In this paper we present details of a 600 MHz HTS insert (H600) double pancake (DP) windings. It will first be operated in the bore of a 500 MHz LTS magnet, achieving a frequency of 1.1 GHz. Upon completion of H600, we will embark on the final phase (Phase 3B) of a 3-Phase program began in 2000: completion of a high resolution 1.3 GHz LTS/HTS magnet. In Phase 3B, the H600 will be coupled to a 700 MHz LTS magnet to achieve the ultimate frequency of 1.3 GHz. The HTS insert is composed of two concentric stacks of double pancakes, one wound with high strength BSCCO-2223 tape, the other with YBCO coated conductor. Details include conductor and coil parameters, winding procedure, DPs mechanical support and integration to the background 500 MHz LTS magnet. Test results of individual DPs in LN2 are also presented.

1.3 GHz LTS/HTS NMR 磁体 - 进度报告


在本文中，我们介绍了 600 MHz HTS 插入 (H600) 双扁平 (DP) 绕组的详细信息。它将首先在 500 MHz LTS 磁体的孔中运行，实现 1.1 GHz 的频率。 H600 完成后，我们将开始 2000 年开始的三相计划的最后阶段（第 3B 阶段）：完成高分辨率 1.3 GHz LTS/HTS 磁体。在第 3B 阶段，H600 将耦合到 700 MHz LTS 磁体，以实现 1.3 GHz 的最终频率。 HTS 插入件由两层同心双层薄饼组成，一层缠绕高强度 BSCCO-2223 胶带，另一层缠绕 YBCO 涂层导体。详细信息包括导体和线圈参数、绕线程序、DP 机械支撑以及与背景 500 MHz LTS 磁体的集成。还提供了 LN2 中各个 DP 的测试结果。
