Investigations into transient mechanical disturbances in internally cooled superconductor cables
Until now there has been no way of estimating the scale of transient mechanical disturbances in internally cooled CIC (cable in conduit) conductors in advance of a coil test. To remedy this, a method based on a compression test for cable samples was developed in the course of this project. For short sections of cable at room and LN(2) temperature, stress-tension hysteresis curves were traced under transverse compression. The number or the rate and intensity of individual friction or deformation events were determined using acoustic emission analysis. Relationships established between these results give an indication of the mechanical energy released in a single event.
