✦ Synopsis

Based on the theory of curved beams and the BiotÐSavart law\ a new theoretical model for magnetoelastic bending and buckling of superconducting toroidal _eld coils is developed and corroborated numerically[ In contrast to the existing models\ this model incorporates in!plane deformation of the coil[ A semi!analytical approach is used to obtain the solution to the coupled problem[ In order to validate the model and associated solution method\ the experiment of Miya et al[ "0871# is modeled[ The theoretical predictions of the critical current of coils with none or one pin support are shown to be in excellent agreement with the published experimental data[ It is also shown that the in!plane deformation has a signi_cant in~uence on the critical current[ Þ 0888 Elsevier Science Ltd[ All rights reserved

During the NET Conceptual Design Phase, the design of the superconducting coils for the toroidal system and the central solenoid changed considerably in terms of conductor layout, jacket thickness, mechanical structure, number of coils, etc. Only one concept survived the continuous changes: all the
