Measurement of the copper to superconductor ratio (Cu/SC) in
composite superconducting wires is necessary for process control, quality
assurance, and characterization of the final wire properties.
A comparison has been made of three techniques for measuring the
Cu/SC ratio on a set of commercial wires produced for the Superconducting
SuperCollider (SSC) Laboratory.
The simplest and most straightforward technique, chemical etching, was
found to display the best reproducibility, while the electrical resistivity technique
shows the most variation and sensitivity to measurement errors, as well as
being the most difficult to perform.
The image analysis technique is fast and fairly reproducible, and is
capable of providing much more information on the wire parameters than either
of the other techniques. / Graduation date: 1993
