The Large Coil Task, an international technology program under the auspices of the IEA, has been conducted to develop large superconducting toroidal coils for tokamaks by the participation of the U.S., Switzerland, Euratom, and Japan. Among the six coils being developed under this program, domestic tests of the pool-cooled Japanese coil in June 1982 and of the forced-cooled Euratom coil in April 1984 were successfully carried out prior to shipment and installation at the LCTF in ORNL. These two LCT coils are the first ones which show experimentally the characteristics of pool-cooled and forced-cooled large coils for TOKAMAK machines. Major results obtained by the two domestic tests are described from the view of comparison of both cooling systems.
