Abstract

The requirement for the design and construction of large superconducting magnet systems for fusion research has raised a number of new questions regarding the properties of composite superconducting conductors. One of these, the effect of mechanical stress on the current-carrying capacity of Nb3Sn, is of major importance in determining the feasibility of constructing large magnets with this material. A typical experiment for determining such data involves the measurement of critical current vs. magnetic field while the conductor is being mechanically strained to various degrees. Techniques are well developed for the current and field measurements, but much less so for the accurate measurement of strain at liquid helium temperature in a high magnetic field. For this reason, a study of commercial, metal-foil strain gauges for use under these conditions was undertaken. The information developed can also be applied to the use of strain gauges as diagnostic tools in superconducting magnets.
