随着1998年6月至7月第一个全尺寸原型机的测试，基于1993-95年LHC设计的长超导偶极子的研发工作已经结束。第二代长磁铁具有 56 毫米线圈孔径，缠绕有 15 毫米宽电缆，排列为 5 线圈块布局。该系列包括四个 10 m 长的模型偶极子，其线圈已在工业中缠绕和套环，并在 CERN 进行冷质量组装和低温冷冻，以及一个 15 m 长的偶极子原型，完全在 CERN-INFN 合作框架下为大型强子对撞机制造。在简要描述设计和制造的特定特征后，报告测试结果并与预期进行比较。一块磁体达到了 9.8 T 长模型偶极子场的记录，但磁体之间的结果并不能很好地重现。结论中指出了基于六块线圈设计的下一代长磁铁中将出现的修改指南。
With the test of the first full scale prototype in June-July 1998, the R&D on the long superconducting dipoles based on the LHC design of 1993-95 has come to an end. This second generation of long magnets has a 56 mm coil aperture, is wound with 15 mm wide cable arranged in a 5 coil block layout. The series includes four 10 m long model dipoles, whose coils have been wound and collared in industry and the cold mass assembled and cryostated at CERN, as well as one 15 m long dipole prototype, manufactured totally in industry in the framework of a CERN-INFN collaboration for the LHC. After a brief description of particular features of the design and of the manufacturing, test results are reported and compared with the expectations. One magnet reached the record field for long model dipoles of 9.8 T but results have not been well reproducible from magnet to magnet. Guidelines for modifications that will appear in the next generation of long magnets, based on a six block coil design, are indicated in the conclusions.
