摘要：

We have been developing a new type of Nb3Sn superconductor, a Fiber-Reinforced-Superconductor (FRS), to make an attempt at the application of high-field pulsed superconducting magnets. FRSs have high elastic modulus fibers such as tungsten so that the strain on superconducting layer caused by hoop stress can be reduced. Such high elastic modulus materials however, tend to have lower thermal expansion coefficient compared with Nb3Sn. The resultant tensile prestrain on Nb3Sn at liquid helium temperature brings about the degradation of superconducting characteristics. In this paper, it is shown that the strain characteristics of FRS can be largely improved by adopting a tungsten alloy , keeping high elastic modulus of pure tungsten.
