Description

Eddy-current technique based on high temperature SQUID gradiometer is a promising tool for nondestructive evaluation of material defects which result from the machining process or ageing of electrically conductive structures. We present here the outline of a new project supported by the italian Istituto Nazionale per la Fisica della Materia (INFM), concerning the realization of such a prototype NDE instrumentation. We discuss both the NDE measurement set-up (in particular, the design of the cryostat and thermal shielding, and the x-y sample translation system) and the design of a YBCO SQUID gradiometer based on bi-crystal technology.
