PERIODICITY OF CROSSOVER CURRENTS IN A RUTHERFORD-TYPE CABLE SUBJECTED TO A TIME-DEPENDENT MAGNETIC-FIELD

The behavior of Rutherford-type cables under a time-dependent magnetic field is studied. Existing models are extended describing the current s flowing through the resistive contacts at the crossovers between the cable strands by considering crossover current distributions that are not uniform along the cable axis. The generalized system of equations is applied to a few cases of practical interest and shows that, if no t uniform, the crossover current distribution is periodic, with a peri od equal to the cable pitch length.
