I. Introduction
Appropriate knowledge of the quench behavior is mandatory for the correct design of power superconducting devices. The quench behavior can be quantitatively assessed by means of two main parameters, the minimum quench energy and the quench propagation velocity, which are strongly by the internal architecture (type of matrix materials and corresponding filling factor) of the composite tape or wire [1]–[11]. High values for both these parameters are desirable in order to avoid unwanted quenches due to possible disturbances and to allow the prompt detection of abnormal conditions by means of voltage monitoring.
