为达姆施塔特GSI的新快循环（f=1 Hz）同步加速器设计、制造和测试了两个新的原型偶极磁体。磁体基于由液氮冷却的窗框铁轭和由在T=4.5 K下用强制两相氦流冷却的空心NbTi复合超导电缆制成的超导绕组。磁体的冷质量通过0.75 mm至2.5 mm的小真空间隙与轭分离。与标准Nuclotron偶极子相比，交流功率损耗降低了2.3倍。文中介绍了两个振子样机的设计特点和测试结果。
Two new prototype dipole magnets for the proposed new fast cycling (f=1 Hz) synchrotron at GSI in Darmstadt have been designed, fabricated and tested. The magnets are based on a window frame iron yoke cooled by liquid nitrogen and a superconducting winding made from a hollow NbTi composite superconductor cable cooled with forced two-phase helium flow at T=4.5 K. The cold mass of the magnet is separated from the yoke by a small vacuum gap of 0.75 mm to 2.5 mm. A decrease of ac power losses by a factor of 2.3 in comparison with a standard Nuclotron dipole is obtained. The design features of two prototype dipoles as well as the test results are presented.
