Abstract
A pair of hybrid current leads (brass+stacked & soldered ReBCO tapes) rated for 12kA in steady state and for up to 18kA at pulsed over current conditions was designed, developed and tested at NRC “Kurchatov Institute” (NRC “KI”). During the experiment at LN2 temperature, the current leads (CLs) were successfully charged with 18kA at 100A/s ramp rate. To date, as far as we know, this is the highest current capacity achieved for 2G HTS current leads. The feasibility of “stack-and-soldering technique” for 10kA+ class coated conductor CLs for accelerators and fusion was demonstrated. This paper gives an overview of the leads design and presents the preliminary test results. Detailed studies of magnetic properties and current sharing process for the stacked and staggered HTS joints are also reported.
