RRR Mapping of SRF Cavities by a Magnetometric Method |
Safa H., Boudigou Y., Jacques E., Klein J., Jaidaine S., Bolore M. |
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. |
