Abstract

This paper describes the thermal and mechanical test results of the Cluster Test Coil (CTC) tested in the Cluster Test Facility (CTF).
CTF is the large scale test facility which was constructed for the development of high field superconducting toroidal magnet for fusion machine.
Two Cluster Test Coils (CTC-1 and CTC-2), which have average diameter of 1.5m, and maximum field of 7T, were cooled down and warmed up automatically by a computer system. Two CTC were charged up to the nominal superconducting current of 2, 145A without training.
Mechanical characteristics of CTC in charging state were studied by strain gauge and Acoustic Emission (AE) measurement and the results were compared with the calculation.
