Two programs are being progressed: one is a current feedthrough for superfluid helium (He II) cooled superconducting coils; the other is current leads for experimental fusion system. The paper describes the present status of the two programs, including joint experiments of a 20 kA Bi-2223 current lead developed by FZK and development of a prototype YBCO bulk current feedthrough for He II cooled superconducting coils. In addition, the test results of Bi-2212 tubes fabricated by diffusion process, applicable to HTS current leads, are described Bi_2Sr_2 CaCu_2O_8}, title = {Development of high temperature superconducting current feeders for a large-scale superconducting experimental fusion system}, volume = {Vol.11}, year = {2001} }
