Sandia has successfully integrated the capability to apply uniform, high magnetic fields (10-30 T) to high energy density experiments on the Z facility. This system uses an 8-mF, 15-kV capacitor bank to drive large-bore (5 cm diameter), high-inductance (1-3 mH) multi-turn, multi-layer electromagnets that slowly magnetize the conductive targets used on Z over several milliseconds (time to peak field of 2-7 ms). This system was commissioned in February 2013 and has been used successfully to magnetize more than 30 experiments up to 10 T that have produced exciting and surprising physics results. These experiments used split-magnet topologies to maintain diagnostic lines of sight to the target. We describe the design, integration, and operation of the pulsed coil system into the challenging and harsh environment of the Z Machine. We also describe our plans and designs for achieving fields up to 20 T with a reduced-gap split-magnet configuration, and up to 30 T with a solid magnet configuration in pursuit of the Magnetized Liner Inertial Fusion concept.
桑迪亚国家实验室已成功将施加均匀强磁场（10 - 30特斯拉）的能力集成到Z装置上的高能量密度实验中。该系统使用一个8毫法、15千伏的电容器组来驱动大口径（直径5厘米）、高电感（1 - 3毫亨）的多匝、多层电磁铁，这些电磁铁在几毫秒内（达到峰值磁场的时间为2 - 7毫秒）缓慢磁化Z装置上使用的导电靶材。该系统于2013年2月投入使用，并已成功用于磁化超过30次高达10特斯拉的实验，这些实验产生了令人兴奋和惊讶的物理结果。这些实验采用分裂磁体拓扑结构来保持对靶材的诊断视线。我们描述了脉冲线圈系统在Z机器具有挑战性和恶劣环境中的设计、集成与运行。我们还描述了为实现磁化内衬惯性聚变概念，采用减小间隙分裂磁体配置达到20特斯拉磁场以及采用实心磁体配置达到30特斯拉磁场的计划和设计。
