我们描述了一种超导偶极子新技术，该技术在粒子加速器中使用具有显着的优势。偶极子场是通过使用以相反角度倾斜的同心螺旋缠绕线圈对获得的；这有效地消除了磁场的螺线管分量并增加了每层的偶极子含量。这种线圈配置在 85% 的线圈孔径中产生主场的系统误差 <10/sup -8/ 的偶极场。我们通过一个设计示例展示了传统余弦θ型线圈的许多固有问题被消除，并且磁体的开发和制造成本大大降低。
We describe a new technology for superconducting dipoles that has significant advantages for use in particle accelerators. The dipole field is obtained by using concentric pairs of helically-wound coils that are tilted at opposite angles; this effectively cancels the solenoid component of the field and adds the dipole content of each layer. This coil configuration produces a dipole field with systematic errors <10/sup -8/ of the main field in 85% of the coil aperture. We show, using a design example, how many of the inherent problems with the traditional cosine theta type of coil are eliminated and the cost of development and manufacturing the magnets is substantially reduced.
