  The High-Luminosity LHC Accelerator Upgrade Project (AUP) in the U.S. will
construct quadrupole magnets to be delivered to CERN. An initial 3 tons, over
600 km total length of conductor was procured under the LHC Accelerator R&D
Program (LARP) for this project. Programs for quality control(QC) at the
supplier and quality verification (QV) at the laboratories were solidified into
components of the overall quality plan for strand procurement under AUP.
Measurements of the critical current (Ic) and residual resistance ratio (RRR),
and related probes and techniques, are central to the quality plan. Described
below is the verification testing that has taken place at the National High
Magnetic Field Laboratory (NHMFL). Testing challenges are presented by the high
sensitivity of these wires. In addition, new RRR test software was developed to
accommodate challenges presented by meeting international standards with
existing configurations of test strands.
