Abstract

The compressive rigidity tests of the conduit pack were carried out in liquid helium for evaluating the coil rigidity, and the rigidity of the conduit was investigated by FEM analysis of the plane strain problem. Also, the conventional method for the estimation of the coil rigidity was proposed on the basis of the curved-beam theory, and the apparent rigidity of the conduit pack was calculated.

By comparing these results, it is recognized the outer radius of the conduit has a strong effect on the coil rigidity and the proposed conventional method gives good results with the experimental ones.
