A scalable concept to prepare high current density windings with high-temperature superconducting material is introduced. The concept covers miniaturized high-current windings and large coils for applications in energy technology as well. The principle is based on a circular disk-up-down-assembly (‘DUDA’) and extended to rectangular coils. First measurements on the assemblies (≈40 turns) in liquid nitrogen are presented as a proof-of-concept. Centre fields of ≈40 mT and ≈340 mT are measured during steady operation and pulsed operation respectively. Operating the assemblies at lower temperatures will strongly increase the current and field performance. Lowering the contact resistance might lead to further improvements. Due to the homogenous structure in the radial direction, shear stresses are minimized and large winding heights can be realized in principle. The DUDA concept of coil windings can be used to build even more sophisticated magnetic arrangements, e.g. Halbach-arrays, or complex windings for new stator configurations of rotating machines. The optional miniaturization offers compact and powerful magnets, e.g. for accelerators too.

介绍了用高温超导材料制备高电流密度绕组的可扩展概念。该概念还涵盖了用于能源技术应用的小型化大电流绕组和大型线圈。该原理基于圆形磁盘上下组件（'DUDA'）并扩展到矩形线圈。在液氮中对组件的首次测量（≈40 圈）作为概念验证提供。≈40 mT 和 ≈340 mT 的中心场分别在稳定操作和脉冲操作期间测量。在较低温度下操作组件将大大提高电流和现场性能。降低接触电阻可能会导致进一步的改进。由于径向的同质结构，剪切应力被最小化，原则上可以实现大的绕组高度。线圈绕组的 DUDA 概念可用于构建更复杂的磁性排列，例如 Halbach 阵列，或用于旋转机器的新定子配置的复杂绕组。可选的小型化提供了紧凑而强大的磁铁，例如也用于加速器。
