ABSTRACT A new type of Nb3Sn superconductor, fiber-reinforced
superconductor (FRS), has been developed for application in high-field
pulsed superconducting magnets. This paper describes the superconducting
properties of multifilamentary FRS with a length of one meter made by a
sputtering apparatus with spools. The strain versus stress relationship
and strain versus critical current properties are compared with those of
other samples including a monofilamentary FRS. The index (n) values are
examined for the multifilamentary FRS and compared with those of
monofilamentary FRS selected from the multifilamentary FRS. A
low-Jc FRS and a high-Jc FRS prepared by the same
process are examined in terms of the critical current distribution
