Development of 1 kA-class PCL for Superconducting Applications

Peltier Current Lead (PCL) is a key device which was developed to decrease heat penetration into DC superconducting system. We had been developed 100 A-class PCL. This PCL was employed in the demonstration test of DC superconducting transmission system in Chubu University (CASER-2) and confirmed operating stably. We have developed prototype of 1 kA-class PCL. In this paper, we report the performance of the prototype of 1 kA-class PCL.
