2000年6月26日，NHMFL混合磁体成功地在设计的气膛中进行了45.1 T的试验。该磁体由管内电缆超导插头和佛罗里达BIT电阻插入件组成，前者内径为616 mm，内径为14.3T，内径为32 mm，内径内径为30.8T。1999年5月，该插件在没有外露的情况下进行了测试。该组合系统于1999年12月进行了测试，在气孔中达到了44T的峰值场强。物理实验于1999年12月在45T条件下，使用镝极片磁通浓缩器进行。在2000年第一季度和第二季度期间，对低温系统和阻性插件进行了改进。给出了从1999年12月到2000年6月的阻性插件的测试结果，并讨论了将插件升级到总容量为50吨的可能性。从2000年7月3日开始，科学实验将在净孔中进行，最高可达45吨。一套备用的电阻线圈正在建设中。(C)2001 Elsevier Science B.V.保留所有权利。
The NHMFL hybrid magnet was successfully tested to 45.1 T in an air bore as designed on June 26, 2000. The magnet consists of a cable-in-conduit superconducting outsert producing 14.3 T in a 616 mm bore and a Florida-Bitter resistive insert providing 30.8 T in a 32 mm bore. The insert was tested without the outsert in May 1999. The combined system was tested in December 1999 reaching a peak field of 44 T in an air bore. Physics experiments were run in December 1999 at 45 T using dysprosium pole piece flux concentrators. During the first and second quarters of 2000 modifications were made to the cryogenic system and the resistive insert. Test results of the resistive insert from December 1999 to June 2000 are presented along with a discussion of the possibilities of upgrading the insert to reach a total held of 50 T. Scientific experiments are scheduled up to 45 T in a clear bore starting July 3, 2000. A spare set of resistive coils is under construction. (C) 2001 Elsevier Science B.V. All rights reserved.
