高温超导体（HTS）的新改进使其成为构建下一代高场磁体的有希望的候选者。随着导体最近变得长，新的项目，如NOUGAT（新的磁铁发电，以低成本产生特斯拉）开始。该项目的目的是设计和建造一个在20 T电阻性磁体内产生10 T的HTS磁体原型。在这种配置中，严重的机械应力施加在插入件上，并且其末端经受场的高横向分量。由于导体具有各向异性特性，因此必须在与最终原型相似的条件下仔细研究。首先，本文介绍了NOUGAT项目及其背景。然后，它显示了短高温超导带材的实验结果，研究在高磁场高达23 T的变化方向。这些结果允许验证原型的电流裕度。最后，给出了第一个绕制样机，并给出了16 T下高达200 A的实验结果.
New improvements in high temperature superconductors (HTS) make them a promising candidate for building the next generation of high field magnets. As the conductors became recently available in long length, new projects such as NOUGAT (new magnet generation to generate Tesla at low cost) were started. This project aims at designing and building an HTS magnet prototype generating 10 T inside a 20 T resistive magnet. In this configuration, severe mechanical stress is applied on the insert and its extremities are subject to a high transverse component of the field. Because the conductor has anisotropic properties, it has to be studied carefully under similar conditions as the final prototype. First, this paper presents both the NOUGAT project and its context. Then, it shows the experimental results on short HTS tapes studied under high magnetic field up to 23 T with varying orientation. These results allow validating the current margin of the prototype. Finally, a first wound prototype is presented with experimental results up to 200 A under 16 T.
