近年来，YBCO高温超导带材由于其质量和生产率的迅速提高，已被期望应用于电力系统或其他工业应用中的设备。我们的目标是研制一台体积小、输出功率效率高、用于重粒子放射治疗的高性能高温超导回旋加速器。在这样的应用中，在空间和时间上，在0.01%至0.1%的磁场范围内需要极高的精度。在施工过程中，空心饼形线圈系统产生沿着方位变化的等场强。因此，开发用于极高线圈缠绕精度的技术是非常重要的。在这项研究中，我们构建了一个实验模型的YBCO饼线圈使用高精度线圈绕线机。然后，在径向和轴向方向的缠绕误差进行了实验评估，使用一对激光位移计和表面粗糙度测试仪。建立了数值仿真模型，分析了绕组误差对磁场分布的影响。采用数值模拟的方法，研究了真实的系统中绕制误差与米级YBCO线圈磁场的关系。
In recent years, YBCO high-temperature superconducting (HTS) tapes have been expected to be applied to devices in power systems or in other industrial applications, owing to their rapidly improving quality and productivity. Our objective is to develop an HTS cyclotron with a compact body, high efficiency of output power, and high performance in heavy particle radiotherapy. In such an application, extremely high precision is required in the range 0.01% to 0.1% of magnetic field, both spatially and temporally. An isochronous field along with an azimuthally varying field is generated by an air-core pancake coil system during construction. Therefore, developing a technology for extremely high coil-winding accuracy is very important. In this study, we constructed an experimental model of a YBCO pancake coil using a high-precision coil winding machine. Then, the winding error in the radial and axial directions was experimentally evaluated using a pair of laser displacement meters and a surface roughness tester. We also developed a numerical simulation model to analyze the influence of winding error on the magnetic field distribution. The relationship between the winding error and the magnetic field of the meter-class YBCO coil assuming a real system was also evaluated by numerical simulation.
