Abstract

The Japan Atomic Energy Research Institute (JAERI) is conducting Demonstration Poloidal Coil (DPC) program for investigation of superconducting pulsed-coil technology for fusion. The DPC cryogenic system is designed to cool three forced-cooled superconducting coils being fabricated in this program and the system is composed of newly developed cryogenic circulation pump, cold compressor, and vapor-cooled current leads. The installation of these componets was completed in December of 1987 and the performance test of the whole system was carried out in March, 1988. In this test, we have demonstrated that the cryogenic system meets the specifications for cooling the coil system.
