Abstract

For the purpose of preventing the superconductor from quenching, the magnetic coil must be precompressed and be kept in high reigidity.
On the other hand, the pressure must be controlled abequately to be free from the insulation breake on the conductor caused by over precompression stress.
We investigated compressive characteristics of the laminated superconductor coil and obtained the optimum value of precomp-ression and the method of assembling the coil. Further we confirmed the steress behavior in the coil during magnet operating conditions.
