PEP-II B工厂原型永磁体偶极-四极混合体的结果
Results from a Prototype Permanent Magnet Dipole-Quadrupole Hybrid for the PEP-II B-Factory
摘要：
我们描述了一个原型混合永磁体偶极子和四极的建设。磁体由两个长5 cm的SmCo磁性材料同心环组成。外环由组装成Halbach偶极子的16个均匀磁化块制成，内环具有以类似方式定向的32个块，以便产生四倍场。由此产生的叠加场是一个偏移的四重场，这使我们能够将场集中在PEPII B工厂相互作用区域的高能束上。偶极块被胶合到外部支撑环的内表面，并且四极块被保持在夹具中，该夹具允许在用环氧树脂灌封整个组件之前对块进行径向调整。一个广泛的计算机模型的磁铁已经取得了这个模型，我们开发了一个调谐算法，使我们能够大大减少n=3-17谐波的磁铁。
英文摘要：
We describe the construction of a prototype hybrid permanent magnet dipole and quadruple. The magnet consists of two concentric rings of SmCo magnetic material 5 cm in length. The outer ring is made of 16 uniformly magnetized blocks assembled as a Halbach dipole and the inner ring has 32 blocks oriented in a similar fashion so as to generate a quadruple field. The resultant superimposed field is an offset quadruple field which allows us to center the field on the high-energy beam in the interaction region of the PEPII B factory. The dipole blocks are glued to the inside surface of an outer support collar and the quadruple blocks are held in a fixture that allows radial adjustment of the blocks prior to potting the entire assembly with epoxy. An extensive computer model of the magnet has been made and from this model we developed a tuning algorithm that allowed us to greatly reduce the n=3-17 harmonics of the magnet.
