制作了一个双层斜余弦θ(CCT)超导偶极磁体并进行了测试。磁体独特的心轴设计使用机加工通道和翼梁来引导绕组,拦截洛伦兹力,并避免切向应力积累。CCT磁体设计提供了“近乎完美”的电流密度分布,并且需要最小的线圈预应力。CCT磁体设计具有这些固有特征,使其成为高场加速器磁体的理想选择。使用NbTi电缆和50.8 mm净孔构建双层偶极子(CCT 1),并进行测试,产生2.4 T偶极子场。我们报告的缠绕经验,测量现场质量和淬火历史。
A two-layer Canted-Cosine-Theta (CCT) superconducting dipole magnet was built and tested. The magnet's unique mandrel design uses machined channels and spars to guide the windings, intercept Lorentz forces, and circumvent tangential stress accumulation. The CCT magnet design provides a “near-perfect” current density distribution and requires minimal coil prestress. The CCT magnet design, with these inherent features, makes it a desirable option for a high field accelerator magnet. A two layer dipole (CCT1) using NbTi cable and a 50.8-mm clear bore was built and tested generating a 2.4 T dipole field. We report on the winding experience, measured field quality and quench history.
