Abstract:
=========
We propose, here, a non destructive method for measuring the electrical
conductivity of niobium superconducting cavities.  This RRR measurement is made
by a movable arm’s sensors which cover all the cavity.  Each sensor is a set of
two coupled inductances powered by an electromagnetic sinewave.  We access to
the fluctuations of the RRR by measuring the mutual inductance variations.  The
process of datas is made by the LABVIEW SYSTEM, and we obtain RRR map of SRF
cavities.
