超导体材料的进展在某种程度上被生产实用的长导体所需的相当大的努力所掩盖。然而，在大块超导材料的材料科学和在工程应用中有效使用它们所需的技术方面都取得了稳步进展。特别地，磁化的块状超导体能够充当准永磁体，具有从少量材料提供几特斯拉或更大的磁场的潜力，它们可以充当磁屏蔽并且它们可以提供自稳定悬浮。该路线图基于一个涉及广泛学术和工业参与者的研讨会（有关研讨会方法的详细信息，请参阅doi：10.17863/CAM. 586），旨在探索大块超导体应用的一些关键潜在领域。详细的技术路线图被确定为提供良好的市场机会和可行性的四个关键应用。这些是：用于体超导的便携式系统;用于医疗设备的便携式高场磁体系统;用于下一代运输和电力应用的超轻超导旋转机器;以及用于电机、设备和其他高场设备的磁屏蔽应用。
Progress in superconducting bulk materials has been somewhat overshadowed by the considerable effort required to produce practical long-length conductors. There has, however, been steady progress in both the materials science of bulk superconducting materials and the technologies required to use them effectively in engineering applications. In particular, magnetised bulk superconductors are capable of acting as quasi-permanent magnets with the potential of providing magnetic fields of several tesla or greater from a small volume of material, they can act as magnetic shields and they can provide self-stabilised levitation. This roadmap, based on a workshop which involved the participation of a wide range of academic and industrial participants (see doi: 10.17863/CAM.586 for details of the workshop methodology), aims to explore some of the key potential domains of application of bulk superconductors. Detailed technological roadmaps are presented for four key applications that were identified as providing both good market opportunity and feasibility. These are: portable systems for bulk superconductivity; portable, high-field magnet systems for medical devices; ultra-light superconducting rotating machines for next-generation transport & power applications; and magnetic shielding applications for electric machines, equipment and other high-field devices.
