高场超导体应具有高的机械强度、高的杨氏模量和高的临界电流密度。这些性能的优化在磁体及其导体的设计中非常重要。在高场屏蔽的情况下，限制线圈电流的主要因素是导体的机械性能。从导体的输运性质和力学性质之间的竞争出发，提出了一种新的导体优化方法。机械和运输性能之间的平衡计算取决于线圈的直径和施加的磁场，并应用到Bi 2223磁带的例子。
Superconductors for high field magnets should have high mechanical strength, high Young modulus as well as high critical current density. The optimization of these properties is very important in the design of a magnet and its conductors. In case of high field solenoids, the main factor limiting the coil current is the mechanical properties of the conductors. A new optimization procedure for conductors is introduced, starting from the competition between the transport properties and the mechanical properties. The balance between mechanical and transport properties are calculated depending on the coil diameter and on the applied magnetic field, and examples of applications to Bi2223 tapes are presented.
