Self-field measurements of a REBCO Rutherford-type cable
Self-field measurements of a Rutherford-type cable immersed in liquid nitrogen have been performed. A 1-meter straight Rutherford-type cable composed of 60 REBCO tapes (12 sub-cables) was tested. The measurement results indicated that the self-field was unaffected by the cable energization ramp-rate. Based on the measurement results, a current center position within the cable cross-section was investigated during cable energization. The current center position remained unchanged during the charging. Consequently, the current distribution of the Rutherford-type cable was stable.
In addition, the 1-meter straight Rutherford-type cable was compared to other cable samples composed of stacked REBCO tapes. Under the same sample shape and cooling condition, the Rutherford-type cable and the stacked assembled in rigid structure (STARS) cable have similar characteristics with respect to the current center position during cable excitation.
