Abstract

A new method has been developed to study Ramp Rate Limitation (RRL) phenomena.1 Samples of ITBR-type cable-in-conduit (CICC) subcable were instrumented with local field sensors such as Hall probes and pick-up coils and then subjected to rapidly changing external magnetic field. We found that during fast field sweeps some discontinuous changes, or jumps occur in the local field. We believe that these jumps indicate a fast current redistribution processes inside CICC. Detailed information about local magnetic field jumps during changing field is presented. Possible origin of the jumps and their connection with RRL are discussed.
