviour of the CIC conductor are presented. >
